Features to know about

Stay Level with Heavy Loads: 2,400-lb Suspension Support

When extra weight or equipment causes your vehicle to sag, these hollow rubber springs add up to 2,400 lbs of load support to keep things level. They sit above the front or rear axle and work with your factory suspension to stabilize steering and braking when hauling or towing. By distributing weight more evenly, the system helps prevent squat and keeps your headlights aimed where they should be.

Smooth Out Rough Roads: Hollow Rubber Springs that Absorb Shock

Bumps and uneven pavement can beat up your suspension. The Aeon hollow rubber springs take the brunt of road shock so you don’t have to feel every jolt. The progressive, convoluted design compresses smoothly at first and stiffens as loads increase, giving you a comfortable ride when empty and the support you need when loaded. This setup also helps extend the life of your factory suspension by preventing bottoming out on rough terrain.

Keep Control Through Turns: Independent Spring Action Reduces Roll and Sway

When curves, dips, or off-center loads try to push your vehicle around, each spring reacts independently to keep its side steady. That independent action cuts down on body roll and sway so your ride feels planted in turns or when crosswinds hit. Stability stays consistent whether you’re carrying tools, a plow, or a heavy trailer tongue weight.

Simple Bolt-On Upgrade: No Air Lines or Adjustments Required

Unlike air systems that need hoses and compressors, this setup bolts directly to the frame with included brackets and hardware. Once installed, it automatically provides support whenever the load demands it—no switches, gauges, or manual adjustments needed. The hollow rubber springs replace your factory bump stops for a clean fit that’s ready for real-world hauling right out of the box.

I had these installed on my 2013 Jeep Wrangler prior to installing a plow. These fill the gap that would allow the front end to dip when the plow is lifted. I also had them in my 2004 Chevy, they stabilize the front end when the heavy load is added.

I absolutely recommend putting TIMBREN on the front of any plow vehicle. I have now used these on two light duty vehicles. Currently on a 2013 Jeep, the difference is amazing. No more two inch dip when I lift the 480 pound plow. E trailer gets them out to you quicker than expected. I had mine professionally installed so I can’t attest to the directions provided, but there is always a video available now in most everything. The daily ride isn’t much affected because of tire pressure. I do run them a little fuller during plow season. This is a definite win for your plow truck.

The package arrived in only a few days, sooner than I had expected. I was impressed with Etrailer, the vendor. Opening the brown shipping box however, I was somewhat set off by seeing the Timbren SES box taped up like it went through WW3. It looked like a box that someone had opened once before and someone made an attempt to reseal it with another yard of tape. Opening the SES box confirmed my suspicions that someone had indeed attempted to install these once before and returned them as the 1 paragraph's directions were covered with greasy fingerprints . The parts looked OK so rather than wait for a second pair I just installed them. I have to say that the Timbren supplied written directions left a lot to be desired. I consider myself an above average home mechanic and I had difficulty understanding how to dissassemble the Jeeps front suspension. At the price I paid for these devices, Timbren should at least have made a better effort to create clearer directions. There was no directions on how to get the old bumpers off their perches (they are pressed in . They will only come out using some heat and a lever) , nor how to get the old cups off their perchs (there is one bolts holding each one into the perch, but bolts were so rusty I had to torch them off. I doubt the average Joe would have the knwledge, tools and determination to ge the old ones off). Don't try to do this job without using spring compressors to get the springs out. You'll never do it ! I had to google Timbren installation instructions on the internet to get peoples installation tricks off of a Jeep site. The customer who had this box before me likely gave up due to the complexity of the removal of the old units and likely sent these back to Etrailer (not Etrailer's fault).

The Timbren springs made a world of difference on my Jeep Wrangler when carrying the plow. No more down in the front or wandering on highway. Great product.

One year later, still happy with my Timbrin bump stops. Made some adjustments to my explorer to get the best ride quality , and although I didn't install them for extra load capacity, the Timbrins allow my truck to ride and handle closer to how I want it. Of course, if i do decide to tow or haul something heavy, I've already got it covered.

Thank you

  • Front Mounted Receiver Hitch That Mounts Under Bumper for 2000 Jeep Wrangler TJ
    We've got what you're looking for. The Curt Front Mount Hitch Receiver, part # C31028 mounts to the undersides of the frame members at the front of your Jeep so that the receiver opening is located under the front bumper, as you can see in the photo I've provided. If you need the front receiver to provide an attachment point for something fairly heavy like a snow plow, I'd also recommend the Timbren # TJFTJ springs which fit 4x4 models only. The Timbrens prevent the front end from sagging...

