I had been looking for lockers for ages, got mine from Newcastle, then you advertised yours, and a couple more have changed hands since.

I think I will revert the CWP to 3.55 for now, and if I decide to get the engineering done etc for larger than 31" tyres, then I can go back to the 4.11s. Probably should check the $ to change the Transfer case to 1.2 instead and at the same time could add Maxi lower low kit.

Decisions decisions!

7.50 x 16 tyres are 408.5 revs. per kilometre & 31 x 10.5 x 15 are 417.4 revs. per k.
