This girdle kit uses a 1/4” 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.


Girdle plates require machine work and precise measurements for correct installation, this should be performed by a ceritifed engine technician. The IE Tall Boy main caps will need to be line honed by an engine machine shop with the supplied IE Spec ARP studs installed and the nuts torqued to ensure journal circularity. Tall Boy main caps will also need to be measured, and machined flat between the girdle plate and engine block surface. The tolerance for the gap between the girdle plate and block is 0.001”
