STROKER KITS

BC high performance stroker kits take the guess work out of building up your bottom end, featuring system matched parts that are designed to work together seamlessly the first time. All BC crankshafts and connecting rods are machined on the latest CNC equipment to guarantee accuracy, reliability and overall consistency using the highest quality 4340 steel available. When you purchase a BC crankshaft and connecting rod combo, you can be assured it was made with the finest steel alloy, employing only the best machining, heat treating and finishing procedures, in stock at a very affordable price. Pistons for the stroker kit are your choice of JE or CP brand, made to any desired bore size and compression ratio. Added features available are upgraded, 9310 alloy steel wrist pins and ceramic crown top coating and/or moly dry film skirt coating. ACL Race Series bearings also available separately.
