3 inch DJM Spindles - my rims hits control arm

I just got done putting them on and the rim hit the lower control arm! It say to trim a little but WOW! The are hitting with the wheels strait! I wonder how much I need to trim off to turn....... So my truck will be down till my next day off work!
Any suggestions or pics of the trimming involved??
Thanks guys

Whatcha workin on? What wheels? Shouldn't have to trim anything

on my 1999 C3500 4 door long bed 454 NON Dually. The stock rims dont fit on the front, they are hitting the lower control arm! ill take some pics and post them up.....................

stock 16" rim hitting the lower control arm............

Start trimming the lower arm a little at a time or look at buying some larger diameter rims. After trimming weld some plate on the bottom to strengthen arm.

I've seen that happen on 1/2 tons. Cut too much without reinforcing and the arm will bend.

i wish i knew this before i ordered them! im not gonna trim the lower control arm because im gonna run some 20's. looks like ill put off buying my bag parts to buy some 20's.

This is a common problem on the SRW Chevy trucks when you install certain spindles/arm combinations. Most of the companies suggest running a 18" wheel or bigger when running them on these applications.

this wont happen when i do the 6/8.5 western drop to y dually?

Shouldn't have a problem on a dually, I would stay away from the western chassis front kit as they use a 2" spindle and a 3" spring unless they have changed to a 3" spindle now. That way if you go lower later and wanna lay frame you don't have to buy new spindles
