CV Angles with Perch Collars

ameration · Jun 19, 2018

Could any one post some pics of the CV Shaft angles after adding the 1.5” or 2.25” perch collars?

Thank you.

Any one have pics that they can share? I had a leveling kit on my previous F150 and it prematurely wore out the ball joints, had the CV’s at a steeper angle, etc....

The preload collars do not change the suspension cycle like the leveling kit in your F150 did.

It is still in the same exact positioning as factory, thus CV angles would be irrelevant.

They don’t change the swing but they change the angle, hence the lift. It’s that increase in angle that accelerates wear.

For the OP, wouldn’t worry about it. It’s a cool look and in the grand scheme of things they aren’t too expensive.

The "increase" in angle doesnt increase wear if your within the operating range.

Also, the CVs dont spin going down the highway in 2wd, assuming they did increase wear, it would only happen in 4wd.

I have a 2.25" collar and deaver +3 and I've already had to replace my driver side CV joint. The replacement one now makes a knocking sound while in 4wd so I'm bringing it back to dealer. Not sure whats going on.

How do the Eibach springs affect them?

That's incorrect...the new ride height means increased CV angle at rest, but you are correct in that at max droop the stock CV angles are retained...

I'm not a big fan of lots of preload like 2.25"-2.5" spacer lifts..it stiffens up the spring and puts the shock outside of its designed by pass zones...

If you're worried about CV angles, get RCV's.

Any time you modify something outside of Factory Spec, you're gonna have to start to pay to play.

Please, explain to me how adding preload to a spring changes the spring rate, or how many pounds it takes to compress the spring one inch (lbs/in)....

Please note the stock springs are linear.
