Description: This KRYPTONITE Stage 3 Leveling Kit (KR11STAGE3BIL) is perfect for 2011 - 2019 GM 2500/3500HD trucks with 6.6L Duramax engines. It's designed to level the front of LML/L5P trucks up to 2 inches. The forged torsion keys are 25% stronger than OEM keys and offer a snug fit. You can easily lift your truck by 1 - 2 inches with the adjustable key, allowing for up to 32' wheels and tires without stressing the stock suspension. It's a more affordable alternative to traditional lift options. Features include a 2' front lift, stronger forged keys, a tight fit, compatibility with 32' tires, a smooth OEM ride, and no extra pressure on stock suspension. The kit includes upper control arms, sleeves, bushings, ball joints, hardware, leveling keys, and Bilstein front and rear shocks. Optional items are the KRYPTONITE CAM BOLT KIT and alignment pins. Installation instructions are available by clicking. Note: This kit levels the front up to 2 inches. Adjusting more than 2 inches over stock height may cause front shock failure. Some factory - preadjusted trucks like AT4, Z71, High country, and Denali HD may not follow the same height increase rules, and Bilstein shocks are not recommended for them. Kryptonite has improved access to grease fittings on upper control arms. The hardware kits include grease fittings and plugs for easy service. Bilstein Shocks have their own warranty, not covered by Kryptonite's Lifetime Warranty. Kryptonite offers a No Fine Print Lifetime Warranty against manufacturer defects, premature wear, or breakage, excluding Heim Joints. You must buy from an authorized dealer and register the warranty within 90 days of purchase.

Using the KRYPTONITE Stage 3 Leveling Kit is straightforward. First, make sure your truck is a 2011 - 2019 GM 2500/3500HD with a 6.6L Duramax engine. You can lift your truck 1 - 2 inches by adjusting the torsion key. This gives you enough space for up to 32' wheels and tires. When installing, follow the included instructions. If you click on the installation link, you'll find more detailed steps. Be careful not to adjust the lift more than 2 inches over the stock height, as this can cause the front shocks to fail. Also, if your truck is a pre - adjusted model like AT4, Z71, High country, or Denali HD, don't use the Bilstein shocks as they may lead to shock failure. For maintenance, regularly check the grease fittings on the upper control arms. The hardware kits come with grease port plugs, so make sure they're in place to keep the components well - lubricated. Remember, Bilstein Shocks have their own warranty, but Kryptonite offers a lifetime warranty on their steering and suspension components, excluding Heim Joints. Just make sure you buy from an authorized dealer and register the warranty within 90 days of purchase.
