DJM 3" Lower Control Arms

[Wild83C10]

Soon I will be lowering my truck more then it currently is. I purchased a set of DJM lower control arms and I am thinking they may sit very close to the ground. I currently have 2" lowering spindles and I cut my springs about an inch. Any one have them installed? Any issues with ground clearance? Any pictures? Thanks

Are you going to be using the spindles AND the LCA's together? I woudn't recommend that.

I was planning on it. What problems would I run into? I am looking for about a 5 inch drop in the front. What would be the best combo for that?

I did the same thing and the A arms drag the ground. You would have to run 20's on the front to keep it from dragging.

So dwcsr, you have lowering lower control arms and drop spindles and that resulted in ground clearance issues? I am running 17s and I don't really want to go any bigger than that.

Well I did some more research and it appears that if I want to lower my truck 5 " in the front and use the 3" lower control arms I should use the stock spindles with some lowering springs. That is what DJM has as one of there kits. Thanks for the heads up.

Using those components together violates Scrub. Another words, you get a flat and you loose control since the control arms hang below the rim.
Spindles and LCA's are not designed to be used together. You need a 3" drop spring, or 3" spindles and 2" springs.

I got the 2.5 drop spindles and the 3" drop A arms on 15" 29.5 tall tire and the A arms were about a 1/2" off the ground in the garage.

I'd have to agree. But must admit I have no idea what a scrub violation is.

Basically, a violation is when any frame or suspension part hangs lower than the scrub line of a vehicle. The scrub line is defined as lower part of the rim (i.e. if a vehicle was to rest on its' rims (without tires), no part of the suspension or frame should contact the ground.) It's good practice to set your suspension maintain the scrub line.

Like Chris said, using both dropped spindles and dropped arms are not recommended. (I don't even think 20s couldn't give you enough of a scrub line with the dropped spindle/arm combo.)

not trying to hijak, but would just the 3" LCA be ok with 15's?

Thank you sir! Excellent description. I guess I was a little vague...

It would be fine.
