Calipers

We are one of Wilwood's larger independent dealers. Although we do not stock the all the calipers in Wilwood's catalog, we can supply them at a resonable price by having them shipped direct to you if you are located in the lower 48 states. For expedited service please specify when you are in the check out portion of the shopping cart. Technical Questions?
 
The Dynalite caliper series has widespread application over many forms of motorsports. It serves as the base model in the majority of Wilwood's Bolt-on Disc Brake Kits. The latest applied developments and innovations in caliper design and manufacturing processes have resulted in substantial improvements in strength and performance over all comparable caliper models. Comes black anodized (F) or polished (P).
 
The DynaPro four-piston radial mount caliper combines pure race technology with a new generation of Wilwood performance enhancements. Its sleek profile, superior strength, and durability in adverse conditions are easily adapted to a broad range of sports, rally and off-road driving applications. For more information click here.
 
Superlite 6 Caliper 3.5" Lug Mount. The billet SL6 series integrates "Big Brake" style and Wilwood's latest technology into the traditional 3.50" centered lug mount Superlite caliper category. Each caliper is precision CNC machined from high strength billet into three specialized configurations that cover a broad range of competition and sports driving applications.
 
Superlite 6 Caliper 3.5" Lug Mount with Thermlock Pistons. The billet SL6 series integrates "Big Brake" style and Wilwood's latest technology into the traditional 3.50" centered lug mount Superlite caliper category. The SL6/ST models feature Wilwood's exclusive Thermlock® pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.
 
Superlite 6 SL6R Caliper Radial Mount. The Billet SL6R series adds the versatility and convenience of radial mountng to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. These calipers integrate "Big Brake" style with Wilwood's latest technology to generate big stopping power in extreme environments over a broad range of vehicle applications.
 
Superlite 6 SL6R Caliper Radial Mount with Thermolock Pistons. All SL6R/ST models feature Wilwood's exclusive Thermlock pistons. This multi-piece piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade.
 
The Forged Billet Superlite (FSL) is the newest innovation to this series from Wilwood. New and adaptive technologies have been applied providing substantial improvements in strength, fluid volume displacement, and overall performance.
 
.Superlite 4 Caliper 3.5" Lug Mount. The billet SL4 and SL4/ST calipers incorporate Wilwood's latest technology in a conventional 3.50" centered lug mount design. This caliper series has been structurally designed for high clamping efficiency and low deflection in a body width compatible with all wide 5 and 5 x 5 style hubs. It is a direct replacement for all other Superlite style calipers.
 
Superlite 4 SL4R Caliper Radial Mount. The Billet Superlite 4R/ST is an extremely rigid, four piston, radial mount design that incorporates Wilwood's latest technology in brake system heat management. With its small piston volumes and large pad capacity, it is ideally suited for rear brake applications in severe duty oval track and road course competition.
 
Wilwood's GM III caliper represents the latest refinements in caliper design and manufacturing through the use of solid modeling and stress simulation programs. The result is the most rigid, highest torque, lightweight aluminum caliper in its class. Direct replacement for the 70-77 GM caliper.
 
Wilwood's GM Metric Caliper is a direct replacement for the 1978 and later D154 type GM metric caliper. Weighing in at a mere 2.97 pounds, it provides a substantial weight savings over cast iron OE calipers.
 

GN III and GN III/ST Caliper Features:
High strength, low deflection, and superior stopping power. Each GN III is manufactured from a precision casting using a tight grained, high-density aircraft alloy. It is a two piece, closed bridge design with grade 8 thru-bolts and external stiffening ribs. The GN III utilizes a unique six-piston configuration that generates high clamping force with balanced loading for extremely even pad wear. The 1.75" / 1.38" / 1.38" bore pattern contains a total of 5.44 square inches of effective piston clamp area. This makes the GN III one of the largest calipers available. The caliper bridges are fitted with stainless steel plates to reduce wear and provide smooth pad operation. Dual center bridge bolts add to the overall caliper strength and provide positive retention for the top loaded pads. Dollar for dollar, this combination is unmatched for high strength, low deflection, and superior stopping power.

 
The GP 320 billet caliper has been FEA developed and fully CNC machined. This yields the highest possible clamping efficiency without deflection while providing balanced pad loading, all from a compact, lightweight four piston design. Corrosion free 1.25" diameter stainless pistons resist heat transfer from the pads to reduce thermal distortion in the piston bores, extend seal life, and reduce fluid temperatures to help prevent heat generated pedal fade. Quick-Clip pad retainers allow fast service of the top loaded pads 3.50" centered mount is easily adapted to common brackets provided by the spindle manufacturers. PolyMatrix “H” compound brake pads compliment this caliper and have a smooth, predictable engagement at all temperatures with continued positive response as pedal pressure is increased or brake temperatures rise. These pads yield a long wear rate and are fade resistance to over 1,300° F.
