4.11,s and lockers fitted

[UKLRO]

Finished rebuilding my diffs with 4.11 ring and pinions at the weekend. Also fitted a rear Detroit locker and front Detroit Truetrac. Hopefully get out this weekend to try them off road, but on the road the 4.11,s have made a huge difference to the driveability. I am running 235/85 tyres and it really knocked the edge off my TDI during regular driving.

Good stuff Andy. Did you do the diffs yourself? Pretty specialised work that.

[UKLRO]

Yes, did them myself. Fairly straight forward, just had to wait a few days for the dealer to get some new shims for the pinion bearing. Ashcrofts are really helpful with setting the diff up.

Can I assume these were sourced from Ashcroft, and that you are in the UK?

how do you find it on road, not over-revving at highway speeds. Reason is I'll be running similar set-up but undecided as to 4.11s or not.

Hi Andy;

I'm looking to do the same on my Disco, currently in the process of ordering the tyres 235/85R/16's, from your post it seems Ashcroft did the actual setting up of the diffs etc and you installed them on the vehicle?

[UKLRO]

The ring and pinions were manufactured by Ashcrofts in the UK, I bought them from Opposite Lock in Midland, Jezzaol on here. I had to fit them along with the detroit Lockers, also from Jeremy.
It drives fine, definitely notice the difference with the front pulling a little, but nothing wild. As for the tyres, if you are going with 235/85, I would definitely reccommend the 4.11,s. It drops the gearing back to where it is with stock tyres. Without the 4.44,s the gearing was too high, made it a pig to drive as the motor was always working harder to pull the big tyres.
My opinion anyway!
