Features to know about

Keeps Heavy Loads Level and Steady: 16,000 lb Capacity Rubber Springs

When you’re hauling serious weight, sag and sway can make towing stressful. This Timbren Trailer Suspension Enhancement System uses two hollow rubber springs rated for 16,000 lbs that mount above the axle to stabilize and level the trailer. The springs get more rigid as the load increases, giving extra support only when you need it. The result is a trailer that stays level and tracks straight, even when loaded down.

Smooths Out the Rough Stuff: Hollow Rubber Springs Absorb Road Shock

Rough pavement or uneven roads can shake a trailer hard enough to rattle everything inside. These hollow rubber springs act like shock absorbers, cushioning bumps and potholes to reduce bounce and body roll when swerving or cornering. Each spring works independently side to side, so the trailer handles off-center loads and turns with less lean and better control.

Raises Ride Height and Reduces Strain on Hitch Components

Heavy loads can cause the trailer to squat, putting extra tension on hitch hardware. The progressive resistance of the Timbren springs helps raise the trailer ride height under load, taking pressure off the hitch and helping the suspension ride easier. It also helps keep the trailer closer to level, improving overall towing stability.

Built for Long-Haul Durability: Direct-Fit Mounting with Solid Hardware

This system installs directly onto the trailer frame with included brackets and mounting hardware. Each spring measures 7-3/8" tall x 5-7/16" diameter unloaded and 2-15/16" tall x 8-7/8" diameter when fully loaded. The hardware and brackets are designed for a secure mount, with welding and drilling required for installation. Once in place, the setup works seamlessly with your existing suspension to extend its life and keep performance consistent over time.

  • Best Suspension Upgrades For 2025 Jayco Pinnacle 36' 5th Wheel
    Hello Mark, thanks for reaching out. As far as suspension enhancements for your 2025 Jayco 5th wheel, what I recommend is a cushioned equalizer and wet bolt upgrade kit. That will add shock absorption to the suspension, and the HD shackles and wet bolts are extremely durable. I also recommend adding a shock kit like the Lippert Bolt-On Shock Kit w/ Heavy Duty Gas Shocks # LC281281. Those will go a long way to really smooth things out and help the camper handle bumps in the road without...

  • How Much Air Pressure Should Be Run in a Ultra-Fab TrailAir Air Ride 5th Wheel King Pin
    According to Ultra Fab there are many factors that can effect air pressure such as the size of the air spring in diameter and height, the pin weight of the trailer, the mechanics of each individual hitch, altitude and air temperature. Ultra Fab has stated that usable air pressures can range from 20 to 120 psi. Therefore a specific air pressure is not recommended. Instead it is recommended to inflate the air bag to maintain a ride height. To determine the ride height Ultra Fab has indicated...

  • Timbren Suspension Kit to Help Stabilize 8,000 lb Trailer
    Yes the Timbren Trailer Suspension Enhancement System Heavy-Duty Trailers # TTRA5602 would help stabilize the suspension of a trailer, but since your travel trailer weighs 8,000 lbs this would be too harsh since this is for a 16,000 lb axle. Instead you'd want the part # TTRA1032 which is more appropriately rated for your trailer.

  • Will Timbren Kit for Trailer Suspension Work Like Air Ride
    The Timbren kit part # TTRA5602 that you referenced is designed to give additional support to trailer suspension but it would not perform anything like air ride suspension. If anything it might make the ride quality a bit harsher since the suspension would be stiffer. This kit would be if you were hauling heavy and near the capacity of your trailer and wanted more support.

  • 5th Wheel Trailer Pulls to the Right After Making Right Hand Turns
    It is possible that the trailer is heavier on the one side causing the suspension components to wear unevenly. I recommend inspecting the suspension and look for signs of excessive wear such as egg-shaped holes, flat springs, broken parts, and anything out of the ordinary. When replacing suspension parts you should do both sides of the trailer at the same time so that they wear more evenly. Something that will help the suspension to last longer is to install some helper springs. We have...
