3 Inch Lift Kit | Vertex | Chevy/gmc 2500hd/3500hd (20-26)

Built for Chevy and GMC HD truck owners who want aggressive stance and tire clearance without sacrificing driveline geometry, this 3-inch lift kit combines bolt-on simplicity with engineered performance. Rough Country's Vertex platform delivers optimized axle geometry through differential drop brackets, keeping your driveshaft angles correct while you run 33"–34" tires and gain the ground clearance that transforms your truck's presence.

Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.

What's included

• 3-inch Kit Box (no shocks) — Rough Country's complete lift platform engineered for your 2500HD or 3500HD, shipping without shocks so you can pair it with N3 nitrogen-charged units or upgrade to Vertex reservoir shocks.
• Red Forged Upper Control Arms — One-piece aluminum arms with pre-installed POM ball joints for articulation and durability; the bold red finish option distinguishes your build while eliminating welded weak points.
• Vertex 2.5 Front Coilovers (pair) — Paired nitrogen-charged reservoirs maintain consistent ride quality and handling under load across all driving conditions.
• Vertex 2.5/3.5–7.5 Rear Coilovers (pair) — Adjustable rear travel accommodates payload and setup preferences while preserving driveline angles via differential drop brackets.
