Crane Axle GM Dana 60 Wilwood Lightweight Brake Kit- 6 Piston
CA01051F-6
The Crane Axle Wilwood 13.5" Front Brake Kit for GM Dana 60 Kingpin Axles is designed to replace the heavy factory one-ton front brake system with a lightweight, high-performance package built around Wilwood six-piston calipers. Engineered for rock crawlers, Ultra4 race cars, prerunners, trail rigs, and heavy-duty street trucks, this bolt-on system delivers increased braking performance while reducing unsprung weight.
Featuring 13.5-inch vented rotors, forged six-piston calipers, machined 6061 aluminum brake hats, and laser-cut steel caliper brackets, this kit provides the stopping power needed for oversized tires and aggressive driving. The lightweight rotating assembly helps improve suspension response while maintaining compatibility with GM Dana 60 kingpin front axles using OEM-style 8-lug wheel hubs.
Includes:
- (2) Bolt-On Caliper Brackets
- (2) Wilwood Forged Dynalite 6-Piston Calipers
- (2) 13.5" Vented Wilwood Rotors
- (2) Crane Axle 6061 Aluminum Brake Hats
- (1) Set of Brake Pads

Tech Insight
1. Why upgrade to a six-piston brake system?
Six-piston calipers distribute clamping force more evenly across the brake pads, improving pedal feel, braking consistency, and heat management during repeated hard stops on heavy off-road vehicles.
2. What are the advantages of 13.5-inch rotors?
A larger rotor increases braking leverage, allowing more stopping torque for the same pedal effort. The vented design also helps dissipate heat during prolonged braking on the trail or at race speeds.
3. Why are aluminum brake hats used?
Machined 6061 aluminum hats reduce rotating and unsprung weight compared to traditional one-piece rotors. Lower unsprung weight helps the suspension react more quickly to uneven terrain while improving steering response.
4. Will this kit clear every wheel?
No. Six-piston calipers and 13.5-inch rotors require adequate wheel diameter and inside barrel clearance. Always verify wheel size, backspacing, and caliper clearance before installation.
5. Is this a complete bolt-on conversion?
Yes. This kit is designed as a bolt-on upgrade for compatible GM Dana 60 kingpin front axles using OEM-style 8-lug hubs and compatible kingpin knuckles. Always inspect wheel bearings, hubs, brake hoses, and master cylinder compatibility during installation.
