lift blocks

murgg · 11-26-2005, 01:21 PM

im goin SOA and was thinking about a .5-1" lift block. has anyone done this, experiences. i know the longer the blocks the more axle wrap but im planning a a trac bar anyways and its only 1 inch. i've also ready not to put lift block in the front, why not? i figured it be alright at only 1 inch and i was goni to make my own with two prongs to go into the perch.any thoughts?

Why not just get leafs that are .5-1" taller? Even with a traction bar (not track bar) you may still experiance some axle wrap. Lift blocks are a no-no in the front.

cost is why im not getting new leaves.i know there a no-no in the front but i want to no why?

just get .5" - 1" lift shackles

yea, lift blocks are stupid

get a 1/2" shackle lift and 1" body lift, youll be better off, or just trim your fenders

depends on how its executed. i turned the bottom (shortest) leaf upsidown so it had less effect on springrate and allowed more uptravel. this in effect is a 3/8" lift block. the difference is it is bolted together with the spring pack. if you were to use a 1" thick "leaf" bolted directly to the springpack with the center bolt and then obviously ubolted to the axle it would probably be fine. id use a slightly larger allen bolt then the factory one. this would require drilling out each hole in the leaf pack wich is very difficult.

"body lift" is a missnomer and really has no business even being on a offroad vehicle.

a better option is to just collect leaves and experiment with different combinations to find one that works well.

thanks for all the replys.i already have 1"shackles so thats out. i was toyign with the idea of a 1" body lift, maybe in the future.

The problem with lift blocks is that they add unecessary stress to the U-bolts. Overtime, the U-bolts can stretch and leave room for the blocks to move. The blocks can crack or even fall out.

Bastard packs ftw

In general, I don't recommend lift blocks on a YJ - but there are exceptions.

When I did my SOA, I installed a prototype MORE steering correction kit that Chris Overacker designed. IIRC, mine is either the second or third one ever made.

This kit came with a set of mini riser blocks which amount to nothing more than short spacer blocks that go between the perches and the bottom leaf, just like a standard type riser block does.

These mini riser blocks are used to help "center" the leaf springs between the drag link & tie rod of the MORE crossover steering kit - which is a good thing if your front leafs flex a lot.

Having the leafs centered, helps so that when they flex in either direction, they have less chance of contacting the steering links, especially while flexing & turning due to the inherant design of crossover steering & the MORE passenger side knuckle bracket.

So, in this case I HIGHLY recommend using a short (mine are ~7/16") mini riser block.

Notice in the first pic where the mini riser is & how short it is. No harm whatsoever.

In the second & third pics, you can see that my leaf is perfectly centered between the links (as it should be if set-up correctly).

haha .5" lift blocks wouldn't be so bad. especially if you aren't on the loud pedal a whole lot. even 1" i can't see hurting too much. 3 or more and yer into problems though.

you could use the zero rate AAL from ORD. a 1" lift blocks integrated to the spring pack

Add a Leafs, Zero Rate for 4x4 Suspensions from Offroad Design

Joe,
you used a short spacer to correct a potential problem. The OP is wanting to add a block for height.

I STRONGLY disagree with using a lift block (defined as something over .5 inch in height) in a front suspension.

In fact, most states have laws against front blocks of any type.

In a rear a block can be an acceptable way to add height. No more then an inch or so. Just understand that axle wrap WILL be increased.

**fratis** · 10-31-2010, 01:55 PM

im gonna go out on a limb here and assume the op has made a decision by now.

Yea, probably ~5 years ago.
