How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well.

(Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

Description

The Kryptonite Stage 4 Leveling Kit featuring Fox 2.5 HTO Performance Series shocks is the ultimate suspension upgrade for 2020–2026 GM HD trucks. Designed for performance, strength, and real-world reliability, this package delivers more than just ride height—it delivers capability.

Kryptonite’s forged torsion keys lift the front end up to 2 inches while maintaining OEM ride characteristics. The included boxed upper control arms correct suspension geometry and improve articulation. For damping, the Fox 2.5 HTO shocks utilize Hydraulic Top Out technology to control rebound and reduce harsh impacts—perfect for trucks running oversized tires or frequent off-road use.

This kit is engineered for easy installation, and every component is made to handle years of hard use without compromise.
