Timbren SES at Truck Army
Timbren SES (Suspension Enhancement System) rubber helper springs support your truck's rear suspension when you tow or haul. They use hollow rubber springs instead of air, so there's no compressor, no air lines and almost no maintenance. Timbren also makes Active Off-Road bump stops.
Why Timbren
- Progressive support: the springs engage as the load compresses the suspension, so the empty ride stays close to stock on most kits.
- No maintenance: nothing to inflate, leak or adjust.
- Bolt-on install: most kits replace the factory bump stop and bolt in.

Timbren FAQ
Timbren or air bags?
Timbren needs no maintenance and works automatically. Air springs let you adjust support for different loads. Pick Timbren for set-and-forget simplicity.
Does Timbren increase payload?
No. It improves stability and reduces sag, but your vehicle's payload and tow ratings don't change.
