Description
Fits: 11-25 Chevrolet Silverado/GMC Sierra 2500/3500, 2WD or 4WD. Diesel catalog applications use 6.6L Duramax generations in these years.
This kit adds critical reinforcement to the idler support area of the frame, helping reduce flex and wear under load. Made from 1/4-inch plate steel, it improves steering stability and durability—especially on lifted or hard-used trucks. Designed to work with both factory and aftermarket idler supports.
