Specs:
When hauling heavy loads in the cargo area or by pulling a trailer, you will often see the rear of the vehicle sag while the front end rises. In these cases, the rear axle is handling not only the weight of the cargo, but more of the vehicle's weight as well. Because less weight is on the front axle, the front tires are making less contact with the road. Overall vehicle handling - traction, steering, and braking - is negatively affected. The resistance from Timbren's Suspension Enhancement System works with the vehicle's factory suspension to keep the vehicle level and improve your driving performance.
The Timbren system has a vehicle-specific bracket that will be bolted onto each frame rail above the rear axle. Hollow rubber springs are bolted to the bottom of the bracket and hang down to where the bottom of the spring sits one inch above the axle. The inch of clearance allows the existing factory suspension to operate normally under light loads and standard terrain, ensuring the smooth, comfortable ride you are used to.
Timbren Suspension Enhancement Systems are designed to work progressively. When the hollow rubber springs are compressed, the convoluted design causes them to quickly collapse along the folds. Once the folds are compacted, the stacked barrel shape provides increased resistance, stiffening the suspension and keeping the vehicle level.
Each hollow rubber spring works independently to support the driver's or passenger's side of the vehicle. This is helpful when you swerve or make sharp turns. Each spring is activated when it is needed, so body roll is greatly reduced. The independent action also works well when hauling off-center loads.
Because the vehicle handles better with the springs, less turbulence will be passed along to the trailer helping to keep the trailer in line. Your driving comfort is further enhanced if the trailer does begin to sway (from a gust of wind or passing of a semi) because the movement from the trailer is not transferred to the vehicle. This also works to make the sway subside quicker.
Another great feature of the rubber construction is that the springs absorb most of the road shock, creating a smoother, more stable ride overall. Wear and tear on the factory suspension is also lessened as the rubber springs work to prevent bottoming out on rough roads.
Compared to the competition:
Timbren's suspension enhancement systems are much easier to install than air springs - no air hoses are needed to be run, no compressors or gauges to hook up, and no manual adjustments necessary. The rubber construction causes Timbren's springs to be more elastic than similar products constructed of micro-cellular urethane. More elasticity allows for a more comfortable ride because the rubber has more travel.

6,000-lb Capacity. These hollow rubber springs sit above the rear axle to help stabilize and level your vehicle. They also provide a more comfortable ride by absorbing road shock and improving roll stability. Easy to install and use.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
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
Tom P - 07/29/2018Great information and tracking ability. Package arrived on time as promised. Installed the kit the next morning, fit perfectly 567633
Great product. Makes truck ride a little stiffer but it is worth it when loaded or hauling a trailer. No more sag and handles better when trailering. 651679
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
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
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
Frank P - 07/20/2017Works perfectly, very easy to install does exactly what it said it would. Have 6000 pound 24 foot travel trailer truck sets perfectly level have F150 half ton 4 by 4. 600324
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
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
Mike L - 07/24/2018 russell w - 07/23/2019Not 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 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
Very happy with these products. Super easy to install. 610949
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
Blake - 07/19/2019I 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
Mike L - 01/30/2018Solid 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
Cory - 05/22/2019Product 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
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
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
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
Great Addition to my F150. I occasionally carry a heavy load, and this really helps keeping the truck level. We also tow a camper and it helps stop sagging when going over bumps and valleys. 857029
I towed a 26 ft. Travel trailer 600 miles last week with the new Timbrin’s in place. They kept my load level and helped stabilize sway. A good product overall! 851390
I tow a travel trailer. I bought these to help the rear springs recover quicker over bumps. They work great. I feel much more in tune with the trailer now and less bouncing. The item shipped and arrived quickly. 845253
Easy to install , works as it should. The only issue I had was they interfered with my Roadmaster active suspension system so I had to remove it. I wish I could’ve kept both unfortunately on the newer Fords that’s not possible. 817625
