• Lift height: ~3.5 inches of front lift to increase tire clearance and allow larger diameter tires with minimal trimming.
• Uni‑Ball upper control arms: heavy‑duty tubular arms equipped with teflon‑lined FK uni‑ball joints for 30%–35% more articulation and reduced binding, while preserving factory geometry.
• Premium joints & play: uni‑ball joints deliver smoother movement and enhanced durability under heavy loads and off‑road use.
• Rear lift via blocks: cast iron lift blocks provide reliable rear height; reinforced hardware ensures long‑term stability.
• Front shock relocation bracket: included to maintain compatibility with factory shocks and ensure proper alignment after lifting.
• Hardware bundle: complete kit with rear U‑bolts, mounting plates, spacers, and all necessary fasteners for a bolt‑on installation.
• Shocks not included: kit is designed to work with your existing shocks (or upgrade separately) and includes front shock extenders as needed.
• Rim and tire compatibility: supports up to 35" tires with minor trimming; rims should have 5"–5.5" backspacing or less to avoid rubbing the upper control arms.
• Durable, USA‑made: components are powder‑coated for corrosion resistance and built in the USA; backed by a limited lifetime warranty.
• Simple installation: designed for a straightforward bolt‑on process; no cutting or welding required; typical installs are done with basic shop tools.
• Fitment note: specifically designed for 2011–2019 GMC Sierra 3500 / 2011–2019 Chevy Silverado 3500 4WD (will not fit dually models).
