AERO6 calipers were designed for the specific purpose of providing big-capacity braking with large-diameter rotors for heavy-weight and extreme-duty vehicles. These kits are for the popular 1988 through 1998 Chevrolet & GMC C1500 & C2500 Trucks using Wilwood’s new 1-piece Iron Drop Pro Spindles.

AERO6 Big Brake Kits provide big stopping power for towing, off-road, and enhanced braking with wheel and tire upgrades. Kits are fully compatible with OE master cylinder output and ABS function. Directional staggered vane 14.00” rotors provide maximum cooling for sustained high heat durability. This kit contains hubs with 5 x 4.75” and 5 x 5.00” bolt circle.

Forged Narrow Superlite 4R rear disc kits provide the ultimate Big Brake solution for popular muscle car rear axles that require a parking brake. FNSL4R four-piston calipers, 13” or 14” two-piece rotors, and high-performance BP-10 compound pads provide optimized and balanced braking to compliment front big brake upgrades on all types of custom, show, and high-performance street machines.

The neatly hidden internal shoe system provides a clean installation with superior static holding power for parking. Optional caliper finishes and rotor designs allow builders to personalize the style and performance for every application.
