PRODUCT DESCRIPTION
AT6 Lug Mount
Wilwood’s AT6 forged aluminum competition brake caliper is specifically designed, engineered, and built to withstand the rigors of off-road truck and buggy racing. The AT6 combines the latest materials and manufacturing process technologies into the most popular mounting configuration, built rugged enough for Baja. The caliper covers a broad range of competition categories in SCORE, BITD, Ultra-4, Pre-Runner, and all similar off-road and desert racing sanctions, and is ideally suited for both short course and long duration events. AT6 calipers feature a high-strength, lightweight forged aluminum lug mount body with popular 6.88” mounting centers. MIL-Spec Type III hard anodizing is applied to all surfaces on all models for increased wear and abrasion resistance. A robust bolt-together center bridge adds rigidity and provides for easy top-pad access. Thermlock® pistons are also available as an upgrade option.
