solve two problems found in traditional heavy brake systems: excess unsprung weight and inconsistent braking performance under off-road loads.\u003c\/p\u003e\n\u003cp\u003eThe forged Wilwood calipers significantly reduce flex under pressure, giving a firmer pedal feel and stronger clamping force. Paired with 13.5\" rotors, the system increases braking torque by running more rotor surface area through the pads at any given wheel speed—meaning more friction with less pedal effort.\u003c\/p\u003e\n\u003cp\u003eThe reduced unsprung weight also has a direct effect on suspension performance. Lighter components allow your shocks to control the wheel more effectively, improving traction, reducing chatter, and keeping the vehicle more stable on rough terrain. When combined with Crane’s precision-machined rotor hats and bolt-on brackets, the end result is a brake system that performs better, installs easier, and holds up to long-term abuse.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"Crane Axle","offers":[{"title":"Default Title","offer_id":56095459344550,"sku":"CA01039N","price":1335.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/CA01039N-Crane-Front-UB-Wilwood-Brake-Kit-1.jpg?v=1777651516","url":"https:\/\/wideopendesign.com\/products\/crane-axle-front-unit-bearing-wilwood-lightweight-brake-kit","provider":"Wide Open Design","version":"1.0","type":"link"}
