Timbren Industries GMRCK25D Suspension Enhancement System for GM 2500/3500

The Timbren Industries GMRCK25D Suspension Enhancement System is a rear suspension helper spring kit (also called a rubber helper spring or bump stop upgrade) for GM 2500/3500 trucks. It uses hollow rubber springs to give the rear suspension extra support when you tow or haul.

Key Features:

• Rated capacity: 8600 lbs
• Overall kit height: 6.25 inches
• Rear suspension support location, standard kit
• Patented Aeon® SES hollow rubber springs with a progressive spring rate. They push back harder as the load increases, which helps reduce squat, sway and roll.
• The rubber mounting spacers come assembled with the SES suspensions.
• The kit includes all necessary hardware.

What's Included:

• 2 Aeon® SES suspensions (hollow rubber springs)
• 2 integrated rubber mounting spacers, assembled with the SES suspensions
• All necessary hardware

These rubber springs are an alternative to air bags and add-a-leaf packs. After installation, leave a gap between the rubber spring and the mounting surface so the unloaded ride stays comfortable. The kit does not increase the vehicle's GVWR, so keep your load within the manufacturer's rating.
