POWERTRAX and LOCKRIGHT locker units are readily available at reasonable prices.

The powertrax no-slip traction system is for off road on road 4WD's or rally / tagar race cars, a little more smooth and less harsh with more spring retention and angled locking dog teeth.

The LOCKRIGHT is for the more severe 4WD / race car that is abused at all times.

Both very good units are respected all over the world.


We do a huge range of new and used parts. For these products, the worlds most used and abused Differentials.

The ford 8" / 9" Diffs are all about 20-40 yrs old now so are in need of that much awaited rebuild. So we stock all new parts from standard ford to street race, lightened to full alloy DISC' to DISC Drag race or road high performance units.

Also we provide axles, LSD lockers spools/ mini, housing crwlpin etc.

The Ford 8" 4spider LSD unit:

The ford 8" only came out with a 2 spider limited slip unit that was adequate for standard use but with today's technology the horspe / tourqe power curves have gone up so the units aren't so appropriate anymore. So through some Research and Development we have come with a new unit. The 4spider track lock that has the same strength as going to the Ford 9", as this saves weight and room. It is a great way to beef up your Ford 8" rear end. These units can be set from 80-250 ft pbls of break away fourque depending on the application needed (28/31 spl).

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.
