no offense but that's gotta be the funniest dumb comment I've ever heard!! The top of a good block has the same if not more surface area of a stock perch! Putting blocks on doesn't make the spring negetively arch any more! The only reason possible that a spring will break with blocks is cause your stacking blocks, using small dia. U-bolts, using too tall of blocks. Which all of those will cause axle wrap and will break your spring 99% of the time in front of the axle. Not the blocks fault, but the owner for not securing the axle better.

 

I understand the shackles vs leafs,

But when you go to rustys website, go to the XJ Cherokee 4.5" Spring Pack Kit and go to the choose leaf option, you can choose the 4.5" spring pack OR the 3" springs + 1.5" shackles for an extra $40. For a total of $709.00

Now if you go to the XJ Cherokee 4.5" Add-A-Leaf Kit it already comes with the springs and shackles for the rear and the same everything else for a total of $589.00

So whats the point of it giving you the option in the Spring Pack Kit for the Spring/Shackles for the rear and you getting charged $709 when you can get the same in the AAL Kit for $589?

Just a little confused on that part if you kept up with my explanation lol

 

exactly the point i was just gonna make DP
and with a 3 inch pack the spring is flater thus more flex thats another reason to use blocks and shackles and i dont wheel with to many full size all mid size

 

main reason blocks are a no-no is because they promote axle wrap, which in itself can cause cracked leafs

 

if you get oversized blocks maybe but i have never seen it on jeeps with 2 inch blocks

 

Alright enough with the block debating

Back to my questions lol

 

with the add a leaf its one spring that you split your pack and add it to your pack with the other one it comes with a whole new pack advantage new leaf spring

 

first off BLOCKS ARE BAD over 2in they cause a massive amount of spring wrap in any rig bad for springs and u-joints....second my AAL sagged horribly after one wheeling trip ended up adding a set of 96 f-150 shakles about 1.5 inch longer or 3/4 in of lift to get it back up been fine since, but i would highly recommend full spring kits

 

sorry didn't see N2O's post....so yeah what he said (that happens alot)

 

i guess blocks are take your chance upgrade but ive never seen it in person but i have seen the theory and videos on it. i would recomend the full spring as well even tho i have an AAL it has not sagged but doesnt mean it wont plus you get new spring longer life

 

Umm no!! I had 3" blocks with 5/8" u bolts absolutly no axle wrap at alll!! It's a matter of compensating for the blocks!

 

axle wrap is pretty common, the most obvious sign of it is the jeep bouncing around pretty violently while trying to go over the obstacle.

it makes the suspension less predictable, which could end up being a safty issue if it happens in the wrong situation

 

Alright so full springs it is. Thanks guys

 

ok 3" still not overkill , there are guys with 6-7" of block out there, spring wrap has little to do with u-bolts spring wrap is caused by the added leverage the axle has on the springs and on our soft passenger suv springs they will flex under the load ..a shorter , high arched , or higher spring rate sping will have less of a tendency to wrap...
