What you get up front

• Top-mounted strut spacers — raise the front end while keeping the strut assembly intact for smoother operation and easier service.
• 1/4-inch steel crossmembers — laser-cut for perfect fit, engineered for rigidity and ground clearance on and off-road.
• CNC-machined steering knuckles — correct caster geometry at the new height so your truck steers straight and tracks true, with ESC system compatibility preserved.
• Replacement tie rod ends — work with the new knuckles to maintain steering angles and suspension geometry.
• Front skid plate — 1/4-inch steel protection that bolts to the crossmembers, guarding the undercarriage.
• Sway bar drops, bump stop extensions, brake line brackets, CV spacers, and hardware — everything needed for a complete, bolt-together front assembly.

Out back

Heavy-duty lift blocks replace the factory units, raising the rear 3 inches and leveling your stance. New u-bolts and shock relocation brackets keep your Adaptive Ride Control system functioning without fault codes, while retaining full ride quality and load capacity.

Important notes

• This kit is Adaptive Ride Control only — not compatible with air suspension or other option packages.
• Maximum tire size is 33 x 12.5 — exceeding this risks rubbing and geometry issues.
• Front lift is achieved via cross member and strut spacer; rear uses a block method.
• All ESC and ARC system components are recalibrated during install to prevent fault codes and ensure proper function.
