SSBC’s rear disc-to-disc conversion kit

The SSBC rear disc brake conversion kit is marketed as offering meaningfully more braking power than the stock drum brakes. Treat any specific percentage figure as the manufacturer's own claim rather than an independently verified number, since actual improvement depends on pad compound and how the truck is used. This upgrade is a great choice for 1/2-ton Chevy/GMC trucks with larger wheels. It gives the truck a more modern appearance and braking capability, and mounts right up to the stock axle. It comes with thick-walled stainless-steel pistons and premium quality USA calipers. The kit even includes an integrated parking brake.

Installing an SSBC truck stop rear disc brake conversion kit is a simple process that will take an experienced mechanic about half a day. The installation does not require welding or pulling axle shafts. The kit comes with detailed instructions and includes all the necessary mounting hardware. It works with GM 2002-present Silverado/Sierra 1500 pickups with factory drum brakes. To install the kit, measure the rear axle’s drum flange to ensure that it will fit.

The SSBC rear disc brake conversion kit uses new rotors, calipers, and pads. It also includes stainless steel spacers and flex hoses to maintain a stock look. This upgrade kit will add more braking power and improve handling.

McGaughys Suspension is another option for GMC truck rear disc brake conversions. Their kits are designed to fit McGaughys drop spindles, lifted spindles, and stock spindles. They also reuse the factory calipers.

The Wilwood disc brake conversion kit will work with most 15-inch wheels. If your wheels are not large enough for these disc brakes, you can sand them down to gain clearance.

Confirm the exact current figure and your axle's measurement directly with Wilwood or the kit's spec sheet before ordering, since fitment details like this can change between kit revisions.

GM’s 1500s with the 5.3L have front discs

The 5.3L engines in GM’s 1500s come with drum brakes in the rear. The 6.2L version has discs all around and has a different EBC control module that is optimized for disc brakes. A good shop mechanic can easily install a disc/drum conversion kit. It’s easy and won’t break the bank. It requires only basic tools and doesn’t require welding or pulling axle shafts.

GM gave the Sierra and Silverado a mid-cycle refresh in the early 2000s, including a rear-end redesign and facelift similar to the HD trucks. Throughout the GMT800 generation, light-duty 1500 models kept the front disc/rear drum setup, while heavy-duty trucks continued to use four-wheel disc brakes.

As with any brake project, it's worth checking for open recalls or technical service bulletins on the specific truck before starting work, since issues like a weak vacuum brake booster can affect pedal feel and stopping performance even on a truck with healthy rotors and pads.

Whether the front discs need attention or the rear drums are finally being retired for a full disc setup, matching the kit to the truck's exact axle and spindle configuration is the key to a clean install.
