BlackOut Series Rear Disc Brake Conversions
Match the rear braking system to your BlackOut build with vehicle-specific and rear-end-specific disc brake conversions. Find options for Chevy C10 and 1500 trucks, Bel Air and Impala, GM 10- and 12-bolt rear ends, and Ford 8- and 9-inch applications.
BlackOut Rear Disc Brakes by Rear-End Configuration
With rear disc brakes, the badge on the fender only tells part of the story. The axle housing underneath the vehicle determines where the caliper mounts, how the rotor sits, and which bearing and flange dimensions the conversion must accommodate.
That creates several distinct paths within the BlackOut collection. C10 applications divide between 6-lug and 5-lug truck setups, later Chevy 1500 models use their own configuration, and Bel Air and Impala systems are built around the OEM rear end.
Swapped rear ends open the category further. GM 10- and 12-bolt assemblies can use dedicated 11-inch BlackOut packages with D154-style calipers, letting the brake conversion follow the axle rather than the vehicle it came from.
Baer Track 4 systems push that same axle-first approach into larger 12-inch performance brakes, with separate solutions for GM 10-/12-bolt and Ford 8-/9-inch rear ends. At that point, axle geometry and wheel clearance define the installation limits, while the BlackOut finish keeps the final brake package visually consistent.
FAQ
How do I choose the right BlackOut rear disc brake conversion kit?
Start by identifying the rear end currently installed in the vehicle. Confirm the axle housing and flange, bearing configuration, axle offset, wheel bolt pattern, and available wheel clearance. Vehicle year and model are useful for vehicle-specific kits, but rear-end specifications become especially important if the axle assembly has been changed from the original factory setup.
Which BlackOut rear disc brake kit fits a Chevy C10 truck?
It depends on the truck year and wheel bolt pattern. This collection includes a 6-lug BlackOut rear conversion for 1963-70 Chevy C10 trucks and a 5-lug version for 1971-87 C10s. There is also a separate 5-lug rear conversion for 1988-98 Chevy 1500 trucks. Confirm the rear end and bolt pattern currently installed before choosing by model year alone.
What BlackOut kit fits a GM 10- or 12-bolt rear end?
POL offers an 11-inch BlackOut rear disc brake conversion specifically for GM 10- and 12-bolt rear ends. It uses black powder-coated D154 GM ratcheting calipers and dual-pattern rotors with 5x4.75-inch and 5x4.5-inch bolt patterns. The application can cover rear ends used in vehicles such as Camaro, Chevelle, Nova, and other GM classics.
What is the difference between the 11-inch and 12-inch BlackOut rear brake kits?
The collection includes standard BlackOut conversions using 11-inch rotors as well as 12-inch Baer Track 4 performance systems. The Baer configurations provide a different performance-oriented brake package and are available for selected GM 10/12-bolt and Ford 8/9-inch applications. Rotor size also affects wheel clearance, so the larger system should be chosen according to the complete vehicle setup rather than rotor diameter alone.
Are BlackOut rear disc brake kits available for Ford rear ends?
Yes. The collection includes a 12-inch Baer Track 4 rear disc brake conversion for 1964-66 Ford 8- and 9-inch small-bearing rear ends. Because Ford rear ends are available with different housing ends, bearings, and axle configurations, confirm that your rear end matches the small-bearing specification required by the kit.
Will a BlackOut rear disc brake conversion fit my existing wheels?
Fitment depends on more than wheel diameter. Rotor size, caliper dimensions, wheel offset, spoke design, inner-barrel clearance, and wheel bolt pattern can all affect compatibility. This is particularly important with the 12-inch Baer Track 4 systems. Check the clearance requirements for the exact kit before assuming an existing wheel will fit.
What else should I check before converting my rear brakes to discs?
Consider the entire braking system, including the existing front brakes, master cylinder, proportioning valve, brake lines, and parking brake arrangement. Converting from rear drums to discs changes the hydraulic requirements of the system, so the front and rear components need to work together. Also confirm what is included with the individual BlackOut kit and whether any additional hydraulic or parking brake components are required.
