Wilwood 120-16039 SX6R Radial Mount Caliper Right 6 Pistons

SX6R Radial Mount

The Wilwood SX6R/ST forged six piston caliper delivers heavy duty stopping power for the road racing. SXR/ST feature the ultimate heat protection using Thermlock® pistons and extreme durability in adverse conditions. Radial mounting, multiple options for piston volume, and a rotor diameter ranging to 15.00" give this caliper the versatility necessary to suit all types of heavy weight braking requirements.

The body of SX6R series is stress-flow forged from a premium grade aluminum alloy billet. Stress-flow forging realigns the metal's internal grain structure to flow within the contour of the caliper body. This process eliminates the stresses and interruptions to the internal grain structure that occur when machining a straight block billet. The results are a caliper with superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load.
