GMF55AWD Timbren Suspension Kit

Timbren Suspension Enhancement Systems work with your current suspension to keep the factory soft ride while unloaded and to engage when needed under load giving you the best of both worlds. 

  • Sold as Kit - Order 1 per Vehicle
  • Free Shipping
  • Carry Heavy Loads
  • Reduce Sway
  • Improve Roll Stability
  • Easiest to Use - Rubber cushions absorb road shocks and automatically adjust to uneven loads or road conditions.
  • Easiest to Maintain - There are no airlines or fittings to allow leaks. Simply bolt the kit on and you are set for a lifetime of trouble free suspension.
  • Easiest to Install - There are no holes to drill, no airlines to route and SES Kits can be installed in a matter of minutes using basic hand tools.  The softer ride quality of today's trucks and the mediocre suspensions found on most trailers can cause excessive trailer sway, instability and suspension settling.
  • Best Warranty in the Industry - Lifetime Warranty with Satisfaction Guarantee.
