High Tensile Diff Bolt - Bf

If you can get your hands on a hard copy of the superpro catelogue the bolt type is in there... its not on the online one.

or ring around some decent suspension workshops someone will know...

I just a bought a grade 12.9 (I think standard was 8.8 or 10.9) unbrako cap screw from blackwoods it hasnt broke yet I have had it in nearly 6 months now. Im pretty sure it is an M16 x 120mm. I have pics from when I did mine. Although mine has held up, I dont know if a higher tensile bolt is actually the answer, a higher tensile bit is actually more brittle which is more prone to shearing as my original did. By the way I only paid $4 for the bolt as it is only a bolt, dont get ripped off by someone telling you its specially designed for an xr6 turbo diff.

I think the biggest improvement with the unbrako is it has a longer shank which goes into the diff so at least the strongest part of the bolt is placed in shear, unlike the stock POS...
