Wilwood 120-14851 AT6 Forged Aluminum 6-Piston Disc Brake Caliper

The Wilwood AT6 forged aluminum racing caliper is purpose-built to withstand the extreme demands of off-road truck and buggy competition. Engineered for durability and consistent braking performance, this caliper is designed to compete across a wide range of sanctioned events including SCORE, BITD, Ultra-4, Pre-Runner, and all similar desert and off-road sanctions — performing reliably in both short course and endurance-length races.

Key Features:

• Six-Piston Progressive Differential Bore Configuration: Promotes even pad wear through balanced loading across all six pistons
• Stainless Steel Pistons: Reduces heat transfer to brake fluid and resists corrosion in harsh off-road environments
• Internal Seal-in-Bore Design: Delivers controlled piston retraction without the seal degradation and contamination issues associated with external boots
• Internal Damper Springs: Minimizes deflection-induced pad knock-back for more consistent pedal feel and braking response
• Replaceable Stainless Steel Bridge Abutment Plates: Spring-loaded design allows for quick pad changes and extended caliper service life
• Type 7516 Large Volume Pad Compatibility: Accepts high-capacity pads suited for sustained racing use
• Available Finishes: Also offered in gloss red or gloss black anodized finishes

The Wilwood 120-14851 AT6 caliper is the choice of serious off-road racers who demand reliable, fade-resistant braking performance under the most punishing conditions. Its forged aluminum construction keeps weight to a minimum while maintaining the structural integrity required for desert racing, rock crawling, and high-speed off-road events.
