GU Rock Crawler Gears

[pjhicks3]

Just after some feedback on anyone who has fitted Marks 4wd Crawler gears to their patrol.
I have a 2008 GU CRDI auto, with 33" tyres, and the low range gearing is rubbish.. Looking at some options either - 43% reduction gears, or 85% Reduction gears. Wanting info from anyone who has done this, and if they were happy with the results.

Thanks.

unless you are into serious crawling go the 43's. 85s are slow and you also need to grind out the T-case housing and selector fork so they will fit

Thanks Heaps for the Info, I think I am going to go for the 43's and maybe some diff ratio's to combat the large tyres..
