Key Features

• CNC-machined ductile cast iron steering knuckles that maintain ESC system compliance and correct steering geometry at ride height
• Multipoint differential relocation brackets to secure the front axle and improve CV angles
• Rear lift block that retains factory ride quality and load capacity
• Choice of NX2 Nitro or FOX 2.0 Performance Series gas shocks
• Factory Protection Plus drivetrain warranty included
• Clearance for up to 33" tires

Shock Options

NX2 Nitro Series: Nitrogen-charged, twin-tube design with 10-stage velocity-sensitive valving, dual-welded ends for added strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.

FOX 2.0 Performance Series: 2-inch Impact extruded aluminum body with internal floating piston (IFP) monotube design, CNC-machined 6061-T6 aluminum mounting ends, a 5/8-inch hard chrome plated heat-treated alloy steel shaft, race-developed high-flow piston, application-specific valving, and a long-lasting clear anodized finish.

Track Width Options

This system is available with two knuckle designs. The standard knuckle widens track width without affecting turning radius. The narrow track knuckle reduces total track width change by about 1.5" overall but slightly increases the turning radius.
