Product Details

The Timbren Industries GMRP30MH SES (Suspension Enhancement System) is a heavy-duty rubber helper spring kit designed to improve your vehicle's suspension performance during towing and hauling operations. This innovative system replaces traditional air bags and metal helper springs with maintenance-free hollow rubber springs that activate progressively under load.

Key Features:

  • Hollow rubber spring design provides progressive load support that engages when weight is applied
  • No air lines, compressors, or inflation required—completely maintenance-free operation
  • Reduces rear-end sag, body roll, and improves vehicle stability when towing or hauling
  • Quick and easy installation with no drilling required—mounts between frame and axle
  • Durable Aeon rubber construction withstands extreme temperatures and harsh conditions
  • Lifetime warranty against defects in materials and workmanship

When your vehicle is unloaded, the Timbren SES system remains inactive, allowing your factory suspension to provide a smooth ride. As soon as weight is added, the hollow rubber springs compress and activate to support the load, preventing bottoming out and maintaining proper ride height. This system is ideal for trucks and SUVs that regularly tow trailers, carry heavy cargo, or support campers and fifth wheels.

I saw in a big box store something I wanted but got sticker shock with the price. Boatplicity had the extract same thing for 20% less. It was delivered to my home in a very speedy manner and was very well packed so it was in pristine condition. I will use this site again!