  • Front Helper Springs for a 2000 Jeep Wrangler TJ Sahara with Sno-Way Snowplow
    For your 2000 Jeep Wrangler (TJ) I recommend Timbren front helper springs # TJFTJ. These springs will provide better support than the Coil SumoSprings. Air bags could be used, the durability is not an issue, but for this application I find air bags to be unnecessary. They require maintenance, you have to add and remove the air compared to the Timbren springs that require nothing after the initial installation. Since the load of the plow is only at the front you would not need anything...

  • Recommended Front and Rear Suspension Enhancement for Lifted 2000 Jeep Wrangler TJ
    I do have a great option for you, however the Timbren Front or Rear Suspension Enhancement System # TJFTJ that you referenced will not work on your lifted 2000 Jeep Wrangler TJ. I spoke with my contact at Timbren and he said that if you have a true suspension lift where the space increased between the factory bump stops and axle, this particular kit won't work because of the coil spring suspension on the TJ model. The spacers that they have available that would otherwise be needed to fill...

  • Recommended Timbren Front Suspension Enhancement on 2013 Jeep Wrangler Unlimited with Snow Plow
    On your 2013 Jeep Wrangler Unlimited a front plow will add quite a bit of weight, so suspension enhancement is needed to keep your Jeep ride height. The Timbren Front or Rear Suspension Enhancement System # TJFTJ will not require any spacers unless your Jeep is lifted from stock. If you want to add spacers, the Timbren 1" Spacer For Raised Frame Vehicles # A25723-90AH00 or the 1/2" Spacer for Raised Frame Vehicles # TA25722-90P00 can be stacked as needed to accommodate the lift.

  • Which AirLift Suspension Enhancement System Is Recommended For 2020 Jeep Wrangler Rubicon?
    The correct rear Air Lift system for your 2020 Jeep Wrangler Unlimited is Air Lift 1000 Air Helper Springs for Coil Springs - Rear # AL60829. This will drastically reduce rear-end sag and also improve handling and reduce body roll. In order to determine which spacers you need, you will need to measure the lift blocks on your vehicle. If they are in fact 2" then you can use Air Lift Universal Air Spring Spacers for LoadLifter 5000 and 7500XL - 2" Lift # AL52420. In regard to the front suspension,...

  • Recommended Suspension Enhancement for 1999 Jeep Wrangler TJ
    The Timbren Front or Rear Suspension Enhancement System # TJFTJ, you referenced, are better for reducing sag that the bumpstops. The Timbren Active Off-Road Bumpstops # TABSJFTJ are more for off-road use than just to reduce sag when carrying a load. However, the # TJFTJ is only compatible with the 4-wheel drive model of your 1999 Jeep Wrangler TJ. If you have the 2-wheel drive the AirLift 1000 Air Helper Springs # AL60811 will help you reduce sag. With the AirLift springs you would...

    It sounds like you already have the Timbren Front or Rear Suspension Enhancement System, part # TJFTJ, installed on the front axle of your 2013 Jeep Wrangler. This installs within the springs you already have. However, the Rear Suspension Enhancement System, part # TJRJK, is only for the rear. It also replaces the bump stops alongside the springs on the rear, not within them. This is the one for your rear since you already have the others on the front.

  • Will Air Bags Fit on a 2004 Jeep Wrangler Unlimited with 2 Inch Suspension Lift
    You would have to have the vehicle return to stock height in order to use the Coil-Rite system, # F4157, because of the extra space from the lift. There are no spacers for the Coil-Rite systems to adapter to the lift on the vehicle. What you may want to look at is a Timbren system, # TJFTJ, and added a couple of spacers per side, # A25723-90AH00, which is a 1 inch spacer. For 2 inches on each side you would need 4 total. The Timbren system will work to level the vehicle, especially when...

  • Suspension Enhancement Kit for 2019 Jeep Wrangler with 2-1/2 inch Lift
    Hey Eric, we have one solution that will work with the Timbren kit part # TJFTJ with spacers to take up the extra space created by the lift kit. You would need a total of 4 1-inch spacers part # A25723-90AH00 and then two 1/2 inch spacers part # TA25722-90P00 and you'd be set. There is a spacer solution for any of the air bag kits or any other suspension enhancement kits that fit your Wrangler. This is only solution that works with the lift.

  • Recommended Suspension Enhancement and Plow Setup for 2013 Jeep Wrangler
    The Timbren Front or Rear Suspension Enhancement System # TJFTJ are all I recommend before putting a plow on the front of your 2013 Wrangler. If you don't have a plow yet, I recommend the SnowBear Personal Snowplow for 2" Hitches - Electric Winch - 84" Wide x 22" Tall # SB324-081 for the 5 angle options along with the Curt Front Mount Trailer Hitch Receiver - Custom Fit - 2" # 31432 which gives you other options when not plowing.
