I'm thinking about removing this bottom leaf if possible. I never tow anything heavy and my truck sits a little to high in the rear as it is. Is it a removable? Will there be any negative consequences? It is a 2.5 inch super lift spring. Thanks!

The very bottom leaf is an overload spring. Yes, you can remove this. When you do though, you might as well install new center pins and U-bolts.
 
id take it out, cut it down and make it into a "Zero Rate" or buy a "Zero Rate" and put it in. That way you dont lose any height in the process

reread. he said he is to high for what he likes.

how old are the springs. if new thay will settle in a bit.

and its as the name implys overload. if you wont ever get ther you dont need it.

and yes never reuse centerpins and ubolts. not a good idea. from fist hand experence waaaaay back in the day before i found it out the hard way. almost lost a dana 60 front axle at 55mph :eek1:
 
Why would I want to install new bolts and pin? The lift was just installed in July so the hardware is pretty new.
 
centerpin is fine thread and super tight and grd 2 bolt. thay dont like to come off. and most spring makers hammer the nut over to help keep it from backin off.

and ubolts are a strech bolt / tourqe to yeld 1 time use item.

plus lift kit ubolts are cheep junk crap and use cheep nylock nuts.

like i said i tryed years ago to reuse some that were few months old. i almost lost my dana 60 front with 38" tires on the highway at 55-60 mph. NOT worth the life of me or others.

some people reuse but i will never reuse . and ditch the 9/16 dia rod ubolts most give out and ask for 5/8 rod. its gr8 spec and fits in the toip plate fine and clamps a lot tighter.


oh ya i use to work at a spring shop for a year and did lots and lots of this stuff.
 
I wouldn't remove it. I did that on a previous vehicle and it was bouncy as hell. When you drive it does help the suspension. Why dont you just get a shorter block?
 
If yours was bouncy as hell, you must have not had good shocks.
 
his 6 leaf + overload will be just fine prob with no overload. most stockers are 3-5 leaf max.

and lift springs are stiffer than stock stuff with no real arch.

nope it was all brand new shocks, maybe yours are too stiff :whistle:

It was on a stock 2dr Tahoe 2wd though. Im on other forums and was warned not to do it but removed it anyway...needless to say I installed it back in a couple days later. You can look at it and see its only 3/8" from touching the leaf pack. Maybe on 6" lifted leafs it wouldnt matter but his is only 3/8" from touching now so you know it touches it while driving.

Well everybody's rig performs differently than others. Tahoes are ass-heavy, like a Blazer. All that weight must have softened the springs up a bit.

Thats highly possible, it was heavy. However, I will never do it again, I would personally get some smaller lift blocks...jmo

Now you mentioned the blocks in the other post, that'd be the route I'd go for a quicker job.

I was replying along with the other comments because thats what I thought the original poster wanted to do.

So right now I'm gonna say "switch to shorter blocks" and call it done.
 
I would get a smaller lift block or remove the leaf above the clamp leaf. Also, you take a chance of overflexing your pack if you remove the overload.
 
I would not remove the overload spring. I did it to a pair of 4" Superlift springs and the spring pack ended up sagging big time in a short amount of time and I had to replace the springs. Believe it or not the main leaf IS supported by the overload spring and removing it WILL affect the rest of the spring pack.

Did, or does his lift come with that overload spring? If not, are you supposed to reuse it?
Is it only supported when loaded or as it sits now? Just curious Scott.
 
The lift springs come with the overload and it does support the rest of the spring pack some without having a load in the vehicle.
 
Shorter block is the best answer.

As far as removing the overload I have done it many times on quite a few different rigs, Dodges Chevys, Fords, Toyotas etc. Its a hit or miss even on the same spring pack. One thing that is true with all of them though without the overload if you overload the spring it will fail much more quickly than without.

Remove the overload at your own risk, it may be just fine or it might do as Scott suggested.

A shorter block will cost a bit of money but is by far the best solution.
