If you're on this page, you have probably heard of the infamous RB oil pump gear failure.  You're probably looking to upgrade your crank collar to one of these.  The early R32 (anything before series 2) crankshafts are abundant, and they're all the previous design that led to many RB engine failures.  The flats machined on to the crank are wider on this upgraded collar and allow for a complete and proper engagement of the oil pump drive gear.

This RB Crank Collar is made from Forged EN26 Steel.  It is much stronger than the crankshaft itself, as well as resistant to wear.

Protect your RB26 from oil pump failure and order one of these. 

Are you worried about it being installed properly?  We've done MANY, it's really not that hard, as long as you follow the correct procedure for installation.

Instructions for installation available and can be mailed directly to you or your machinist.
