Magnum force UCA

Anyone install magnum force upper control arms? If I’m looking for more caster I think I have this on correctly
Also do I need to trim this back so it doesn’t hit?

I don't think that anyone ever has. There have been many sold but nobody has ever installed any.

The install looks right. With stock UCAs, the rear mount is lower than the front but the ball joint pad is tilted to sit almost level. This is part of the stock "Anti-Dive" geometry that imparts some stress to the ball joint in the process of resisting compression under braking.

Regarding that nub under the arm, only trim it if it looks like it will make contact under full range of the suspension.

Yes trim that corner off of there, make a nice 45* cut.

Thanks I’ll probably wait to trim until I get the car on all 4.

I ran Magnumforce UCA's with Moog K7103 offset bushings for awhile on my Duster before switching to SPC's. With the Magnumgforce UCA's and offset bushings I was able to get as much as +8° of caster (I run the car with around +6.5°).

You will need to cut that tab on the UCA mount back some to clear the Magnumforce UCA's. It's necessary with all of the tubular UCA's that use a tight "V" shape, you just need more clearance. It's MUCH easier to make the cuts with the car in the air and the UCA's off the car, so, I would just do it before you put everything back together. It has to be done, and if you do it carefully it won't effect the strength of the mount any. First picture shows the area to cut, second picture is the actual mount on my car after it was trimmed back for clearance. It's cut back further than it needs to be now, but I did the cutting before I resized my torsion bars up to 1.12", lowered the car further and resized the bump stops to recenter the range of travel around the new ride height (shorter lower bump stops, taller upper bump stops). With stock upper bump stops you'll probably need to take more off than just the corner at a 45° angle, I know I did.
