Our VG30DETT Billet Main Caps and Girdles are machined from 4140 Chromoly Steel.
Engine will need to be line bored/honed and also machining for the thrust washer once these are installed. We can provide these services if needed.
Comes with ARP Bolts to attach girdles to main caps.
This is our 4 bolt version. Extra machining to the block will be necessary to fit these caps. Only the center 2 caps are 4 bolt. The bolts holding the girdle will go through the caps and thread into the block.
