Aluminum Lift Blocks
Well I have a question about using aluminum lift blocks for the rear of my truck. This will most likely be a temporary deal but I would like to know if you guys think these blocks will be strong enough and durable enough to withstand offroad abuse. The kit includes a couple u bolts that are 2 1/2 inch wide and 5 inch long, are these the right side to fit our axles?

Another question is if I go ahead and purchase the 3 inch block kit will I beable to level out the front of the truck with ball joint spacers and mild torsion bar crank?
Thanks in advance.

id get 2" blocks max and get steel ones so you can tack em to your perches so you wont lose em...also yor not going to want to crank your tbars another 1.5" or you wont gain any travel as you wont be able to compress the front any more then now. I'd go bj spacers, half inch crank then 2" blcoks

Hey thanks alot, I just don't know where I can get 2 inch steel blocks locally or anywhere for that matter. Is it necessary to get steel blocks so I can tack them to the spring perch, what are the chances the aluminum blocks would fall out if they are bolted down with the ubolts?

It's not that they fall out, it's that they break. Aluminum is much more likely to crack in that application than steel. You don't need to weld them to the perches, but it is a good way to keep them in place. If you don't weld them in, get in the habit of checking your ubolts on a regular basis.

Yes those look like extruded or cast aluminum blocks, and they do tend to fatigue and crack. I make blocks out of solid billet T6061 aliminum:
And in solid steel, I can do 1/2" and 1" increments.

Or you could run a length of heavy 2x2 square tubing (like 0.250 wall) for a block.
You'll need 3" ID u-bolts and probably around 8"-10" long to fit the Toyota axle and the spring pack and block. Figure about $60 or so for a set of good u-bolts. And if you have the extra wide spring perch on your '94, then it may be hard to find longer square bolts, probably need to have them custom bent. Or consider doing a u-bolt flip kit so you can run the more common round bottom u-bolt.

Ok I will have to look into the different block choices, just another quick question about shims with the blocks. When do I need them? When should I worry about ujoint angles?

I'm looking for 35 one inch square block shims. I need them for a template. I've gotta make bars for a window.
I've already looked at depot and menards. Haven't gone to harbor freight yet.
Any ideas?
