Gen 2 Converted Gen 1 CV Problems

SilverGen1 · Jan 6, 2025

I did the gen 1 to gen 2 shock conversion on my 2012 Gen 1. I have pretty extreme cv angles, and have been tearing boots like no one's business. I plan on adding limit straps, similar to the old evil offroad one, I would be fabbing it up myself. My question, what else can I do to help prevent tearing more boots and ruining cv's? What have you guys done?

So, you replaced the Gen 1 factory 2.5 Foxes with the longer Gen 2 factory 3.0 Foxes, retaining the original coil buckets?

They aren't interchangeable.

The boots are getting destroyed by the extreme angle caused by the longer gen 2 shock. You either have to change the upper shock mount with one from khc customs, or get creative like https://www.fordraptorforum.com/threads/ogs-method-of-2gen-shock-swap.81344/

I saw OPs other post and I believe he already has the coil bucket conversion.

Op, I've have a 2g conversion and I changed the internal top out spacer from a 1" to a 3/8" thickness which gives the shock 8-5/8" of shaft travel, it drops pretty far.

Some pointers I have are:

The cv axles them selves, I'm using the extened travel ones and they seem to be holding up, but I have noticed that the bellow on the outboard side flippled direction, or over centered so it's collapsed inward.
It was like this for a while and I could tell it was wearing in this position, since I found that I have been cleaning and lubing the bellow with silicon spray often it seems to keep the rubber from popping inward.

Another item to consider is to take out negitive camber if you can, I'm not saying go positive but go as close to zero as you can. Depending on your front ride hight the camber curve will definitely cause an aggressive cv angle at drop especially if it's already negitive at ride height. Having the front higher up at ride height with zero camber will reduce the total angle at drop as well.

And lastly when in a turn with steering angle and the front drops the cv angles will be extreme no matter what, so along with other reasons I do recommend keeping a front swaybar. This will give you full travel for head on hits but much less flex and thus your steering angle will not be as hard on the cvs in most cases.

To summerize,
Negitive camber at ride height will cause more cv angle at drop.

A higher front with the same camber setting will reduce cv angle at droop.

Swaybar will help save the cvs while steering in flex.

High Angle Inner CV Boot - Products - Off Road Solutions

These CV boots have been completely re-designed to work with high angle applications, such as lifted vehicles. They are made from silicone material, making them very resistant to the heat and friction created w/ high angles. Kit includes 1 boot, 2 clamps, and CV joint grease. 2 kits are needed...

Yes you are correct, I did the KHC conversion buckets. I am curious to reduce the negative camber, because I definitely do have that at stock ride height. I ended up doing limit straps, and it has helped a lot, but I would be curious to try out some of these other solutions along with the limit straps to help preserve cv boot life. What extended travel ones are you using, the trakkmotive ones? I'll have to look up what the "bellow" or a CV axle is. I am pretty sure I have seen your thread on changing the spacer as well, so that gives you "more" up travel? Really just moving the entirity of the travel up?

Swaybar should help save the cvs while steering.

SilverGen1 · Mar 7, 2025

Yes i also still have the swaybar attached

Just an FYI. The KHC buckets will reduce clearance to the brake lines on the D-side, and to the engine itself on the P-side. Also, the spark plug behind the P-side bucket is still technically accessible, but you'll need to pull the shock to get to it.
