High-Strength Support Frame Gusset

If you’re putting serious stress on your truck’s front end—whether it’s from oversized tires, tough trails, or heavy towing—frame flex around the idler support is a common weak point that can lead to premature steering issues. The Kryptonite KRGUSSET11 Idler Support Frame Gusset is built to reinforce that vulnerable area and give your 2011–2025 Silverado or Sierra HD the rigidity it needs under pressure. Crafted from beefy 1/4-inch plate steel and engineered specifically for heavy-duty GM trucks, this gusset braces the frame at the factory idler location where flex can wreak havoc over time. It bolts directly to the idler support, while the frame side is intended to be welded on for maximum strength and long-term performance. Whether you're running stock geometry or upgraded components, this gusset integrates seamlessly with both factory and aftermarket idler supports.
