Hey guys just a question i am thinking about fitting 4.6's to my shorty gq as it becomes fairly sluggish when i put the 35's on. The only thing is that the local cops in my area are starting to pay more attention to 4wd's with 33 inch plus tires. so i would like to run 31s or 32s on the road. i only do 200km a week to and from work and as im a night shift worker the roads are fairly quiet. my question is will the car be undrviable with 4.6's and 31 or 32 inch all terrains. i never really do over 80kms an hour unless im going away and then i have the 35's on anyway. So what do you guys think will the car be drivable on the smaller tires with 4.6s or will it rev way to hard. Oh just in case anyone says about doing transfer case gears. the car doesnt go to bad in low its in high that it gets sluggish and as i do quite alot of high speed dirt driving it becomes a pain when you either have to hold the car in 3rd gear and rev the crap out of it or go for 4th and then be fairly sluggish. so what do you reckon guys?????

you will be doin about 370rpm more in 5th at 100km with the 4.625 gears in it, Why not run 33's they are legal in qld on the gq. std tyre was 815mm dia most 33's are around 830mm which is leagal

I loved my rig with 4.62 from a 2.8td GU and 33". So much power and control.... went to 37" because I needed the clearance!!

so general concenses is that i should run 33's that was my first thought to. only prob is i cant afford another set of tires for 6 months. so do you guys reckon it would be drivable?? ill start saving for 33's but need to work out if i can do the ratios yet or not????????

2.8 TD's have a different gear box to a 4.2, if u run a 2.8 the 4.6 diffs will be ok but im assumin that if u want 4.6 u will 4.1's or lower, so yeh it will rev hard at 100 on anything less than 35's, but with 35's ur speedo will almost be spot on, mine is anyway i run 35 BFG muddies as my roadies

with 4.88 my speedo was perfect with 37s so 35 and 4.625 should be ok
