37" maxxis on a GU

[joe crothers]

My brother has a GU with a standard 4.2 diesel (no turbo), he has just
had his diff ratios changed to 4.625's. He has been thinking of running
37" Maxxis Creepy Crawlies. My question is, with the 4.625 ratios and no
turbo, will his standard diesel turn into a slug on and off road? Or will
it handle them no worries.

MAte i have a competition GU ute non-turbo and i run 37" creepys and i still have the normal diff gearing and handles fine but i do not use them on the road at all only samll trips and seems fine except up hills, overall no dramas

Mate the 4.2s like a bit of load and with the diff change and the bigger tyers dont be suprised if you feel it goes better with the bigger rubber.
I had one in a GQ non turbo and when i put the boat on (16ft tinni) it pulled alot better but dont get to greedy as to much and you will kill it.

by normal diff gears he means 4.1's and with ya foot to the floor down hill its flat out making 130, 4.6's will help a fair bit if yourve got them. Bu ti do agree not to run the creepys on the road, they will chew up badly.
