I got a ? for you guys I do know blocks suck on a jeep but I have blocks on my dakota and they haven't hurt the springs yet.On the xj I 'm thinking its just cause the springs suck that they are just a low qaulity spring pack.( blocks have been on the p/u for 5-6 years)

 

Whats the question? Are blocks o.k. to use? Yes as long as you don't wheel hard or at least use a anti-wrap bar. Spring wrap is what you need to worry about.

 

not to sure what your ??? was but blocks aren't all bad just when matched with junk springs for lift
it'll work but ride like hell i would guess

 

That will put a lot of strain on the U-bolts when wheelin. Plus they can break your springs.

Wheelin with blocks is just not a god idea.

 

do you mean it'll break stockers or a new set of lift springs?
stock i could see breaking but not a set of re leafs

 

I can see it breaking any set of springs over time. Especially if you have a load on them.

If you are going just for looks then great use blocks. Your ride will be rougher but it will just look good.

I would not use Blocks when Wheelin.

DO IT RIGHT!

 

I'll refraze the ?, Why do blocks ruin springs on an xj and not on a p/u truck they come from the factory on most p/u s and dont ruin the springs.

 

How come they come on a lift kit for a p/u kit includes springs and blocks u bolts etc, and I can wheel that with no problem not begin a dick just want to know whats the differance. Also I would never wheel a xj with blocks.

 

use them, you be the judge. everyone has their own opinion on blocks. fact is they cause axle wrap.

 

If you take and look at them they are really just a tall spring perch, you and I know the differance but a leaf spring doesn't ,I dont know hell I cant figure out why they suck on an xj and have no negitive effect on a pickup, but I wouldn't use em on an xj.

 

I think the problem is because the leafs on an XJ are a lot thinner than any truck.

 

I would not have the on a truck either. I don't feel like writing everything I read from just googling (pros Vs Cons lift blocks) So will let you google it then read it yourself.

Plain and simple Lift Blocks are a poor mans lift on any vehicle. If you have the money buy Leaf Springs.

 

This is from a Toyota Tundra forum which is a Truck (for those that think it is ok on Trucks) They basically state the same thing we say. Don't use them offroad.

Lift Blocks
In the off-road community, the lift block is also known as the devil. Not many people like them due to the side affects of having them. One, they are prone to breaking, and two they increase axle wrap tremendously. The upside to that is they are an inexpensive way to lift the rear by as much as 6 inches. Basically the block lifts the rear by being placed between the rear axle and leaf pack. The leaf then sits on the top of the block, thus providing lift. Companies that make drop down bracket lifts (Trailmaster, ProComp, Fabtech) use rear blocks in their lift kits. As stated blocks are inexpensive, but they do have problems. It is recommended that you avoid large blocks if at all. Most companies use aluminum for their blocks which is prone to breaking. Cornfed (www.cornfedsuspension.com) uses steel for their blocks, which is much stronger.

 

lol, that reminds me of a guy in my old neighborhood who had an old Dodge truck on blocks... like 3 hollow blocks stacked on top of each other, plus one or two solid blocks under all that. It was insane. I wanted to get a picture before we moved but he was always out there when I was thinking about it. I'm going back in a few weeks to check on our house (that hasn't sold yet), so I'll try to sneak a pic then if the truck is there.

 

what about shackles? sorry i cant spell. i had bigger shackles on my 99 xj and it ruined my springs, is that commen?
