Timbren Industries GMRCK15S Rear Suspension Enhancement System with Aeon Rubber Springs

The Timbren Industries GMRCK15S Suspension Enhancement System is designed to eliminate rear sag, reduce sway, and improve roll stability when towing or hauling heavy loads. This rear suspension helper spring kit provides progressive suspension support that automatically adjusts to varying load conditions, keeping your truck level and stable whether you're towing an RV or hauling cargo in the bed.

Key Features:

• Patented Aeon hollow rubber springs deliver progressive spring rate that increases resistance as load increases
• 8,600 lb weight capacity for superior load-handling performance
• Cushions road shocks and absorbs impacts for a smoother, more comfortable ride
• No maintenance required—no air lines, compressors, gauges, or pressure adjustments needed
• Bolt-on installation using included steel mounting brackets and hardware
• Can be installed in under 30 minutes with basic hand tools
• Rubber springs remain in contact with frame but don't affect unloaded ride quality
• Each spring works independently to reduce body roll and handle off-center loads
• Lifetime warranty against defects in materials and workmanship

What's Included:

• Two Aeon SES hollow rubber springs
• Two steel mounting discs
• All necessary hardware for installation

Unlike air bag systems, Timbren SES kits require zero post-installation maintenance and provide true "set it and forget it" performance. The durable Aeon rubber construction ensures years of reliable service while improving vehicle handling, reducing trailer sway transfer, and maintaining proper weight distribution for safer towing and hauling.
