DynaPro 6 forged billet calipers are combined with 12.19″ diameter rotors for this group of traditional non-ABS spindles on American muscle cars and vintage rods. The enhanced brake capacity and pad performance of the six piston calipers provide an intermediate level alternative to the bigger six piston kits. These kits compliment wheel, tire, and suspension upgrades on all types of custom show and high performance street / strip machines. A full range of caliper finishes and rotor designs enable the builder to personalize the style and optimize the brake performance for each individual application.
Wilwood’s Truck hats are precision machined from premium aluminum alloys for high strength and attention to minimized weight. Hats in this category feature threaded rotor mount holes for use with standard through-hole mount rotors. Truck Hats feature strengthening ribs on a flared bell configuration for big rotor brake kits on truck, SUV, and 4WD axles with either 6 or 8 lug configurations.
Combination hydro-mechanical Parking Brake calipers use hydraulic pressure from the master cylinder for stopping power, and an internal mechanical lock within the caliper for a parking brake. CPB kits are built primarily for front wheel drive vehicles, and select rear wheel drive axles that are not well suited for internal shoe style parking brakes. The calipers are coupled with oversized two-piece rotor assemblies with aluminum hats and high friction BP-10 compound pads. CPB kits provide the correct balanced brake performance and matching style to compliment front big brake upgrade kits.
Caliper wear plates are used to prevent pad “dig-in” and wear on aluminum bodies. Manufactured form stainless steel alloy for maximum abrasion resistance. This specific part number is used for Billet and Forged Superlite Calipers using .65” thick pads.
Forged Narrow Superlite 4R four piston calipers are combined with BP-10 compound pads and 13″-14″ rotors in this group of big brake kits for custom high performance street and show machines. This group of specialized kits for cars, trucks, and SUV’s retain full use of the OE parking brake, master cylinder output, and ABS where used. FNSL4R rear kits provide complimentary style and performance with 13″ and larger front brake upgrades in conjunction with wheel, tire, and suspension upgrades. Optional caliper finishes and rotor designs enable the builder to match style and performance on all applications.
Wilwood’s GT & GTB 72 Curved Vane Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood. Every Spec 37 rotor is precision machined to less than .001″ run-out, flatness, and parallelism. Combined with our proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest braking available. GTB rotor have additional black e-coat finish applied for applications where corrosion resistance is concern.
Wilwood’s GM style proportioning valve is a direct replacement for 1978 and newer General Motors vehicles equiped with front disc / rear drum brakes.Manufactured from high quality aluminum and coated with a durable black anodized finish. Line connections for the valve, if mounted in the OE location, Will allow the original lines to connect directly to the valve. If mounted in a non-OE location, fluid lines may have to be modified. This also does allow usage in other non-GM vehicles. This proportioning valve offers: 63% pressure reduction (rear) after 350 PSI knee point. A 30 PSI delay rear-to-front circuit and Circuit failure sender activation at 50 ± 10 PSI. A Recommended maximum operating pressure: 2000 PSI. Non-adjustable front-to-rear proportioning (knee point, rate, etc.) and Anti-dive or metering delay valve: Enables rear brake pressure to build momentarily before front brake pressure builds.
Wilwood’s Tactical Extreme TX6R Big Brake kits are ultimate in braking performance for Truck, SUV and Armored Vehicles. Using TX6R radial mount six-piston calipers and massive 15.00” to 16.00” GT-60 directional vane Spec-37 alloy rotors, these kits deliver consistent stopping power and extreme duty durability under sustained high heat with this ready to bolt-on kit. The calipers are volume matched for compatibility with original equipment power brake system output. Kits include radial mount caliper brackets, and all the necessary hardware to complete the installation. Braided stainless steel flex lines will need to be purchased for some applications.

Wilwood High-Volume Aluminum Master feature high pressure die-cast bodies from high-grade aluminum. Wilwood. High-Volume Master Cylinders have the highest fluid capacity of any integral reservoir design. With a total capacity of 8.2 ounces, there is at least 26% more fluid volume than other brands. . With 1-7/16″ of piston travel, it offers extra margin when used with large piston calipers. Heavy duty internal springs provide fast retraction. Formed steel lids with bellows type gaskets keep the moisture out. Wilwood master cylinders use common dimensions for flange or side mounting and a 1/8-27 NPT outlet port.
Wilwood’s Tru-Bar balance bar system is now available in a Reverse Swing mount pedal with a 5:1 ratio. Tru-Bar pedals utilize a fixed trunnion bearing in the pedal arm, with spherical rod-end bearing pushrod attachments. They provide ultimate precision, control, and adjustment of the brake bias on race prepped vehicles. The new Tru-Bar pedals utilize the same chassis and master cylinder mounting as all Wilwood balance bar style pedals. A stronger and larger diameter 7/16-20 bar provides quicker adjustment and features a shouldered 3/8″ diameter end to attach the standard remote adjuster cable to deliver professional, championship caliber performance. Wilwood’s Tru-Bar balance bar utilizes a fixed trunnion bearing in the pedal arm with spherical rod ends at the pushrod connections. It provides the ultimate in precision bias adjustment, control, and fine tuning on race prepped vehicles equipped with twin brake Master cylinder systems and proportionately sized calipers.
