Wilwood Caliper-Billet DLS, 3.25" mt., 1.75" Pistons, .38" Disc
Billet Dynalite Single
Wilwood's Billet Dynalite Single utilizes close tolerance design and manufacturing techniques which results in the most rigid, lightweight and attractive caliper in the evolution of the Dynalite Single Series. Starting at 1.58 pounds, the Billet Dynalite Single is perfect for compact high performance braking as required in Open Wheel, Drag, Modified, Kart, Motorcycle and Off Road applications.
The two piston caliper is rigid, lightweight and holds a .49" thick, 1.1 cubic inch brake pad. Internal fluid passage and multiple bleed fittings permit right or left, front or rear mounting options with either 3.25" or 3.75" lug spacing, and will fit .25" to .38" thick rotors with diameters from 6.00" to 13.00". High temperature square piston seals control piston retraction while the stainless steel deep cup pistons reduce heat transfer from the pad to the brake fluid. Calipers accept 1/8-27 NPT inlet fitting and come standard with our exclusive re-usable pad retainer clip.
The Billet Dynalite Single comes standard with our black anodized coating, but is more spectacular in the brilliant polished version (shown at right) for a show car look. The machining versatility of our CNC equipment sculpts a part that enhances wheel and suspension detail while maintaining the close tolerance design attributes of the Dynalite Single Series.

Additional Notes
Wilwood's unique Thermlock® T1 Short Track Pistons is an optional feature on our Billet Dynalite calipers. The pistons incorporate a stainless steel shield and coated aluminum shell configuration to provide a highly efficient thermal barrier between the brake pads and the caliper body, seals, and fluid. Lower operating temperatures eliminate seal crystallization and localized fluid boiling while providing longer caliper service life through decreased distortion in the caliper body and piston bores.
