Main Force Performance

MFP (Main Force Performance) has developed a proven problem solving solution with their Supercharger Crank Support Kits. The factory crank support system on the 5.0L Mustang and Shelby GT500 are the weak link when installing an aftermarket supercharger. The added force on the belt & pulley system has been known to flex or snap the crankshafts causing catastrophic damage. The MFP Crank Support kit minimizes any flex or movement in the front of the crank to help prevent breakage. Designed to greatly increase the strength and keep the crank in place and in one piece. Beefcake Racing is an Authorized Dealer, call 1-855-827-7223 from 9am-10pm EST.
