This pair of lower bump stops is specifically designed for 2001 - 2010 GMC trucks with a 6.6L Duramax engine (models 1500HD, 2500HD & 3500). Over time, regular bump stops can fail as the suspension contacts them during operation. Once they start to fail, you'll experience a rough ride on big bumps, and the lower control arm might hit the bump - stop mount, potentially damaging the suspension. Kryptonite advises replacing the bump stops as soon as they crack to safeguard your suspension components. Part number is K1426. It comes with Kryptonite's No Fine Print Lifetime Warranty, which covers any manufacturer defects, premature wear or breakage. Just note that the warranty excludes Heim Joints, and you must buy from an authorized dealer and register the warranty within 90 days of purchase.

Using these bump stops is straightforward. Simply replace your old, worn - out bump stops with these new ones. When you notice your truck having a rough ride on big bumps or see cracks on the bump stops, it's time to install these. As for maintenance, there's not much to do. Just regularly check the bump stops for any signs of damage or excessive wear. If you see any issues, replace them right away. Remember, for the warranty to be valid, buy from an authorized dealer and register it within 90 days of purchase. And don't expect the warranty to cover Heim Joints.
