Mid Travel BS 2.0

No problem. The whole reason you have to replace the UCA is to bring suspension geometry back into alignment specs, which the SPCs do sufficiently. The difference being that the Uni-ball UCAs offer a little more angle than the ball joints on the SPS do, which is good for mid-travel coilovers. But the ball joint is good enough, unless your purpose includes jumping your truck.

 

Hahaha yaa nope definitely don't intend on it being airborne at any time, but who knows crazier shit has happened. Thanks again for all the info bud

 

The other issue is the extended travel. This gives you about 3/4" more extension on the shock, which will almost certainly be more articulation than that ball joint (or truthfully most Uni-Ball) arms can handle. The result is you're using the Ball Joint as a limit stop for down travel, how bad this is depends on how often and how hard your front tires come off the ground. Limit straps are the answer if it's a problem.

All that said, lotsa folks using SPC arms and extended travel coil overs, not many (I can't think of any) people complaining about breaking shit, so you're probably OK.

 

Awesome definitely appreciate thee info, and ya some day down the road I may up grade to a uni ball but for now definitely glad to hear there adequate hahaha. Thanks again bud.

 

when i had SPC arms i found this to be a nice part about having them. The ball joint is lower than the mounting point of the Uniballs so it allowed for more lift and travel. I had to de-crank quite a bit when i swapped to Uniballs.

By allowing more lift im simply meaning i was able to crank more than with uniball arms because the position and location of the BJ. They didnt add any lift, simply allowed me to crank for more height without being severe angled.

 

Interesting. There is no good reason I know of not to adjust the angles of the ball joint or uniball to make the joint not a limiting factor in articulation.

I think people use the joint to limit articulation because it prevents damage to the CV by over extending it.

 

100% agree. I just kept going until it was an issue for more height. But when i switched to the uniball arms i realized i was way over cranked.

 

I made a custom set of uniball misalignment spaces for my Upper arms, and then added limit straps to prevent binding in the CV. The real issue is total down-travel, not ride height.

I took my truck out for the first tail of the year, after all the work was completed, and I had an issue. The UCA is hitting the coilover spring, but only on the driver side.

What causes the UCA to hit the spring? On the passenger side it has at least .5" space, while the driver is basically resting on the spring.

 

Are both sides drooping the same amount? It may be that the difference in how the alignment cams are set gives one side room and the other hits. That would mean something else is stopping the down travel on the passengers side.

 

Yea, the issue is at ride height... I have the coilovers cranked right now and was taking it on a moderate trail to see if it would settle some. The drivers side is resting on the spring while the passenger has plenty of clearance.

 

What control arms are you running?

How much lift is on those things?

Since you've got adjustable UCAs, is there a difference in how much thread is showing on the adjustments?

 

I haven't adjusted them yet, and I do not see any threads visible. I've had them on for about 3 trails and about 600 miles. The latest change I made was swapping from a 600lb spring to 650lb spring, on my Fox coilovers. The shittest part for me is when I dropped off my truck to have majority of the work done last year, the shop lost the adjustment/alignment bar for the heims.

I'm thinking the direction you're going is correct. I'll need to call Rokmen, see if I can get the alignment bar, and figure this out.

 

Interesting problem, and shitty from the shop. I'd check the symmetry on top and bottom between the two sides.

You can fix the coil issue by adjusting the heims out, but that will screw up your alignment if you cant also adjust the LCA out.

 

Hey @BigRedToy the exact same thing was happening to me a while back, idk what your running up front but when I did my 5100 I brought it to a local shop to compress the springs and the dumbass put the coilspring seat upside down which gave me like 4 1/4 inches of lift which made the coil rub up against the UCA.

 

You try rotating the coil so the UCA ends up inbetween coils?

 

FFS....
