This lightweight brake system is engineered to replace the heavy factory 1-ton brakes on GM Dana 60 front axles or any axle using GM-pattern kingpin knuckles with OE-style 8-lug wheel hubs. Designed for off-road performance, Ultra4 racing demands, and maximum stopping power, this kit significantly reduces unsprung weight while upgrading you to Wilwood’s competition proven 4-piston braking technology.

Reducing unsprung weight is one of the most effective upgrades for improving suspension performance, wheel control, and ride quality in off-road environments. This kit sheds 36.5 lbs compared to typical ¾-ton conversions, letting the shocks and springs do their job more efficiently. The 4-piston Wilwood calipers apply pad pressure evenly across the rotor surface, resulting in increased braking torque with better modulation—an essential advantage for Ultra4 speeds, rock crawling control, and heavy rigs on big tires. The oversized 13.5" rotor delivers improved leverage and increased thermal capacity, ensuring consistent stopping power in high heat, high load situations.
