Performance Online is definitely tearing it up in the area of brakes and suspension.  These serious performing kits are available for 1960-70 Chevy – GMC C-10 and C-15 trucks.  The deluxe version for the (POL) drop spindle disc brake wheel kit is shown above.  This is exclusively available for the 1963-70 model GM truck, while the 60-62 GM model trucks utilize a direct fit spindle not utilizing the ball joints, tie rod ends and adjusting sleeves shown above.  “This is a very good selling item for us” says CEO Jim Chadick.  “Considering that the rotor diameter is already at the 12-inch benchmark and the system utilizes large GM D-52 calipers.  Our reports show this kit as the most performance for your dollar.”  There are many options to the brake and suspension package shown.  Options include: drilled & slotted brake rotors, stainless steel braided brake hoses and even Wilwood multiple piston calipers can be added as an upgrade option.  Standard features are stock height or 2.5″ drop Western Chassis spindles, high quality 5 or 6 lug HD rotors and high performance tie rod adjusting sleeves.

Original Drum Brake Assembly

High Quality Western Chassis Spindles

Power Brake Kit Upgrade

High Quality Replacement Splash Shields

Western Chassis Stock & Drop Spindles

drop-spindles-high-qualityHere is a bit of truckin’ history! Western Chassis has just located these original design plates from the former owner of Western Chassis.  A far cry from how the manufacturing process is done today, but the design is still very close to the spindles Western provides today.  Notice the date stamp, October 1981. All spindles meet the ASTM standards for ductile iron castings.
