The Timbren GMRG35 is a Suspension Enhancement System (SES) kit with a set of two Aeon hollow rubber helper springs for the rear of the Chevrolet Express and GMC Savana 2500/3500 vans plus older G30, G35 and G3500 vans. As the load increases, the hollow rubber springs push back harder, which cuts sag, sway and body roll when you tow or haul without spoiling the unloaded ride. Rated at 3,600 lb per set, it comes with helper springs, brackets and hardware; total load must still stay within the vehicle's gross weight rating.

  • 1996-2026 Chevrolet Express 3500 — rear

Features

  • Eliminate suspension sag: when towing a heavy trailer, Timbren SES helps you avoid bottoming out and extends the life of your suspension
  • Control trailer sway: stabilizes the vehicle with unbalanced loads, in crosswinds or when passing heavy trucks
  • Control body roll: progressive-rate rubber springs resist lean in corners and add stability
  • Improve the ride: Aeon® rubber springs absorb road shocks and bumps, so towing doesn't have to mean poor ride quality
  • Economical and trouble free
  • Simple and easy to install
