Your truck looks great! I had previously just installed the same 4.5/6 kit but it is a McGaughys. I am running 20x8 Riddlers on front with 255/45/20 and have some rubbing. What does the bottom of the front fender measure to the ground on your truck? Thanks!!

Sorry, just saw the replies. I have no rubbing issues at all. I'll have to take measurements and post them on fender height at the wheel well opening.
I got the engine dialed in too. It always ran rougher than I thought it should. It wouldn't idle as good as it hoped, it spark knocked at WOT and the starter had trouble starting once warm.
I had backed initial timing out to 0* and still it had issues.
Turned out I was using the wrong mark on the balancer and had about 28 * initial timing in it (face palm). Set it up correctly and now it's a gem of a motor for a DD.

Hey man. Great to hear about your engine! I’m glad you got it figured out. Do you know what the fender lips to ground measurements are on your truck? I like the setup and stance!

Awesome! Thanks. I have the 4.5/6 Mcgaughys kit in mine with 255/45/20 front and I have rubbing issues. Wheels are 8.5 wide with 4.75 BS. Mine measures:
26.75 FR
27.25 FL
I think I need to install 1” springs instead of 2”.
