Features to know about

Stay Level When Front-End Weight Adds Up: 4,000-lb Suspension Support

Heavy front-end equipment like plows or mounted gear can make your vehicle nose down, throwing off handling and headlight aim. The Timbren Front Suspension Enhancement System adds 4,000 lbs of load support through hollow rubber springs that replace the factory bump stops. They work with your existing suspension to keep the front end level, improving steering, traction, and braking under heavy weight so your setup stays balanced and safe.

Smooth Out Rough Roads: Progressive Rubber Springs Absorb Shock

Every bump and rut sends a jolt through the suspension when the weight’s up front. Timbren’s Aeon hollow rubber springs act like built-in shock absorbers, cushioning impacts and reducing harsh bounce. Their progressive design compresses easily at first for comfort on light loads, then stiffens as weight increases to maintain stability. The result is a smoother ride when loaded and less wear on your factory suspension.

Reduce Sag and Body Roll: Independent Side-to-Side Action

Uneven or off-center loads can twist your suspension and cause sway through turns. These springs work independently on each side of the axle to handle uneven pressure and reduce body roll when cornering or swerving. That independence keeps your handling predictable whether you’re carrying a centered plow or gear that sits off to one side.

Bolt-On Upgrade Without the Hassle: No Drilling Required

Installing load support shouldn’t mean tearing into your truck. The kit includes two custom-fit hollow rubber springs, vehicle-specific brackets, and all hardware for a straightforward bolt-on setup—no drilling or airline routing required. Once installed, the springs automatically engage as needed with no manual adjustments or maintenance to worry about.

2016 Dodge Ram Pickup

I purchased the TDF15004B and TDR1500DQ products for my 2016 Ram 1500. Towing is way better and overall handling is improved. These products installed just fine. The directions were clear and concise. Etrailer has a helpful video series as well. Thanks to the staff at Etrailer for the great customer service and follow-up.

Great! I appreciate the follow-up. No complaints, performance is excellent. Ive recommended both of these products and informed them E-trailer is the source.

Easy to follow directions. Quality material, but difficult to do solo. Definitely try to have an extra set of hands to assist.

Great product and has helped with increasing the lifespan of my front suspension. I'm able to plow much easier now knowing that isn't going to hit the ground when going down the road to my next house.

Install was easy
Directions should relay that the smaller piece of hardware goes into the frame but past there all is great. Just waiting for the snow to fly to really test the strength of the product with the plow on.

Great product and easy to install as per the directions that were included. I would recommend them to anyone in need of this kind of product for your truck.

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

by: Kerry 09/11/2026

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.

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?

Jess

5/8/2026

@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.

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.

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: Tory 07/26/2025

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.

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

Nissan Leaf

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: James 07/20/2026

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!

Front Suspension Enhancement For 2021 Ram 1500 Classic With Snow Plow
Hello Lawrence, thanks for reaching out. Beefing up the front suspension of your truck is definitely a good idea if you plan on adding a snowplow, and I do have a good option for you. That said, there are no front air bag kits made for the 2021 Ram 1500 Classic 4x4. What I recommend instead is the Timbren Front Suspension Enhancement System # TDF15004B. These are 4,000 lb capacity rubber jounce-style springs and they will do a great job supporting the front of the truck while you plow....

Front Axle Suspension Enhancement Kit for 2012 Dodge Ram 1500 4x4 Long Horn with Western Snowplow
A 400-lb Western snowplow on the front end of your 2012 Dodge Ram 1500 4x4 Big Horn can certainly give you reason to consider a front-axle suspension kit to reduce sag. Thank you for the photo of your truck and plow. We offer SuperSprings kit # CSS-1168F that fits both crew and quad cab versions of your Ram 1500. This kit offers the advantage of installing inside your front coil springs, which means that there is no concern with interference with your plow's mounting hardware. Please refer...

How to Reduce Front End Sag from a Snow Plow on a 2015 Ram 1500 Big Horn
As long as your 2015 Ram 1500 Big Horn is a 4x4 then the best option we have to help with front end sag due to the snow plow you have installed is the Timbren Front Suspension Enhancement System part # TDF15004B which is actually designed specifically for this purpose. They are easy to install, do not require any drilling, and come with a lifetime warranty. The best part is they won't affect the unloaded ride quality much at all.

Will The Timbren Front Suspension Fit a 2021 Ram 1500 Classic Warlock Edition For Use w/Snow Plow?

This will help to reduce the front suspension drop when using a Snow Plow # K2SUMM8826ELT with the Mounting Brackets # K284314.

I do have an option for you but we only offer an upgraded rear anti-sway bar for a 2017 Ram 1500, the Roadmaster Rear Anti-Sway Bar part # RM-1129-135 which like a front anti-sway bar will work great to reduce body roll and improve stability. The only type of suspension enhancements we offer for the front are the Timbren Front Suspension Enhancement System part # TDF15004B or similar which like a sway bar, can reduce side to side rocking but admittingly won't be quite as good as an anti-sway...

Timbren Front Suspension Enhancement System Item # TDF15004B Add Lift to truck
The Timbren part # TDF15004B that your referenced would not provide you with any additional lift when installed on your truck. This is for support when under load. If anything it would cause the ride quality to get harsher if you were deep enough in the stroke of your suspension that this product was activated.

Recommended Front Suspension Enhancement Product for 2014 Dodge Ram w/ Snow Plow
If the front end of your Ram 1500 sags significantly once a plow is installed, a front suspension enhancement product is exactly what you'll need. I'd recommend the Timbren # TDF15004B because the Aeon spring is actually bolted to the vehicle, rather than being zip tied to the coil springs like the SuperSprings # CSS-1168F. I've had no reports of the # CSS-1168F failing, but I'd prefer a more permanent, substantial attachment method.

Will the Timbren Front Suspension Enhancement System for a 2013 Ram 1500 4x4 Work With Lift
The Timbren Front Suspension Enhancement System part # TDF15004B is a fit for a 2013 Ram 1500 4x4. That said, if the vehicle has been lifted you will need to add additional spacers as you mentioned. The Timbren Spacer For Raised Frame Vehicles part # A25723-90AH00 and part # TA25722-90P00 will need to be added to compensate for the lift. That said, you'll also need longer bolts as well but you can get these at a local hardware store.

Will Timbren Suspension Enhancement Allow Front Mount Carrying of a 300 Pound Scooter
I am not sure if 300 pounds would be a problem for the stock suspension. If it is, a Timbren Front Suspension kit would certainly be able to compensate. These kits are very popular among snow plow guys. They relieve some of the stress placed on the front suspension when plowing and this extends the life of the suspension. Since the Timbren kits handle this kind of work load, they should have no problem compensating for a 300 pound scooter.
