Features to know about

Keep the Front End Level and Confident: 5,600-lb Suspension Support

When heavy gear or attachments weigh down the front end, steering and braking can suffer. The Timbren Front Suspension Enhancement System adds up to 5,600 lbs of extra support to keep the vehicle level and steady. The hollow rubber springs work with your factory suspension to resist sag, keeping your headlights properly aimed and your handling balanced under load.

Handle Rough Roads with Less Shock: Progressive Hollow Rubber Springs

Every bump and dip doesn’t have to jar the cab. These Aeon hollow rubber springs compress in stages—soft at first for comfort, then firmer as weight or impact increases. That progressive design soaks up road shock and limits bottoming out on rough terrain, giving a smoother ride while reducing wear on your factory suspension.

Stay Steady in Turns and Off-Center Loads: Independent Spring Action

When curves, swerves, or uneven loads push the vehicle off balance, each Timbren spring reacts on its own to keep things level. This independent action helps cut down on body roll and sway so the front stays planted through corners or when carrying an off-center load.

Install It Once and Go: Simple Bolt-On Design

No air lines or compressors to deal with here. The Timbren system uses vehicle-specific brackets and hardware that bolt directly to existing frame points—no drilling required. With fewer parts and no manual adjustments, it’s an easy upgrade that’s ready to work every time you are.

Video Transcript for A Closer Look at the Timbren Front Suspension Enhancement System-T44FR

Hi everyone. Aiden here with etrailer. Today we're gonna be taking a look at the Timbren Front Suspension Enhancement System. This is going to be an upgraded bump stop for the front end of your vehicle, whether it be a car like the 4Runner here or a motor home. These are gonna come in a variety of different kits and fits with different capacities and help stabilize the front end of your vehicle. Let's check it out.

So why would you be looking for something on the front end of the suspension enhancement side A lot of people are pretty familiar with airbags on the rear axle, and a lot of those suspension enhancement components are used in towing applications or maybe truck beds where you've got really heavy loads in the bed and you need extra support at the back of the vehicle. Now what the front end can do is stabilize that front end, if you do have something like a front mounted hitch, maybe a plow on a truck, or on a larger vehicle or even a smaller vehicle like this, it does help stabilize body roll a lot because these are going to be a lot beefier than the factory suspension and the factory bump stops, that is, and help limit that side to side movement as we're taking turns or driving down in like really windy conditions on the highway. So this will give a significant upgrade for those applications. As far as the construction for these goes it's going to be a hollow Aeon rubber material with a progressive spring rate. Now, what the progressive spring rate means is the more this compresses, the more pressure it has, the more it's going to work at returning the vehicle to its natural position.

So it's just going to resist more and more as it gets further compressed. As for the installation process, this particular one that I've been holding is for the 4Runner, and this one is a very basic kit. It really just has a threaded end with a bolt and a plate on the inside, but this just spreads into a factory weld done on the 4Runner. Very straightforward install. But for all the other different fits and kits, those are gonna have custom brackets and their own hardware that come with it.

So no matter what one you end up going with, if it's a fit for your vehicle, it's going to be custom fit. So the installation should be just a straightforward bolt on process. Now obviously that can vary depending on the kit and what vehicle you're putting it on, especially on the motor home side of things. But for the most part, you should be able to have a very straightforward install process with any of these kits you pick out. And to make sure you find the right kit for you, be sure to enter your vehicle information into our fit guide and use that to narrow down for the custom fit options available for your vehicle.

If you're considering some front suspension enhancement, I do think that these bump stops from Timbren are a really solid option. From the testing we did in installation on our 4Runner, they performed great. They reduced a ton of the body roll and really helped when we're going over speed bumps and just aggressive driving conditions where we need that extra support. Whether you've got a truck with a plow on it, or a motor home that you're trying to reduce body roll on, something like this can be be a huge help and it's a very straightforward solution. But that'll do it for a look at the Timbren Front Suspension Enhancement System Bump Stops. Thanks for watching.

Great ordering, shipping time, cost, and supporting information. We added a snow plow and the product did everything as advertised.

Glad we had the right fit for you Tom! Where are you located, and how much snow did you get this last season?

by:
I would say that the product is a bit pricey for what it contains. The secondary bolts came with the wrong sized nuts. Other than that, they work well to support the suspension.
by:
I have a 2006 Kodiak 2 wheel drive. Timbrin firmed up the front end to much. There in full contact with the spring. I think it to stuff and I might be removing them. The install was straight forward. Parts are as expected and quality of Timbrin is great. Just not enough cush..

