What you get up front

• FOX Factory Race Series 3.0 Coil-Over Shocks — Remote reservoir design with position-sensitive damping, Dual Speed Compression adjustment, and Internal Bypass technology for progressive damping control through rough terrain and high-speed runs.
• Heavy-Duty Tubular Upper Control Arms — 1.5" OD x 0.120" wall construction with indexed ball joint cup for caster correction, increased down-travel, and camber adjustment. Greaseable ball joints at one end, maintenance-free durometer bushings at the frame.

Out back

Fabricated steel lift blocks paired with longer u-bolts and a matching set of FOX Factory Race Series 3.0 shocks deliver the same Internal Bypass performance and damping zones as the front, ensuring consistent ride quality and bottom-out protection across the wheelbase.

Important notes

• FOX Internal Bypass shocks feature finned external reservoirs and Type III anodized aluminum bodies to manage shock fluid temperature and prevent corrosion.
