going to be putting a 2" leveling kit on my truck. i see many posts here saying it is a good idea to go with longer shocks- but i never see any shock part numbers for the longer shocks!! i am already running bilstein 5100 shocks on my truck (two years old) bilstein part number be5-6681-h5-fronts and be5-6647-h1-rear. are these the bilstein shocks the guys are running with the leveling kits? or is their another bilstein shock/part number. thanks.

 

Check with Sean at Lorenz Industries - number is on the website. I believe you might be OK with the ones you have.

 

thanks festus-just checked the site-saw the 5100 bilsteins, but no part numbers.

 

Just give Sean a call. He's a wealth of information and knows our trucks inside and out when it comes to suspension and steering stuff. It is certainly easier than sifting through the site for information. After the conversation I had with him awhile back, I have no reservations he'll supply the info you need.

 

Those are the right shocks for your level kit.http://www.genosgarage.com/prodinfo....STEIN-BE5-6681

 

thanks bearhunter. interesting, though. on bilsteins site, it says this shock, which i already have works with a 2" lift on the 1500 trucks and on the 2500 trucks-but mentions nothing of lift.kind of opposite of what geno's says. but that is neither here no there- i have the right shock already!

 

Makes it easy.. great shocks also...

 

Don't waste your time with a leveling spacer, your ride will suffer. I have one and in time I will replace it with Lorenze, Carli, or Kore.

 

I would be interested in hearing how a coil spring spacer adversely affects the ride of the stock coil spring.

 

Im not sure why but it does, I think it has to do with the sway bar since the spacer is just a spacer, I have one and I even replaced the shocks, it helped some but still rides much worse especially expansion joints.

FAQ:
Why should I upgrade to new front coils, instead of throwing a pair of 2” spacers on my truck and reusing the OEM springs?

1) The OEM springs have a very light spring rate. I think this was done by Chrysler to over compensate for the very stiff rear end.

2) The OEM springs were not designed to compress as far as the 2" spacers will make them. You’re asking an OEM coil to take an extra 2" of compression. Over time you will ruin the coil, by over compressing it.

Our coils were designed around the new 2” ride height. LORENZ coils won't take a set from over compression. In comparison, our coils are made with thicker spring steel. Along with using more material our coils are wound tighter, and heat treated. The OEM Coils use thinner material, and less of it.

 

Great info!

I never would have guessed that.....thank you.

 

I call BS on this one, or are we talking about 1,000,000+ miles or maybe on baja trucks? I've had too many trucks w/ these "coil spring killers" aka spacers w/ NO problems along w/ lots of friends w/ the same setups. Never a bad spring because of a spacer.

 

i would have to agree and call bs as well. how often does you stock coil spring actually compress all the way? for the average joe, probably never. if you're out driving it like you stole it, probably shouldn't be doing it with the stock springs anyway. LORENZ- i think you're not making a fair comparison. a spacer will not compress your spring any more for average driving. i think if you are going to make a comment like that you should explain it better. especially being in the suspension business. now i do agree that "if" you compress it enough and enough times (which is very rare for the average person to do) then yes it will cause fatigue to the spring which will give you less spring rate and a lower ride height.

 

had 2" pro comp spacers on my '02 with factory springs and drove it hard for over 100,000 miles and never had a spring issue. that said, i couldn't get the factory springs out of my '05 fast enough- they felt like they were made of sponge. i could see spring failure a lot quicker and easier on the newer coil springs that dodge is using as they compress much easier, than the old, stiffer springs that were used on older ctd's. i think you could call bs if we were talking about older ctd's, but with the softer springs dodge is now using, i think lorenz is right on. jmo...
