Under high RPM and power use your block can begin to flex, causing severe main bearing wear or even a broken crank. Reinforcing the block is a necessity for these extreme applications. This girdle kit uses a 3/8” steel plate to bolt on the underside of your block to reinforce it and prevent from flexing under high power use. The girdle plate bolts to all of the main journals, using the supplied extended-length ARP main stud kit. It is then sandwiched between the block and the oil pan to keep the block from flexing. This kit includes all lengthened hardware needed to install the girdle plate using IE “Tall Boy” billet main caps.

Zinc plated girdle plate
