If you are building a 1963–66 Chevy C10 and want to upgrade the stance, brakes, steering, and suspension all at once, CPP’s Grand Slam Kit, part number 6366GSK-55213, is a solid package to look at.
This kit is designed to give the truck a better stance and a more modern feel without having to piece together a bunch of separate components. It includes CPP’s modular 2.5" drop spindles, 13" front big brake kit, drilled and slotted rotors, twin-piston 52MM calipers, power brake components, springs, shocks, steering parts, ball joints, and the hardware needed to bring the front end together. One of the biggest advantages of this kit is that it is more than just a brake upgrade. A lot of C10 owners start with brakes, then realize the steering, suspension, springs, shocks, and worn front-end parts also need attention. The Grand Slam Kit helps cover all of that in one package.
The modular 2.5" drop spindles help lower the truck while keeping the suspension geometry in better shape than lowering with springs alone. The kit also allows you to choose different front and rear spring drop options, so you can set the truck up with the stance that fits your build.
The 13" front big brakes are a major upgrade over the factory drum brake setup. With larger rotors and twin-piston calipers, the truck should have a much more confident brake feel, especially if you are running more horsepower, larger wheels, or just want the truck to feel safer and more controlled on the street. A few things to keep in mind: wheel fitment should always be checked, especially if you are still running factory drum brake wheels. CPP also recommends checking with them if your truck has leaf springs or a non-standard rear setup.
Overall, the CPP 6366GSK-55213 Grand Slam Kit is a good option for anyone wanting to give a 1963–66 C10 a better stance, stronger braking, and a more complete front-end upgrade in one package.
