Really depends on the the tank mate, different shapes etc. Also not all 4" lifts will have the same travel so that'll make a difference too.

Just see how you go, if it hits it's just a matter of buying a single bent arm and bolting it straight in, two bolts easy as.

 

Thanks for the quick reply,
sorry I didn't explain my self properly.
what I meant is if I do buy the bent arm, is it still gonna hit or the only way to find out
is actually buy one and fit everything up and see how it goes?

 

Yeah pretty much.

Just leave it for now, and if you did it hits buy a bent arm.

 

ill keep you posted.
should be installing them in couple of weeks.
thanks for your time

 

Like Jamie said, it really depends on the tank.
I have the straight upper arms but the long range sub tank (85L sub tank made in WA by Outback Accessories).
it has a cut-out section in the rear to give the arm room for full drop on more than 4" lift.

The bent arms will give you heaps more room for most long range sub tanks. It is really only the rear part of the sub tank as they make them to extend out under the arm and close to the diff to get maximum volume.

So before you buy the sub tank, ask if it has the cut out for clearance.

 

I have a 70lt SS water tank made by them.
The rear section was already stepped down from manufacture but with 12.5" travel rear shocks there was no way the upper arm was going to clear it so I notched it out and tigged it back up. Clears by 10mm now at full flex or droop.
Only lost about 3lts capacity

 

hi gordie
ill check the tank if its got a cut out or if it will miss the arm.
you would think that they would make them all the same so you don't have to change parts around to make one thing fit(how they got the cut out on your tank)!
what difference is it gonna make if you lose or gain extra 5-10 litres.
but every manufacture got different ideas.

 

hi
I just installed the sub tank and geordie4x4 your right about the cut out.
even with the 4 lift I stall have about 30-40mm gap.
thanks ppl for your input :bigthumb:
