Diff straightening:

You need to ensure that your diff housing is running true through the center and after years of abuse or welding on the housing for modifications the housing can bow at each end, which will run your rear wheels on strange angles and wear your tyres out on the wrong places and put extra load on your wheel bearings. We have a jig setup to repair this problem and other methods of setting up your rear Diff housing back true.

Ratio changes:

After modification of your vehicle whether it be engine, auto to manual, tyre size change or whatever you do your ratio may alter and not suit your needs. So we can offer you some options, for more get up and go on take off or for pulling loads on a little less boggie and some longer legs on the open road. It's just a matter of getting another ratio crown and pin and fitting it to your vehicle and this will alter your speed / rev's to your required rate.
