Wilwood Caliper Dynapro 5.25in Lug Mount 1.75in Pistons .81in Disc - 120-9693
The DynaPro Lug Mount (DP) forged billet caliper represents the newest generation of calipers available as an upgrade or replacement for applications previously using the long-standing Dynalite model series. DP calipers combine pure race technology with several new exclusive Wilwood performance enhancements. A sleek profile with superior strength and a fully detail machined finish provide the performance and looks for competition or show.

The strength of the DynaPro is a combination of process and design. The DynaPro is stress-flow forged from premium grade billet. Stress-flow forging realigns the grain structure of the metal within the contour of the body design. This process produces a part with superior strength over parts simply machined from straight grained blocks of billet. The FEA generated body design incorporates a highly fortified radial transition that eliminates steps and shoulders between the piston housings and the bridges. Incorporating a radius in this critical area substantially increases resistance to deflection and caliper body separation under load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. Reductions in overall deflection, and the subsequent decreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The bottom line is a firm, responsive pedal with outstanding stopping power. The DynaPro is loaded with other enhancements for performance and wider application. The calipers feature Quick-E-Clip pad retainers that support a 7812 type brake pad from the top. Not only does it allow for fast pad service without caliper removal, the bottom pad supports have been removed to create a slimmer profile that can be more easily fitted into tight clearance applications.

Note:
  • Heavy wall stainless steel pistons are used to resist corrosion and slow the heat transfer from the pads. The heavy wall sectional thickness also provides additional strength against backside deflection to provide a firm pedal feel and efficient clamping, even at the high pressures generated by power boost systems.
  • For additional strength, all DP calipers can be fitted with a center bridge bolt kit to provide even greater resistance against body separation under high load. Center bridge bolts are included with all side inlet "SI" models and available as an upgrade option on all other models.

Who is Wilwood?

Willwood Engineering Inc. was formed back in 1977 by Bill Wood. The company is known for manufacturing a high-performance disc brake system. 

Throughout the years, the company has continuously improved itself, along with the ever-changing advancement in-vehicle technology. 

Today, the company had extended its wheel designs to supply brake components for various vehicles, including agricultural equipment, utility vehicles, motorcycles, four-wheelers, military vehicles, and even snowmobiles.

A Brake for Every Need

Wilwood has an extensive inventory of brakes parts for various vehicles. With over hundreds of brake calipers, master cylinder, and rotor designs, not to mention the tons of brackets, fitting, brake lines, and valves, it has the right kit for every vehicle application you can think of.

Engineered to Perfection

The company entails the most advanced technology and software in designing and manufacturing its products. They use a finite element analysis and multiple testing procedure such as a dynamic and cycle test that helps them replicate real-world conditions and adjust their design accordingly, making the necessary correction even before they manufacture the actual product

Using only the finest materials available, they can create a product that meets its clientele's expectation whether it's for street use or for race application.

Wilwood has also been ISO Certified, making it compliant to all mandated processing procedures set by the regulatory board.
