Timbren Rear Suspension Enhancement System

Solid Product! Yeah it's a stiffer ride when loaded But that's the sacrifice made to have more control of the haul while underway. Definitely recommend to anyone wanting to stay more level with a heavy boat/trailer setup as in my case. Not that install is hard but removal of spare tire before install, may have helped with space if you don't have a lift. 511931

Night and day difference while towing. This is one of the best additions to my truck. My camper is around 7k pounds. My back end doesn't sag as much and doesn't bounce as ki when towing. Not noticeable when unloaded. I recommend this to everyone e who tows. 613728

Bought these to help with body sway while pulling a 22 ft camper. They really helped and were easy to install. 568570

Product has done exactly what I wanted it to do while towing with the F150 (Limit the sag and porpoising). The only potential negative is that you will bottom out easier over speed bumps but you can avoid that by slowing down to a normal speed. Also after 6 months you rarely feel it. Great Product and worth every penny. 488710

got the product when stated , went on simple enough but used google to really see how things went together. Timbren doesn't give very good instructions with their product wish they would put diagram so as to be able to see how brackets go, but happy so far haven't put load on the truck yet that's coming up with a trip in august with my 30ft camper and truck loaded for trip guess will come back and let you know how the product works after the trip , but etrailer delivered when they said they would thanks will keep you in mind for future purchases. 544811

Timbren Rear Suspension Enhancement System Installation - 2016 Ford F-150 - Video

Not sure if it was a returned product or horrible packaging on Timbren's part but the item was only about 75% painted when it arrived. It was pretty obvious the parts where banging together in the box which made a large portion of the paint chip off. Raw steel exposed to salt during the winter would eat these things alive. Not looking forward to spending several hours sand blasting and repainting a product that was suppose to come that way. 406297

Product works great, 100% better when I’m towing. I have absolutely no complaints about the product. The only issue I had was the package was short 2 washers that the instructions called for. I didn’t contact the company, because I have Spare washers and it was a lot easier to use what I have versus contacting them. 574500

Product arrived within a business week. Took a couple days for me to get around to installing it on my Ford 150 Lariat 4x4. Not bad to install, I had to do it laying on my back in my garage. Finally hooked up my 4th wheel to my Andersen hitch today. Truck was level, 5th wheel was level, and I was happy. Ready to rock 'n' roll. 420451

I wanted to try to get some support when pulling my 33 foot RV trailer. It does a wonderful job of support the ride and stability. But it does give a stiffer ride when empty. I wish there will be a redesign of the ride when empty. But as for the support when towing, it's great. 429047

The Timbren TFR1504E fit my 2016 Ford F150 truck perfectly. It was easy to install using just a floor jack and a jack stand. I bought this enhancement system because my wife and I enjoy camping and pull a Rockwood travel trailer. Prior to installing the system I had noticed some squatting and body roll when towing. Not sure how much this system has helped because I have not towed the trailer since installation. 412158

It is working great.

Tom P - 07/29/2018

Rear suspension pads work great. Ride is still like factory with no load unless driving over a big bump at high speed. When towing a 32 foot travel trailer the sag in back end of truck is greatly reduced with a lot more control. Easy to install. The downside is when truck is full with passengers and not towing anything the added weight makes the ride rougher. Shipped on time. 575558

Installed on 2016 F150 Platinum, without jacking it up, in 1/2 hour per side. One part has word "LEFT" printed on it, yet there is no diagram showing which is left. Seemed obvious it was driver side, but clarity of diagram would have helped. Stock bumpers had maybe 6" of gap. These have about 1.5" of gap. I was very concerned about the backend hopping when hitting small bumps (unloaded). Maybe 15 miles of driving and I simply have not noticed this replacement at all. Thats a great sign. Next month I will tow trailer, that is the important test and the reason for purchasing this upgrade. 521868

I am so glad to have foud this product, and thus the best solution I could have wished for since I realised that my 2016 F150 was sagging a bit too much when fully loaded with my travel trailer attached. Very easy to install. Now everything is straight! And the beauty of it is that the suspension works normally when there's no load in the truck. Love it. 358151

