2" 2020-2026 GMC Sierra 2500HD / 3500HD - Stage 4 Leveling Kit (with Fox 2.5 HTO Shocks) by Kryptonite

The Kryptonite KR20STAGE4FOX 2" Leveling Kit is engineered to safely and effectively lift the front of your GMC Sierra 2500HD/3500HD by up to 2 inches, providing a leveled stance and improved ground clearance. Designed to work seamlessly with factory suspension components, this system ensures OEM ride comfort without adding excessive pressure to stock parts.

This kit features forged torsion keys that are 25% stronger than OEM, providing a secure and durable fit that lasts the life of your truck. The adjustable torsion keys allow for 1 to 2 inches of lift, accommodating up to 34-inch wheels and tires while maintaining proper suspension geometry. For maximum strength and performance, the package includes Kryptonite upper control arms, which improve alignment stability and suspension durability.

Fox 2.5 Performance Series HTO shocks enhance handling and ride quality, utilizing precision-tuned damping technology for superior performance on and off the road. These shocks feature a massive 2.5-inch one-piece aluminum body, a 5/8-inch hard chrome shaft, and a Hydraulic Top Out (HTO) piston that reduces harsh top-out and enhances ride comfort.

Additionally, optional upgrades include the Kryptonite Cam Bolt Kit, recommended when replacing upper control arms, and Kryptonite Alignment Pins, which facilitate easier vehicle alignment by replacing worn or damaged factory pins. It is essential to note that adjusting beyond 2 inches over stock height may cause complete front shock failure, making it critical to stay within the recommended lift range for optimal performance and longevity.

Backed by Kryptonite’s No Fine Print Lifetime Warranty, this leveling kit is built to handle off-road adventures, towing, and daily driving while ensuring long-term durability. If it breaks, Kryptonite will replace it—no questions asked. To qualify for warranty coverage, products must be purchased from an authorized dealer and registered within 90 days of purchase.
