Hauling top-heavy loads like truck campers or salt spreaders demands maximum stability. This Timbren SES Severe Service Kit uses a single-convoluted Aeon® spring that resists weight more aggressively than classic kits. The result is a safe, stable ride that eliminates white-knuckle highway driving by drastically reducing sag, sway, and roll in top-heavy applications.

Part Number: GMRTT35D

Notes

Important Warning: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
