Verified Fitment & Application Support

This product is selected for proper fitment and compatibility with the listed engine application. Our team is available to assist with fitment questions, installation considerations, and supporting components to ensure a smooth install and reliable performance.

The Timbren SES rear suspension enhancement system for the 1999 Chevrolet Express 2500 replaces the factory bump stops with Aeon hollow rubber springs that carry load as it is applied. Because the springs work progressively, the kit controls sag, sway and body roll under load without stiffening the ride when the vehicle is empty.

Key Features

  • Aeon hollow rubber springs with a progressive spring rate: the more weight applied, the harder they work
  • Automatically adjusts to uneven loads and road conditions
  • No air lines, fittings or compressor to leak or maintain
  • Bolt-on installation in minutes with basic hand tools, no drilling
  • Does not change unloaded ride height or ride quality
  • Laser-cut, precision-bent, powder-coated steel brackets
  • Timbren Lifetime Warranty

Fitment

  • 1999 Chevrolet Express 2500

Adding helper springs does not increase the vehicle GVWR set by the manufacturer; do not exceed it.
