Wilwood 140-11857-R-U D8-6 Front Caliper Kit Red 6-Piston Aluminum

The Wilwood D8-6 Front Caliper Kit (140-11857-R-U) is a bolt-on brake upgrade engineered for direct OE replacement. Featuring a red powdercoated finish with an unpainted caliper body option, this kit pairs Wilwood's proven D8-6 six-piston fixed caliper design with DOT-compliant stainless steel braided brake hoses and semi-metallic brake pads — everything needed for a complete front brake caliper installation.

Key Features:

• 6-Piston Fixed Caliper Design — Delivers superior clamping force and more even pad wear compared to single-piston OE slide calipers
• Forged Billet Aluminum Body — Dramatically reduces unsprung weight vs. stock cast iron calipers (approx. 5.8 lbs per caliper vs. 12 lbs OE)
• Stainless Steel Pistons — Resist corrosion, bore pitting, and heat-related seal failures that are common failure points on original equipment calipers
• High-Temperature Seals — Competition-grade square-cut o-ring seals retained in machined grooves for long-term reliability
• Stainless Steel Bridge Wear Plates — Protect the caliper body from pad backing plate contact and gouging
• Piston Diameters: 1.880 / 1.380 / 1.250 in. — Mirrors factory caliper displacement for unchanged pedal feel and OE master cylinder compatibility
• Compatible Rotor Thickness: 1.250 in.
• Mounts in Stock Location — Over stock rotors, using original D8-style brake pads; fits snugly inside most 1967 and newer production wheels
• Red Powdercoated Finish — Durable color coat for a clean, performance appearance under the wheel
• Includes: Left and right D8-6 calipers, DOT-compliant stainless braided brake hoses, and semi-metallic brake pads

Kit Contents:

• D8-6 Front Brake Calipers (Left & Right)
• DOT-Compliant Stainless Steel Braided Brake Hoses
• Semi-Metallic Brake Pads (BP-10 / Smart Pad compound)

Important Note: Some early-style wheels, including certain 1965–66 OE steel wheels and select aftermarket replica alloys, may require a 3/16 in. or wider wheel spacer for proper clearance.

Sold as a complete front caliper kit. No mounting brackets included — designed to use OE factory spindles and stock rotor mounting positions. Manufacturer Part Number: 140-11857-R-U.
