Wilwood AERO4 Rear drum-to-disc big brake kit conversions from Accesspeed are based on the popular motorsports-proven AERO4R caliper and Spec 37 rotors. Wilwood’s complete bolt-on brake kits provide an upgrade to make trucks safer with improved stopping power and include an internal parking brake assembly and parking brake cable connection kit to maintain the original feature. Experience more clamping force, better thermal capacity, and improved pedal feel for more confident braking in daily street performance to heavy-use applications including hauling, towing, off-road, and commercial workloads. These brake kits are designed to complement Wilwood front brake kits, and they are engineered to be compatible with factory ABS and OE master cylinders. The 14” proprietary Spec 37 iron alloy rotors come in a 5 x 5.00” lug pattern and feature 72 curved vanes.  Wilwood’s BP-10 street performance brake pads and premium-grade hardware are included. Calipers come in gloss red or black powder coat and 24 optional colors (additional charges apply).
