Lift blocks good idea?
So I found lots of results when searching for rear lift blocks but not a whole lot of information on the pros/cons. I recently did the x code swap on my excursion and got a lot more front lift than I thought. I'm currently about 2.5-3inching taller in the front than I am in the rear. I cant really afford new rear springs at the moment but also cant stand the "cali lean" I have right now. So my question is are lift blocks legit? Good brands vs bad ones? Average price I should be spending?(ive seen them from $40-$150). Its temporary until I can get the money for a proper rear lift. Thanks guys

I wouldn’t do liftblocks! Especially if you are running the factory X springs. You will have more axle wrap due to the leverage induced by the blocks. I would get the proper springs. However if it is temporary and your not towing it may be OK as long as you can deal with the increased wander you will have!

Excpect lift block some can not and do not cause wander.
If you are going to use a block taller then the factory block I’d use these along with 3/4 ubolts and torque them to spec.
Ford F-250/350 Fabricated Lift Blocks
a taller then factored block will cause more axle wrap but your stock anti-wrap bar is installed and the snubber is in good shape it should keep it under control during normal street driving, During aggressive 4 low acceleration and snow full throttle acceleration.

I have DRW C code springs and a factory F350 rear lift block in my excursion, to go with my V code front springs. All OEM factory parts.
I do not have a wandering issue.
The main thing to consider with any lift block for the rear is maintaining the correct driveshaft geometry. If you have a CV type ujoint on driveshaft than an angled block may be needed. If no CV type driveshaft than a flat block angle block should be used. It boils down to:
CV = all angle is at the CV joint, none ( < 2 degrees down)at differential.
Non CV = same angle at differential as at transmission/transfercase.

So I found these helper springs for around $100. I think I would feel more comfortable with these as long as no one has anything bad to say about them. Trying to source some F250 springs near me but most of the pick-a-part don't have any f250's.

Choose the lesser of the 2 evils
1. Lift blocks = increased axle wrap. at least your ride quality is same as stock
2. Add a leaf = increased spring rate., rides like a empty dump truck.
