Tranny & Rear Diff Parts


Wolf Creek Racing has developed a CV axle kit that easily bolts on in place of your standard halfshafts for 510's, 610's and Z-cars.

Wolf Creek Racing CV Axle Kits for Datsun 501 and Z-cars

We now stock Beta Motorsports Subie STi R180 Side Axles:

Differential side axles that allow the installation of a Subaru WRX STi R180 LSD differential into a Datsun S30 or 510 using the stock Ujoint halfshafts or WCR CV Axle kit. Custom machined out of 4340 billet and heat treated to a hard Rockwell and then Cryo-Treated, these shafts have the Subaru 27 spline axle and the standard Datsun halfshaft flange. Supplied without the press in bolts and sold in pairs. Here's the original production thread on

**********************   THIS IS BY NO MEANS A PERFECT/COMPREHENSIVE LIST   **********************

Use at your own risk, but this is the best we have been able to attain over the years and we feel it is correct.

Like all R180 diffs from late 70's to today, they are 115mm ID Ring Gear and will have a large "K" cast in

the top of the case, just like Nissan diffs.  We swap the Torsen centers into Nissan cased gear pairs to obtain

what ever gear combination we need like 4.11, 4.38 and 4.63.  


This above listing is for USDM Subie STi models.  


Japan, OZ, Europe and possibly Canadian models may or may not match this info.

A few notes about our Classifieds

This is the latest, greatest update to the classifieds page.  We have many more parts available than in the past.  Most of what we are offering are  Hard-Core Racing Parts.  We only sell parts that are in good useable condition.  In many cases, we obtain these specifically for selling on this page, in other cases, these are parts we no longer use ourselves.  IN ALL CASES, we check the parts and offer them for sale as shown.  We try to represent them in their actual condition and try to offer pix wherever possible.  In almost all cases, the prices shown are almost exactly half of the original MSRP of the parts.  We feel this is extremely fair for parts in good to excellent condition.  Parts that are a little further past their prime are priced accordingly.  In all cases, I may be willing to dicker if WE feel the price will be mutually acceptable.  It doesn't hurt to ask.

This page will be updated at least monthly so e-mail if you see anything you are interested in.  We accept CREDIT CARDS, Paypal , MO and personal checks.  I ship immediately on CC, Paypal and MO's.  Personal checks take 10 days to clear.  I can ship anywhere via UPS ground.  Shipping charges are extra.  A note about Paypal ; Paypal has fees associated with the use of their service.  These fees amount to about 3% of the transaction.  You, the customer, does not pay these fees, I do as the merchant accepting the transaction, credit card or cash.  I will accept and pay the fees up to $200.  Over that amount, the 3% must be added to all purchases.  Your satisfaction is our guarantee.  If you are not happy with something, return it for refund minus 15% restocking charge & shipping charges.
