IE Crankshaft Girdle Kit for BMW M50/M52/S50/S52 Engines

$699.99

Item #: IEBEBA3


Overview

Due to the length of the crankshaft in an inline 6 engine, extreme harmonic vibrations can happen under high RPM and power use. This causes the block 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 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. Spacers are included for use with factory main caps, but IE “Tall Boy” billet main caps are a highly recommended for high power builds.

Kit Includes:

Zinc plated girdle plate
Custom ARP main stud kit
Extended hardware for oil pan
Extended hardware for windage tray
Spacers for girdle plate
