Wilwood Forged Billet Dynalite Internal Brake Calipers

Wilwood Forged Billet Dynalite Internal brake calipers are the next generation enhancement of the venerable Forged Dynalite Series calipers. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper's body. This removes the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The FEA-generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. Incorporating a radius in this transition area substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement tests have proven the Forged Billet Dynalite Internal to outperform all existing styles in this caliper class. Order the replacement model designed for your caliper application.

Wilwood Billet Superlite 6 Calipers

These billet SL6 series calipers integrate "Big Brake" style and Wilwood's latest technology. 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. The key to their superior performance is their extremely durable and efficient body design. It is the product of FEA computer solid modeling and stress analysis technology. Full-length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed-end bridges have produced the strongest caliper bodies ever built, according to Wilwood. When compared to open-bridge calipers that use tube or stand spacers between the body halves, the SL6 calipers' closed-end bridge design is measurably stronger, with less separation or deflection under load. Additional strength and deflection resistance come from the four high-strength steel end bridge bolts. A fifth center bridge bolt provides even more overall strength and easy access to the pads, without the need to remove the caliper from the mount. A unique 6-piston differential bore configuration provides balanced pad loading for even pad wear in sustained high-heat environments. The standard SL6 calipers feature one-piece stainless steel pistons. Stainless is used for its slow heat transfer properties and high resistance to corrosion.

Wilwood Billet DynaPro Calipers

These billet DynaPro calipers combine pure race technology with a new generation of Wilwood performance enhancements. Their sleek profile, superior strength, and durability in adverse conditions are easily adapted to a broad range of sports, rally, and off-road driving applications. Wilwood Billet DynaPro calipers feature a stress-flow forging that realigns the metal's grain structure within the contour of the caliper body. The FEA-generated, radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridge bolts. Structural deflection and volume displacement tests have proven the efficiency of this innovative design. All calipers are equipped with Wilwood's SRS stainless steel bridge plates. The SRS plates eliminate the bridge wear caused by pad gouging and extend the service life of the caliper body. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the vibration harmonics that contribute to squeal under braking.
