Product images may differ from actual product appearance.

Wilwood's Grand National III is a time proven high performance brake caliper that has been widely used with 5 on 5 hubs for stock car, road course, and off-road competition. The 3.50" mount configuration (also available in 6.00" mount) incorporates this legacy of enduring performance, with options available for the latest brake system heat management technology.

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 brake calipers available. The brake 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.
