Rear 4 Piston Ultra Big Brake Kit

Factory brake systems are often insufficient for the extreme temperatures generated during motorsports, leading to brake fade. This big brake kit provides a solution by significantly improving braking response and overall performance, while also offering benefits such as reduced unsprung weight, longer service intervals, and simpler maintenance. The kit features forged billet aluminum split design calipers with an anti-rust coating and vented aluminum pistons for superior heat transfer resistance. The two-piece rotors are available in drilled, slotted, or drilled & slotted styles and are paired with lightweight aluminum center bells for the front, and rigid steel center bells integrated with inner drums for the rear. CNC machined steel caliper mounting brackets ensure a direct bolt-on installation requiring only common hand tools. This specific kit is compatible with 2011-2019 Ford Explorer (U502) models with a 5x114.3 lug pattern. It is important to note that this kit *does not fit* Explorer Sport models. The part number YS02R-FD-03G-022(X)(★) indicates that the OEM handbrake functionality can be retained, but only with the separate purchase of the "YSR Handbrake Adapter System." Other part numbers with (X) will not retain the OEM handbrake, while those with (V) will.
