Db rods coilovers

[Chad006]

Hey guys, just spoke with Jon at db about doing a set of his coilovers and i was just wondering what you guys who are running them thought of them? I am in the process of tracking down parts to return my truck back to stock ride height but it's proving to be a pain. Jon recommended 1100-1200lb springs, that sound right? Trucks a DD and weekend warrior just got tired of rough ride and want something different.

I suggest you do a search of "coilovers" and get to reading, esp this thread: http://www.duramaxdiesels.com/forum/showthread.php?t=43383&highlight=coilovers
Member 408.Luke had his done at DB's....I think his truck may have been their first set.

I've got them on both of my trucks, I love them.

Ya I have read that thread and a few others on coilovers for it, just wasn't much info on the results of them and how guys were liking them.

What parts are you looking for to go back to stock..., I might know a guy who has that kind of scrap pile about 10'x6'x4':roflmao:

I have em and Love em .

So I spoke with Jon again after taking some measurements and came up with 14.5" with the shocks supporting he load of the truck. Does this sound right to you guys? That was with flat cv angles on a stock height Lbz which is what I would like to maintain.

Unless he changed the shocks from when they were posted on here, they are too short for a stock height truck. And a 100% stock truck will measure 14.75" from the bottom of the frame mount for the shock to the center of the bolt hole for the shock on the LCA

Ya Jon had mentioned using different spacers I believe for the stud end of the shock but I could be wrong? He was gonna contact ridetech and get back to me first of next week and let me know the verdict. Do the 1200lb springs sound right for a daily driver, I've read about allot of guys running 800-900? I'm assuming it is valving in the shocks that dictate your spring rate?

I had a spring engineer run the calculations when I had a custom set made for my fox shocks, at 6000lbs with approx. 2000lbs on each front tire he suggested a 1050lb 12"x2.5 spring. I can't comment on how they feel yet because my truck has been dormant since purchasing them.

Yep, James told me I need to know corner weights, total weight, ride height and suspension travel distance to know which length shocks and which springs will be best.

You will need about 2-3" of spacers, not something I'd recommend. You want 1-2" of preload in the spring to get desired ride height. There are other factors to consider as well that I'm not going to go indebth on as I've posted this info many times before. Spring rate is determined on many factors and heavier isn't always better

The spring needs to work with the shock. Coil bind is a real threat on these trucks so calculations need to be ran so that the given ride height can be achieved without running into coil bind. At that heavy of a spring, you have a very limited amount of preload available to get your ride height.

The spring will see double the load of the actual corner weight

I ran them on my white truck for awhile but they lowered the truck wayyy too much IMO.

 

[Chad006]

Ya that would be no good for me at all, I need to maintain stock ride height. Starting to lean away from jons setup now as I don't believe it's the best option for what I want. Hopefully can come up with a solution for the stock ride coilover setup.
