If you’re looking to upgrade your stopping power, this rear brake system is a solid choice. It packs a punch with a 6-piston Monoblock caliper that’s mounted to a 14-inch, 2-piece rotor that’s been slotted and drilled, plus it’s zinc plated for that extra bit of durability. The beauty of this setup is that it works seamlessly with your stock park brake assembly and brake hoses, so no need to mess around with complicated modifications. And don’t worry about dirt and moisture getting in—these calipers come with D.O.T. compliant dust and weather seals to keep everything in check.

Now, let’s talk about the fitment. This system is designed specifically for the 1960-1987 GM C-10 trucks that have a stock GM 10 or 12 bolt rear end and 6-lug wheels. With a bolt pattern of 6 x 6.500 inches, you’ll be good to go without any guesswork.

Why go for the Extreme+?

• It’s made right here in the USA with a forged MonoBlock caliper—no cheap stuff here.
• You get the same sleek look for both front and rear, which is pretty rare in the brake world.
• You'll need at least 18-inch wheels to fit this setup, so keep that in mind.
• Everything you need is included in the package, from hose adapters to fittings.
• The rotor comes pre-assembled, and the hat is made from 6061 T-6 billet aluminum, anodized black for that clean look.
• High-grade stainless hardware is used throughout, with captured nuts to make installation a breeze.

What makes the 6S Extreme+ caliper stand out?

• They can accommodate rotors from 13.5 to 16 inches, giving you some flexibility.
• Each caliper features a machined logo that’s hand-painted, adding a personal touch.
