Adjustable LCA's - Wow!

I put on my RK 2.5" stock mod last Spring. I pieced together the other parts - Poly brackets at both ends, JKS trackbars, etc. I bought some adjustable control arms but didn't get around to installing them. So essentially, I was driving on a Stock Mod. It rode well, but was definitely squirrely in the steering. An alignment helped, but not completely. It still was not confidence building. Wife didn't like it. I just got used to it.

This Fall, I started getting Death Wobble. Not super bad, but it was getting worse. Ball joints checked out OK, but this was another sign that I needed some time under the Jeep.

I put the Front LCA's on this week. Still have Front UCA's & all 4 rears to put on. So I'm almost running a Max Travel lift. I gotta tell you - the front end feels completely different. The steering feels tight again, the death wobble is gone, and it drives like a dream. And I still have more arms to put on!

If any of you are wrestling between the stock mod & max travel - go get the max travel. You won't regret it.

Good for you! Getting that pinion angle right is important. But I doubt that its the cause of your DW unless your old arms has loose bolts.

Could have been blown bushings from funky angles on his stock lowers.

I'm glad you posted this- I've been in the market for the 2.5 max travel and have been considering the stock mod to get me by. With so many reports of the adjustable lowers improving the ride/steering so immensely, I'm going to hold tight and jump straight for the max travel. Do it right and do it once.

No, not the cause of the DW, but it definitely helps eliminate the onset of it. I did several other things while I was under there (including installing the Cam Bolt Eliminators on my trackbar) - I'm sure all of those helped. But I'll tell you what - it makes a big difference.

I'll be building a PR44 after the Hemi gets installed - that will be the Pinion Angle Restoration Tool. (PART(TM))

For now though, it drives a ton better. I wish I would have done this from the beginning.

If you're shopping for a new lift, I'd say go with what you can afford, but if you don't get new LCA's right off, plan on putting them on within a payday or two of that lift.