I hear you, and that makes sense based on what you’re describing. If the Timbrens are in constant contact, they’re basically always engaged, which is why the front end feels so stiff instead of only firming up under load. You might actually be a really good candidate for SumoSprings part # SSF-281-47 (as long as your truck is a 2WD) They’re a similar concept but made from a softer, more progressive material, so they compress more gradually instead of feeling like a hard stop. That usually gives you support when you need it without taking away all the ride comfort like you’re experiencing now. Glad to hear the install went smoothly and the quality was there, that’s pretty typical with Timbren, it just comes down to how they behave on your specific setup. What were you mainly trying to improve up front, sag, handling, or just a smoother ride overall?

@HeatherA I wanted to improve the ride. Im guessing there is sag i was unaware of. I expected the timbren to be a bit more progressive in it softness?? I didn't think the rubber would be in direct contact withe the spring 100% of the time. I only have 56,000 on this truck. So little use but 20 years old. Next weekend we take it for a 300 mile trip and ill determine if there going to be removed or not. Is there a return policy if satisfactory performance is not met?

I love these things. They are worth the upfront expense. I have them on two ¾'s, one ½, and a minivan for road trips. This particular set is full-time active up front. I have a 2" leveling kit and I'm in em no matter what. Zero complaints though. Solid performance through all aspects. I don't run any front-end attachments.

That is great to hear! I am glad you were able to feel the difference right away. I am happy to hear that you were able to get them installed easily as well.

I installed Timbren’s front and rear on my 2020 F53 chassis motorhome. They are by far the best suspension upgrade I have done. I had previously installed Super Steer Trac Bar, Radius Rods and Safe-T-Plus, which had helped, but not as much as I had hoped. The Timbren’s finalized the package and it drives good now.

Easy install, didn't even need the brackets for my application. Really helped with sidesway in the wind and seems to help the front from dipping with extra weight. Haven't tried plowing snow yet but I think they will make a major difference

Installation was not too hard, Install Videos explain all steps in great detail. BumpStops arrived in excellent condition and was delivered in a timely manner

It good but one side with no bump had to be put spacer but the spacer was flat so the bolt did not have a lot of thread so I grind the spacer a bit so it could stay flush otherwise this might solve the problem of outter tire wear that ford transit has will find out soon

Super simple installation that took about 20 minutes. These made a HUGE improvement on steering control and bounce. Driving on the freeway is a breeze. I highly recommend this product.
by:
I watched installation videos for my FFF 53 Timbren suspension parts three times to familiarize myself with what I was going to be doing. This did help. I would say you need a little bit of experience in working on cars or trucks. This is a straightforward job with no fabricating needed. The hardware was correct. The instructions were correct. The parts fit great. I did this installation by myself. Another set of hands wouldn’t hurt but not necessary. If you’re on the fence on buying parts from Timbren, I would say go ahead and place your order.
by:
I haven/t installed them yet. I think I should have gotten a discount for the age of the "box"s the Timbrens were in. May be a credit ,, Brad

Pretty pricey but well worth it. Put these all the way around at the same time as new rear leaf springs on our c7500 topkick and it made a huge difference. It's a top heavy bucket truck and it would rock and roll just turning a corner to the point it was downright scary. Now thats greatly reduced. They also smoothed out the ride especially when loaded more than I expected.
Install was simple, perfect fit. Worst part was grinding out the rivet on the old bracket
by:
2008 Winnebago Vista Motorhome
Install was straightforward. Hardest part was getting the old bump stops out. Sway was greatly reduced on the Interstate and the rock and roll by passing semis was greatly reduced. Wish I had bought these sooner!

These bumpstops really work, they stop the front end vibration before it travels through the shocks and springs, for a smooth ride

Still working fine, the truck’s suspension has settled now the the ride is even bettet

I had a problem with getting front sumo springs relative to the rear sumo springs I purchased earlier; however, the staff at etrailer were very helpful in getting me a suspension enhancement component made by timbren which I just installed. I believe the timbren supports are going to do the job I was looking for and make me just as happy as I am with the rear sumo springs. You will notice from the photos the supports make direct contact; however, the pictures were taken on a unlevel surface and when the truck is on a level surface the direct contact is equal on either side. Also, the timbren supports provide substantially more weight capacity in the event I choose to haul my scooter on the front end of the truck. Thanks again Derek S and etrailer staff I am very pleased with the service, customer relations and professionalism experienced when ordering my parts. Thank you, Bobby (Louisiana).

