IE 06A 1.8T Crankshaft Girdle Kit




Making over 600HP? Protect your 1.8T 06A block from flexing, cracking, or failure under extreme RPM or high horsepower applications. The IE girdle kit will help protect your race engine from severe main bearing wear or even a broken crank.

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 OE main caps and girdle spacers.


  • 1/4" steel girdle plate for ultimate stability
  • Reinforces engine block and main caps
  • Protects mains, bearings, crank, and block from flexing
  • For use with extreme HP and high RPM
  • Manufactured and engineered in the USA

  • Installation instructions

Girdle plates require machine work and precise measurements for correct installation, this should be performed by a certified engine technician. The 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. The girdle spacers will 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”
