Steering Difference Crown vs Currie kit

I know steering is a topic that has been beat to death... I hate myself for even asking this question, but I have yet to find an answer.

What is the defining difference between the Crown kit and the Currie kit? Is it a better angle or stronger ends?

Currently I have a TJ with a 3in lift and 35 km2's (Metalcloaks). I've had the crown kit on for about 8 months and it has had dead spots/wandered for about 6 months. The steering just doesn't feel tight. It actually felt tighter with the stock steering (I ran it that way for about a week to and from work).

Bottom line: Am I going to have the same steering feel with the Currie Kit? Looking for someone who has run both kits if possible.

I have the crown, have run on 32" and 33"s, stick height and now lifted. The only issue I've had is when Discount aired my tires to 38 PSI after my free rotation. Felt like a dead/wander at center. Zero problems at correct (28 for me) psi.

The difference between the Crown and Currie is strength, period. The Crown is OE strength, the Currie is massive strength and good quality. Like comparing a '98 pound weakling to a power lifter.

They both have the same factory geometry so you wouldn't feel any difference between them while driving with everything else being equal.

Well I think they mean the crown HD which is a cheeper version of the Moog ZJ upgrade so it is a fair bit stronger than stock TJ but a notch below Moog ZJ upgrade and well below Currie in strength and price

But still I would rather have my tie rod bend before my knuckle or steering box frame mounts

I Kinda like the idea of a cheeper easier to replace part being the weakest potentially sacrificial link in the chain

But I am not trying to take the hardest trails to see what might get broken but if I did I would probably take your advise and go Currie

Currie's tie rod is specifically heat treated to bend just before anything further up would break. I've bent my Currie tie rod slightly 3X over the past 15—16 years on extreme rock crawling trails but nothing has ever broken. A press straightened it back out. I now run Savvy's Ultimate tie rod and while it can bend if it needs to, it straightens itself back out.

How does a bent tie rod straighten itself out? What sorcery is this?

The same way a spring compresses or bends and returns back to its original shape. The right steel and the right heat treatment, no sorcery at all.

First there is an elastic deformation then if you bend harder you get a plastic deformation but as you as you stay in the elastic range it springs back

Same is true with a metal ruler a little force it bends and springs back when you release but bend to hard it stays bent

Thanks for the reply's everyone. I think you've answered my question. To be clear, Its the Crown HD kit not a V8 zj kit. I wanted to replace all the TRE's when I did the kit last summer. The steering just feels delayed. I just checked to see if I could move the tie rod with my hand, and I can wiggle it. Maybe I've destroyed the TRE's already? I've aligned it myself, I've had a shop align it. Seems like its just "floaty" no matter what. I've got to point the steering wheel one way or the other to keep it going straight.

The tie-rod end is mounted onto a ball joint so you will be able to rotate the TRE forward & backward around the ball joint. There should be no side-to-side play though.
