120-14850-BK - Product Description

AT6 Lug Mount

Wilwood’s AT6 forged aluminum racing caliper is designed, engineered, and purpose built to endure the rigors of off-road truck and buggy racing. The AT6 combines the latest technologies in manufacturing materials and processes in the most popular mounting configuration built “tough enough for Baja.” The caliper covers a wide range of racing classes in SCORE, BITD, Ultra-4, Pre-Runner, and all similar sanctions of desert and off-road competition, and is well suited for both short course and endurance length events. AT6 calipers feature high-strength, lightweight forged aluminum lug mount body with the popular 6.88” mount centers. MIL-Spec Type III hard anodizing is applied to all surfaces on all models for long wear and abrasion resistance. A massive bolt-in center bridge support adds stiffness and top-side pad access. Thermlock pistons are also available as an upgrade.

Six-piston, progressive differential bore configuration provides even pad wear through balanced loading. Stainless steel pistons reduce heat transfer and resist all corrosion. Internal seal-in-bore design provides controlled retraction without the issues common to external boots. Internal damper springs reduce deflection induced pad knock-back. Replaceable stainless steel, spring loaded bridge abutment plates. Uses large volume type 7516 pads. Also available with gloss red or black
