Wilwood's new limited offset FDLI Pro-Series Front Hub Kits for 73-83 Chrysler, Dodge, Plymouth: A,B,E, F & J Body disc offer disc brake upgrade solutions for OEM Disc spindles. We have completely redesigned our Pro Series line of brake kits using a larger 12.19" rotor and new forged aluminum hubs with the express purpose of maintaining the factory wheel position. This new kit does not widen the track from the original disc brake rotor assembly. Based on the venerable Forged Billet Dynalite (FDLI) caliper, these versatile kits are easily optioned to suit the braking requirements and style preferences for a daily driver, serious competition, or the most discriminating show enthusiast. Most vehicle applications require no modifications for installation. FDLI 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. Installation requires purchase of additional brake lines shown below.
