The Wilwood 140-10094-DR is a complete rear disc brake conversion built on the brand's Forged Dynalite Pro Series platform, designed for the large Chevy C10 rear axle housing flange with a 2.42" axle offset. Each kit pairs four forged billet Dynalite calipers, finished in red powder coat, with a 12.19" one-piece drilled and slotted rotor that houses an internal parking brake, plus BP10 Smart brake pads. The manufacturer positions the package for balanced braking on street/strip and show builds, and the integrated parking hat preserves a working handbrake instead of requiring a separate parking system. Buyers weighing it against a generic rear disc upgrade should note that offset and flange matching determine whether the rotor lines up with the caliper, and a matched kit like this avoids the spacer and alignment guesswork that universal setups often create.
Fitment is the first thing to verify. The manufacturer lists this kit for the Large Chevy C10 rear end with a lug-mount caliper, a 2.42" offset, and a 15" minimum wheel diameter, and its catalog marks the kit as 5-lug only. Published year ranges for C10 applications vary between sources, so confirm your truck's year, axle flange, and wheel clearance with the manufacturer before ordering, and review the wheel clearance diagram in the install instructions. Budget for the parking brake cable separately, since the manufacturer states its rear kits do not ship with parking brake cable hardware, though it offers a generic 330-9371 cable kit. If you are searching for a 2.42 offset C10 rear disc conversion with a drilled 12.19-inch rotor and integrated parking brake, this is the configuration you need to match, and the manufacturer's install sheets outline the prep and cable routing that make the job manageable for a careful DIYer.
No. The manufacturer specifies the Large Chevy C10 rear flange with a 2.42" offset and 5-lug pattern, so it is not a universal kit. The manufacturer advises verifying vehicle and wheel fitment before purchase, and year coverage varies between sources, so confirm your specific axle flange with the manufacturer.
No. The manufacturer states its rear kits are not supplied with parking brake cable hardware or adapters. It offers a generic 330-9371 parking brake cable kit that can be ordered separately for this application.
The manufacturer lists 15" as the minimum wheel diameter, and its kit information notes that some 15-inch wheels may fit. Check the wheel clearance diagram in the installation instructions against your specific wheel offset and backspacing before buying wheels or tires.
This is an intermediate-to-advanced rear end job, well beyond a simple pad swap, because the axle and housing flange must be prepared and the parking brake must be set up correctly. The manufacturer's assembly sheets call for verifying bearing outside diameter, housing flange mounting pattern, and axle stud pattern before assembly, along with removing nicks and burrs from both the housing and axle flanges and degreasing them. Stock bearing retainers come off the axles during the process. Route the parking brake cable with as few bends as possible, keeping bend radii at 6 to 8 inches or more, and restrain the cable so bends do not straighten under tension. Expect to plan for hydraulic line adapters, since the manufacturer notes that OEM rubber brake hoses generally cannot be adapted to Wilwood calipers. Given the measurement checks and cable work, an experienced installer or a shop with rear end experience is a sensible choice for many builders.