Ford F-150

We have plans to take our pop-top-slide-in camper to Alaska this coming summer. When we first bought the camper we had an F-350, no problems. But as it was getting a bit old, as we are too, it was time to trade up. We were sold on the F-150 with the Eco-boost, the sales guy said "not to worry" and a car sales guy would never fib.. right? Thing is the engine does fine, lots of torque, a haul-tow mode for the little hills in the west, and really great fuel economy. But our little 1100lb camper had a mind of it's own on the light suspension. Enter the rear suspension "helper", goes on easy, works great. Except (a little except for the folks in the back seat of the crew cab) they get a pretty hard ride. No big deal, I'm driving. 486776

I just completed installation of my Timbren Rear Suspension for my 2016 Ford F150. In 2012 I purchased this same product from etrailer for my Ford F150, which I upgraded to the 2016. I have a 5th wheel and the Timbren product allows my vehicle to be perfectly level in all situations. A great product!!! 274107

After 1 year heavy use, I still strongly recommend the Timbren shock as the perfect solution for a level towing, hauling ride.

Frank P - 07/20/2017

I like this over other suspension upgrades because it is passive when the truck is not carrying a load or trailer tongue weight. The spacers were not needed on my 2015 2WD Supercab. Very simple install. I recommend installing the upper bracket first and then the rubber spring. 566770

Great company to work with. Install took less than 30 min and didn't even have to jack the truck up to do it. Made a huge difference when towing our large travel trailer. Much smoother ride and trailer feels more controllable. One bad thing. When I opened the box the pieces had all banged around in there for a while. The paint job was very poorly done so a lot of the paint had chipped off. I'm gonna take them back off and have them powered coated (like the manufaur should have done) before the road salt gets to them this winter. 418490

Made a huge improvement in towing.

I have a 2016 Ford F150 Regular Cab with 6.5 foot box and 5.0 engine, 6400 lb payload package, 9.75" ring gear with 3.73 gears with a locker. (Hard to find!) Ease of installation is easy, with even minor mechanical skills. I took my time and it was 40 minutes to install both sides. Took some measurement of the factory bump stop distances to the axle - 6.5 inch's approximately. (Would take a lot of weight to compress it that far!! Have hauled some rocks before, almost 1 ton and it was still 3 inchs from touching the axle!) After installing I took some measurement of the gap between the plates and the rubber that will come into contact with when the suspension compress's. Left side (Driver) was 1.25 inch. (Full gas tank.) Right side (Passenger) 1.50 inch. Have not driven it yet to see how the suspension will ride before these Timbren Rubbers will come into play. Purchased these to help when I haul a 700 Yamaha Grizzley ATV (750 lbs approx.) and tow a camp trailer with a 550 lb tongue wt. approx. Separately the truck would be level, but with both it was squatting it to much. I am hoping this helps in that situation & to help stabilize the ride. Gave a 3 for easy of installtion, but yet to be determined how well it will help when towing & or hauling ATV or both, and how the ride will be empty. 471198

I spoke with my Timbren representative, who tells me that its likely the full tank of gas is causing the 14 inch space differential between the driver/passenger Aeon spring and the axle. They do have spacers available that are as small as a half inch, but all that would do in your case is make the other side 1/4 inch closer to the axle. Any load thats capable of compressing the suspension so the springs contact the axle would cause both springs to contact at the same time, so that small differential wouldnt be anything to be concerned about. Let us know if youre interested in the spacer, Timbren will send you one if youre interested.

Ordered these (6,000 lb Kit) to cure getting too nose high when towing after installing a Bilstein 5100 Level Kit on my 2016 F150 SuperCrew 4x4 (front struts set on max 2.10" setting sitting nearly perfectly level). Tow a 29' overall length travel trailer (~5,500 lbs) and for work we use a 20'x8' enclosed trailer (~9,000 lbs when loaded). Use a WD hitch, but still get the nose up when pulling both. Install was easy. Read through the instructions and watched a video before they came in. Crawled underneath and installed in about 30 minutes after I received them. Didn't remove the spare or the heat shield like the video I watched showed. A lift would have made it easier of course, but can be done in the driveway if you like doing stuff yourself. Used the included spacer and have about a 1" gap, which falls in the advised .5" to 1.5" range from the instructions. I haven't gotten to use them with the work trailer, but I have pulled the travel trailer and they do exactly as advertised, cures the sag, and nose doesn't go up at all. May be slight nose up with the work trailer, but I wouldn't believe it will be like before. Driving while hooked up feels smoother, too, with less body roll/lean in turns. So, overall satisfied with the purchase. The only reason this is getting 4 stars is that, like others have stated, the parts that were painted left a lot to be desired. Very sloppy with some areas that were already flaking off and one part had a spot that was completely missed by paint. The piece that goes underneath the axle to secure the contact plate is not even painted, it's just raw metal. So, I'm curious about what that will look like after one salty winter here in MO. I may find some time before the winter hits and take everything off and do some painting myself, but for $215 you'd kind of think that wouldn't be something to worry about doing with a brand new part. 543563

