Wilwood's new DP-DB Pro-Series Front Hub Kits offer disc brake upgrade solutions for OEM spindles. We have completely redesigned our Pro Series line of brake kits using a larger 11 in rotor and new forged aluminum hubs with the express purpose of maintaining the factory wheel position. Based on the venerable Forged Dynapro Dustboot caliper, these kits were developed for applications or locations that require or prefer a dust-sealed piston. Dust-booted aluminum pistons provide added protection against road or track born dirt and debris on low to intermediate temperature range applications that may also operate in harsh environments. Most vehicle applications require no modifications for installation, and provide plenty of clearance inside popular 15 in wheels. DP-DB Pro-Series kits can be used with either manual or power boost master cylinders. Kits come complete with calipers, rotors, hub assembly, brackets and hardware. Kit installation requires purchase of additional brake lines shown below.
