Wilwood 120-14764-SI BNDLR 4-Piston Radial Mount Caliper Anodized 1.88in 0.38in

Vehicle Fitment

• Universal - Compatible with Sprint Car, Midget, and Inboard racing applications using 4.75" center radial mount and 0.38" wide rotors
• Can be directly mounted over studs on a 4.75" center mounting, or used with a radial mount bracket kit in place of a tab mount caliper
• Compatible with short track, late model, modified, Sprint, Midget, off-road, and road racing applications

Fitment Notes

• Designed specifically for 0.38" wide rotors - not compatible with 0.81" or 1.00" rotor widths; confirm rotor thickness before purchase
• 4.75" center radial mount - confirm your spindle or bracket uses this mounting center before ordering
• Side inlet fluid port location - confirm brake line routing compatibility with your specific chassis before installation
• Uses 7816-style brake pads (0.63" thick) - confirm pad compound selection for your application
• Sold individually - two required for a complete axle
• Professional installation by a qualified brake technician is strongly recommended

Features

• Billet CNC-machined aluminum body - compact and lightweight design starting at 3.00 lbs., ideal for Sprint and Midget inboard applications
• Radial mount configuration - more rigid than traditional tab mount designs for superior brake feel and consistency
• Spacer-less single split bridge design provides maximum structural rigidity and visual cleanliness for 0.38" rotor applications
• Center bridge bolt adds overall caliper strength and provides positive retention of top-loaded pads
• Four stainless steel cup pistons (1.88" diameter) deliver strong, consistent clamping force across the full pad face
• Internal fluid ports eliminate external fluid tubes for a cleaner installation and reduced failure points
• Two corner bleeds and outboard side inlet in the correct position for standard inboard mount applications
• Stainless steel anti-rattle wear plates on bridges reduce wear and provide smooth, rattle-free pad operation
• Type III Mil-Spec hard anodized finish - durable aluminum-oxide ceramic coating that resists bore wear and surface abrasion

Product Description

The Wilwood 120-14764-SI is a Billet Narrow Dynalite Radial Mount (BNDLR) four-piston brake caliper in Type III hard anodized silver, engineered specifically for Sprint Car, Midget, and Inboard competition applications requiring a 0.38" wide rotor. The BNDLR series has grown steadily in popularity in Sprint and Midget inboard applications thanks to its compact, lightweight construction - starting at just 3.00 lbs. - combined with the superior rigidity of a radial mount configuration over traditional tab mount designs.

The spacer-less single split bridge body maximizes structural rigidity for the narrow 0.38" rotor application, while the center bridge bolt provides positive retention of the top-loaded 7816-style pads. Four stainless steel cup pistons at 1.88" diameter deliver strong, even clamping force. Internal fluid ports eliminate external tubes entirely, and the side inlet with dual corner bleeds is positioned for correct installation in a standard inboard mount application. The durable Type III Mil-Spec hard anodized finish resists bore wear and surface abrasion for long service life in high-heat competition environments. Can be mounted directly over studs on a 4.75" center, or used with a radial mount bracket kit. Sold individually.
