lol yea i think it was a few years ago when i was going coilovers , glad to see it hasnt changed.

got side tracked reading about their active shock management...whats a couple grand if it means i dont have to manually crawl under to make shock adjustments

Ehhh what's a quick crawl around when you already rebuild half the motor weekly.

***Edit*** Idk how much Atomic makes selling their products but I'm impressed how affordable they are compared to Wohan's finest QA1.

I was really beating the truck today on my friday errand runs and noticed that even without a front sway bar the truck feels easier/lighter to throw around in corners. Also I guess I didn't realize it but it really did terrible on the highway before the front rebuild. I used to get a lot more wandering and small patches of rough asphalt would almost give it a minor vibration that would last for a few more seconds after returning to smooth pavement. Almost like a tiny mini death wobble, kinda reminded me of Apollo 11 when they enter the atmosphere.

Anyway need to find a better mount option for the fogs still, they sit way to far back in the holes.

Here's a cool pic of the lowbeams+fogs illuminating my new driveway. I love the output from such a simple setup. I'm hoping pulling the fogs out of the hole allows their pattern to widen.

I still don't get it. There is no "preload". The weight of the vehicle is on the coil, so the coil is loaded. I guess you could call that its "preload" since there would be more loads to come as he drives. It would be loaded more (dynamically) as the suspension is compressed during driving. But, it's just loaded nonetheless. With the weight of that corner of the vehicle on the coil, it will compress a certain amount until the spring rate and the weight acting on it balance out and that's it.


Here's my angle:

If I were to hold my hand out and set a lightweight spring in it (think wastegate spring), then set a 5 lb book on top of that spring but kept my hand perfectly still, the spring would compress X amount. If I raised my hand, you're telling me that the spring would compress (assume more preload) while the book would remain at or very near the same height in relation to the ground?

I bet that if Dan cranked up on the perch as far as he could without hitting the maximum extension of the shock and measured the coil's overall height, then lowered the perch as far as he could without the shock hitting its internal bump stop or any other suspension component hitting whatever limits its movement and measured the coil's overall height, the two measurements would be the same, within a tiny fraction. There would be a little weight change acting on the spring due to the shifted weight of the vehicle.

theres no preload unless you tighten the coil past the "free" length. setting the jam nut up against the spring to where it can barely move within the shock is for the most part the free length.


your analogy doesnt work because we are always starting with the shock at fully extended length before you put any weight on it. the two mounting points can never be further apart than the shock. for your analog to work it would be like putting the jack under the control arm and lifting. youre moving the mounting points not putting preload into the spring

if you start with a 20" shock and put an 800lb/inch spring on it with no preload. 2400lbs is going to compress the spring 3 inches.

same 20" shock but you put an inch and a half of preload on the spring (1200lbs) when you put 2400lbs on it there is already 1200lbs pushing back out so only 1200lbs of it further compresses the spring. because our mounting mounts are a fixed 20"apart you've only brought them 1.5" closer together with the truck weight

dans going to have to do the science

After reading, rereading and rerereading this exchange, I have to say I agree with @randeez on this one.

dual adjustable too? nice i still need to measure and order some new ones

Can i use something like this on the 04 escalade. I really want to lower it a inch or two get rid of the air ride without loosing ride quality?

For the front this deletes the torsion bars and You need the lower mount that atomic makes, the top uses oem stud mount I guess @Dantheman1540 ?


For the rear, these are replacement shocks. The air ride helps with payload capacity, some people throw the Firestone bags in the coils to make up for it.

Best riding lowering kit available for the front IMO. You don't necessarily need the upper mount I'm using stud top directly to the OEM shock mount with Atomics custom bushing. If you look around his site he has a very detailed write up about the swap and all possible options.

Alright, re-measured and the driver side continues to drop a little down to 33.5" so I decided rather than continue to crank it since it rides amazing I dropped the passenger side to match. While doing so I decided I always wanted to do a 5lug swap and the last OEM part on the entire front end was happy to oblige

That sides lug studs have been finicky for a while and I always hand tighten before dugga dugga but I may have forgotten to do that last time since I've had them on and off 13Gazzilion times in the last week. Oh well, I'm not worried and If another one does it then I'll replace the hub otherwise it'll ride till it gets noisy.

I'm having about as much fun replacing wheel bearings on my daily
