Outer Limits 4x4 Board

Has anyone ever shaved the bottom of the rear gq patrol diff that has been fitted with 4.88 ratio gears. if so have you got pics and how much extra have you gained ?
Thanks people ! cheers lukey....

Just a question. No malace intended but is this really worth it? I can see the point on a comp rig trying to get every inch of clearence possible but for a weekend warrior like myself should I even waste my life. How much extra clearence do u get and is it possible that this may damage the diff having less capacity to hold/cool diff oil? Again I'm not being a downer I'm just curious of the actual benefits.

For an everyday truck.....

Definately not worth the hassle.

For a Truck used for heavy duty comps, then yeh every bit helps.

If you want more diff clearance for an every day truck, put 2 inch bigger tyres on it.

Screwy

thanks wicked, but i think your diff is a H260, but i have the smaller one same as a front . does it have 4.88 ratio in it anywayz ? how did you do your drain plug ? cheers lukey

On my old Comp truck i hade both front and back done, i think it was about 20-25mm additional clearance you gain, i also did the H260 and it was about the same gain.
As mentioned probably not worth it on a recreational driver as you lose your drain hole so most guys wont wont that.
For a Comp truck you would be mad not to do it.

I did the girls and it still has a drain plug.

i can't see why you wouldn't do it for a daily driver if it didn't cause an oil supply issue inside the diff. im guessing oil would need to be changed more regularly as it would not last quite as long, perhaps a sump of some description could be added to the design - have seen these on jeep diffs where the owner wanted more oil capacity but the diff kept pumping it out the breather, so made like an expansion cylinder and this allowed the oil to circulate in the diff and chamber without the need for pumps etc.

Mind you I have only formed this opinion rather recently as my Jeep on 33"s has more or less the same diff clearance as a mates Patrol on 35"s. This is due to the Jeep's little diffs. And I do have to say that it has been a good thing to have the clearance in quite a few places. Depends on your terrain I guess but if I ever moved back to a patrol it would be something I'd consider as it would reduce the requirement for big tyres (which is becoming an issue in QLD).

comes down to what want from it i guess.

Ratios don't change clearance

thanks everyone .... this is for a comp truck..... time for chopperty chop chop ! haha

Measured H233 rear axle today - really I don't undestand how won 1'' there
Me seems 10mm maybe - sounds sensless

please pick's how shave to won 1''

years ago i had a look at my H233B rear but the C/W was only about 5 or 10 mm from the bottom of the housing so i didn't bother shaving it.

superior's truck used H260 in the back im pretty sure.

don`t really know now ...... should i or shouldn`t i go chop crazy ? might have to measure up more accurate !

Can gain between 16-19mm by doing this, and make it more slide friendly.

We have been removing the lower carrier stud and welding a nut internally and using a bolt with alloy washer to become the drain plug for the oil.

Thanks AUTO CRAFT
