Small lift
 

What is a 3in or less lift for a 83 yota 4x4 I have read up on the 62in swap and ruf but I do know want to have to do the modifications to get those to fit. I am only running 33 with no lift as of now and have no scrubbing problem but it does not flex very well and the front leafs are sagging to the point there backwards.

Your kind of at a sticky point.

A simple body lift like 4crawler sales will give you height but no added suspension benefits.

Stock length lift springs will also give you lift but lift springs, more arch with out longer length will not give you anymore flex plus a rougher ride.

But an option would be to look at stock height springs with a small body lift. But you will need to stay with stock steering so height steer will not be an option. Alcan may be worth looking into, I've read good things about them.

Do some research, each modification has pros and cons. Gives you chance to plan direction of your rig in future.