Self Installed on my 2017 Super Cab F150 4x4. Stock unloaded ride height was 9 3/4" clearance from top of tire to bottom of rear fender arch. I pull about a 5500 lb travel trailer with WD hitch. This lowers ride height by 1.5" to 8 1/2" clearance. Installation was straight forward, only issue for me is that the lower bracket that goes around the differential/axle was unpainted raw steel. I shot some matt black enamel on it to help with rust before installing. I did not use the extra rubber disc, as there would of been only about 3/4" of axle travel unloaded and I did not want an overly harsh ride. A test drive unloaded, showed that the ride was only slightly more stiff, and not enough to make much of a difference of a stock ride without. There is about 2" of gap or free travel of axle to rubber stopper when the truck is unloaded. Loaded/towing my trailer, the ride was improved over stock -no Timbren. I have about 1 " of travel before contact is made with the rubber stoppers. This smooths out the 'bucking" or sway motion that you can sometimes get while towing on uneven surface roads at speed. I would only recommend adding the extra rubber spacer disc if you regularly carry a large payload. This is a good product for a great value, that will make your towing, or load carrying more comfortable and safe. I would've rated 5 stars except for two reasons: the unpainted brackets and the thread area on the rubber mounts that is fully loaded with paint and makes threading the rubber mount bolts more difficult than it should be. 472157

Etrailer did an excellent job. 2 day shipping for less than $8. No brainer. Staff was helpful on the phone answering questions. I ordered online and that was easy as well. Product: these went on 16 F150 4x4 supercrew with tow package and e rated upgrade tires. I use the vehicle to pull 7000 lb travel trailer. Purpose for the purchase was to help with sway and slight sag in the rear. I use a wdh with sway but that was not performing good enough. I choose these after some research. Install: easy. I didn't use a jack or lift. I just assembled with one inch spacer. I had an inch between the bottom of the timbren and the stop plate. I am no mechanic. Unloaded was pretty much what I expected. You hit a big bump, you get some jarring. 90% pleased. First tow with 16'6" boat (full windshield). The timbren was not engaged from the weight of the boat. Bumps were a little ruff. Added weight from equipment will take care of the space and ride should be better. 85% pleased with towing the boat. Travel trailer tow. Almost completely leveled truck with combination wdh and timbren. Was able to comfortably tow. Took out most of sway I had experienced. Almost 0 bounce, even at low speeds. Basically did everything I wanted it to do. 95% pleased. 4 stars because the unloaded ride is stiffer than I would like and pulling the boat maybe a tad ruff without equipment. This will be especially true in ruff roads. But at half the cost of air bags and ease of installation I do think they are worth the money. Would recommend to those that do not mind a rougher ride every now and then. 377432

Recently installed these on my 2016 F150 4x4 Supercrew. Product was shipped quickly and arrived on schedule, and boxed up nicely. Install was relatively quick - about a 1/2 hour (a ratcheting wrench was helpful). Towed the boat and gear again for an annual trip, and the sag I experienced last year was greatly diminished and the truck handled better. Ride is very comfortable while on the rubber. Unloaded, there is a bit of a jarring bump when the rubbers are contacted after the 1 1/2 inch gap, but its only noticeable if you remember how it rode before... They did their job, and I would purchase again. However, as others have pointed out, the finish on the metal parts leaves some to be desired - the paint was flaking off at several locations of the parts in the box. Since the install, rust is apparent on these locations. I will be removing, removing the rust, and refinishing to make it more durable... 526471

I have been towing a 7500lb camper with my 2015 Ford F-150. Prior to installing the Timbren suspension, the sag in the back was very noticeable. The F-150 also is known for having a softer suspension which translates into more suspension travel while under load, making for a very "boat in the waves" type ride. After installing the system, which took about half an hour, there is a noticeable difference. The rear end hardly drops once the camper is hooked up and the ride is much better. I would highly recommend this product to fellow F-150 owners as it makes towing a heavy trailer much easier. The installation was simple! I did not install the spacers and I did not even need to jack up the truck to install the product. I had plenty of room underneath the truck. It only leaves about an inch of gap between the timbren bag and the axle versus the wide gap of the factory product. You will notice it, while not under load, if you hit a large bump. Other than that it is pretty unnoticeable when traveling with no load on the truck. Thank you Timbren! Roger 514301

Purchased these to help with our new, much heavier camper, which is 8,600lbs and 36' with a 950lb hitch weight. Tow vehicle is a 2016 F150 super crew Lariat with max tow option. I wanted a little extra support back there with the increase in what we were towing. Installation was straight forward and very simple. No cutting or drilling. I choose to run these with without the included spacer. With the spacer installed, the ride quality over large dips in the road or large bumps is definitely very noticeable, and much harsher. Small bumps or smoother roads you don't notice them installed. Without the included spacer I don't notice them there not towing. Was a nice increase in support while towing, and made the truck feel more solid out back. With these and no spacer, the rear squats right around 1.5". I have not towed with the included spacer installed. Docked these one star due to the harshness with the spacer installed. 382475

This was used on a 4 wheel drive Ford F150 to tow a 7000 pound travel trailer. Installed with spacer. While towing it definitely improved performance and stability. When towing use a weight distributing/anti-sway hitch. Without the trailer driving on smooth roads there is no impairment in the function of the truck. On slightly rougher areas or speed bumps there is a sharp end point. 669974

One year review. I tow a 5th wheel or a car&trailer I am super happy with the stock ride when unloaded and the level ride when loaded. I chose over air bags for zero future maintenance. I chose wisely. 654516

Update after 1 year. Timbren springs still working flawlessly, great purchase and easy installation on my 2018 F-150. Recommend highly. 642972

Fairly simple to install. Did not have to Jack up my 18 f150, but would have probably made it easier. Install was pretty straight forward bolt on operation. I Haven't pulled my 28 ft camper yet. The bump stops I removed were 1/3 the size of the new ones. They should work real well. No noticeable ride difference with no load. Thanks. 641299

One year in and we don't even know it's there. The ride while towing and hauling a very heavy load in the truck bed has been perfect. We have gotten used to the stiffer ride, so we forget the units are installed until we need them. 640367

Easy to install. Less than 1/2 hour per side and I did not have to Jack the truck up or remove the spare tire to install. Only bad thing was painted surface on the mounting hardware was partially missing with bare metal showing. Installed on a 2019 F150 crew cab with a 6 1/2 foot bed. 637493

1 hour installation- all parts well made- fitment. was good. Only issue was holes in u-bolt saddle were large enough that the nuts went through the holes-3/8 washer solved the problems 635853

The Timbren ses went on easy and worked like a charm. Thanks so much. 635842

Product was as advertised. Problem was that after it arrived in San Diego it was sent to Ontario and then back 2 days later. Not a product problem but a UPS problem! 629015

TFR1504E Timbren. fast shipping. very well packaged. 2018 f-150 I tow a 8100lb camper it made a huge difference in the sag and sway, truck handles the camper with ease and it didn't change the ride of the truck when not towing. 617814

Pulling big boats puts duress on my suspension. This order is for another vehicle I own and the install and expectations are exactly what I expected from this product. Without them, the boat i'm towing settles the back end too much and is too soggy in the suspension. I'd order them again if i had to switch to another tow vehicle. 613180

2016 F150 FX4. Less than an hour install time. I had plenty of room under my truck. did not have to remove the spare or the exhaust shield on the passenger side of the truck. I am very pleased. I tow a 7000 pound travel trailer and use leveling bars. With new product I don't have to put near as much strain on the bars to keep the vehicle level. 602918
