The Kryptonite KRFD17STAGE1BIL Stage 1 Leveling Kit with Bilstein Shocks is a high-quality suspension upgrade designed to improve the stance and ride quality of 2017-2025 Ford F-250/F-350 Super Duty 4x4 trucks. This complete kit provides an additional 1.5" of front lift while maintaining proper suspension geometry and ensuring smooth handling both on and off the road.
With this kit, you can install up to a 35"x12.5" tire on a 9" wide wheel with 4.5" backspacing with little to no trimming. A 37" tire can also be used with additional fender and front bumper clearance modifications. The included 2° caster correction shims help maintain proper alignment, reducing wear and optimizing drivability after lifting. Equipped with Bilstein 5100 Series extended-length shocks, this kit enhances ride stability and performance by providing superior damping control. The 1.5" bottom-mounted coil spacers, bump stop spacer kit, and brake line drop brackets ensure secure and reliable installation while preserving suspension integrity. The precision CAD-engineered billet aluminum spacers, durable black finish, and high-strength Grade 10.9 hardware contribute to exceptional durability and long-term reliability.
Manufactured in the USA, this leveling kit is built to withstand harsh conditions, making it a reliable choice for truck owners looking to enhance their vehicle’s stance and performance without sacrificing ride quality.
