Been a long time coming that the VG30 crowd has been in need of a better setup for housing the crankshaft.  The stock girdle is riddled with flexing issues and being made in a single piece design makes it a machinists nightmare to do a line hone job on the main saddle (housing bore).  The need of keeping the crankshaft fixed can be challenging but now its going to be made quite easy with our new billet main cap system.  Made of billet 4340 these are precision cnc machined and come pre-bored to within .005″ off center so the end user has less work in having the main housing bores sized accordingly.  You will still be able to retain the standard ARP 8740 main studs or you can opt to purchase L19s (not required or suggested) but if you want to go that route you’re more than able to since this main cap system you are able to hone/size each cap independently from another.  Main caps will be black zinc coated to prevent corrosion and come ready to be final machined.

In addition a new billet girdle has also been designed to lock in all the caps together to give the lower housing even more rigidity.  Made of the same 4340 material you’ll be reassured that the quality and attention to detail are second to none and offer the best solution for the lower end of your VG30.  This kit works for both VG30E models as well as the VG30DE (TT) models.  An upgrade to the caps that will be available is an exterior oil shed coating which aids in keeping oil drained back down to the sump of the oil pan.

No pricing or ETA yet but check back for details soon.  Hoping to debut the final production part beginning of the new year.