The timbren springs are working out better than expected. I installled new Monroe matic RV shocks front and rear on my 2006 Chevy Silverado 1500 just prior to putting the timbrens on the front and the sumo springs on the rear and the ride is great especially with a load or hauling my travel trailer and the ride is just as smooth empty. I highly recommend the timbren and sumo springs because they fit by application and there is nothing additional to buy. Thanks etrailer.

by:
The timbrens actually did what they were suppose to do. However, once I starter driving out west I notice the timbrens were riding on the axle which cause the speedometer to jump around depending on the road. I would recommend them if you are hauling or towing a camper or RV. I was going to contact etrailer about maybe removing a spacer for one set however the other set came as one unit. The bottom line is the Timbrens does stabilize your load for safe travels. I will be contacting etrailer soon to assist in correcting the problem...Road trip from Idaho,Colorado,Wyoming,and Utah were beautiful... Thank you etrailer

I have upgraded towards trailing with my truck camper Artic Fox 990. I have not had the time to reach to etrailer for a solution with my 1998 Dodge 2500 timbrens installation. I have a new addition and will install the timbrens on a F-550 to have the same travel assurance...Pre trip test run to Key West early this winter... Anchorage 2024 Spring...Thank you etrailer

I have a very heavy "Cattle Guard" on the front of my RAM 3500 and this combined with the heavy 4WD and diesel engine the extra support from the Timbren Front Suspension Enhancement System definitely keeps the front suspension from bottoming out.

Ok it’s been a year since I’ve had the springs and I’m impressed. With how easy the install is and what you get out of it these are truly amazing. No more “squishy” feeling when towing my 22fy travel trailer. The ride is a little bumpy but I don’t care. I’m glad I found these.

Still going strong. The ride is a little bumpy but when I tow the truck doesn’t feel “squishy” whenever I make my turns. I’m still super happy about the product.

Great product. Very solid and holding up well in my motorhome. My friend has sumo springs and they have a softer ride, but they had to be replaced after a few years, due to his weight distribution. Mt Timbrens seem much stronger. A little bit firmer ride, but the shocks balance that out. I would buy them again.

by:
I like using Etrailer because i can call and talk to a person. These front ones went in pretty easy just like directions said. and they got rid of the bad bumping sound in my front end after hitting a bump. smoothed things right out.

  • How to Reduce Jolting Feeling in Steering and Rough Ride on a 1998 Fleetwood Pace Arrow Motorhome
    In order to reduce the jolting feeling in your steering you are going to want to add a steering stabilizer like the Roadmaster Reflex Steering Stabilizer part # RM-RSSA. The Reflex Steering Stabilizer contains a tempered steel spring that will work to return the steering wheel back to its normal state while turning therefore reducing the jolting feeling. The only issue that you are going to have is that they do not make a bracket kit specifically for the V10 model, just the V8 model. However,...

  • SumoSprings Versus Timbren Suspension Enhancement For a 2000 National RV Tropi-Cal 6350 Motorhome
    I prefer using SumoSprings Rebel Custom Helper Springs # SSF-172-40-2 for the front axle and SumoSprings Maxim Custom Helper Springs # SSR-181-54-1 for the rear of your 2000 National RV Tropi-Cal 6350 motorhome. You have a Ford F-53 chassis with a GVWR of 20,500lbs. I find the SumoSprings work better as they are not as stiff as the Timbren Front # TFFF53MH and Rear # TFRF53A suspension. The stiffer ride the Timbrens give you can lead to more issues inside the camper as they do not absorb...

    The correct Timbren Suspension Enhancement System for your 2000 Tiffin Allegro Bay Motorhome on a Ford F-53 Chassis is going to be part # TFFF53MH for the front and part # TFRF53A for the rear so long as you have a leaf spring suspension system in the front and not a coil spring suspension system in the front. The Timbrens will do a great job of reducing body roll and absorbing shock. In regards to the steering wheel being off-center, this is an alignment issue that you will need to take...
