I'm just thinking out loud here, so shut me down if I'm completely wrong.

I level my truck using the torsion keys. This obviously raised the lower bump stop further away from the lower control arm, to the point that there is about a half inch gap. And therefore my ride became stiffer.

For those who aren't aware the factory bump stop actually acts as a "damper" and under factory conditions it will continually make contact with the lower arm.

So here is my thought,

Can I buy longer, more progressive bump stops somewhere, that could contact my lower control arm at the current leveled height? Thus restoring the cushioning affect that is produced at stock height. I'd ideally just need a bump stop that's half inch taller.

Is this reasonable thinking?

Having bump stops in contact would stiffen the ride at this point. Part of your problem is that there is much less downward travel on the suspension the way you are set up. The torsion keys basically enabled you to increase spring rate while raising the front of your truck. The bump stops help the torsion bars at the stock setting because they are 'looser'. Basically bump stops only make the suspension more stiff and in effect increases their spring rate as the suspension travels downward.

What you could be feeling is the a arm hitting the bump stops with more momentum and force as they travel through that gap you have created. In that instance its possible they would help... but I'm not sure.

Thinking about it more, and considering what you said, I guess it is unreasonable to think that bump stops would make a difference at this point. Because the stiffness is caused by the actual torsion bars being "tighter" now and not the lack of bump stop contact.

With my coilover swap I cut off the bumpstop pocket and drilled a hole through the LCA and mounted a universal bump stop there. They make many different sizes so you can buy a longer one and trim it as you like. It may help, but coilovers would definitely help your ride

I've been dying to buy your mounts, the cost of the coilovers just kills me. All said in done I think I figured it would end up costing about 700 bucks

Yea, thats about what it costs. Worth it if you ask me, but I am probably biased lol

haha probably, but it is on my to-do list. Cam comes first

The thought of some bilstein coil overs sounds so nice too..

I have longer stiffer bump stops and it did work for me. I am thinking about trying out Atomics brackets, though. That is as soon as I get my motor back together.

You have a part number or a link??

If you want an exact link I can PM you (non-sponsor link policy?)

But basically if you look up Timbren Suspension Enhancement System -- it will show the dealers you can order from. The fronts made a big difference in the ride. The rears didn't give me as much improvement.

They were 200 bucks but I went for it anyways because on the Yukon you don't have many options for torsion bars and I wanted to make the front ride stiffer.
