The use of this product requires some machining. The surface where the rod bolts nut clamps against needs to be machined so the distance between
this surface and the one that the rod bolts head clamps against is approximately 43.5 mm. ( the measurement is about 46 mm before machining)
This to get full strenght with this bolt that is a little bit shorter.

NOTE! Important that this work is done correctly. Should be performed by a engine machine shop.
