[quote="H. Badger"]I did see the reviews on the poly said awesome for easy adjustment an the RK was a pain. I have a little wait time till I'm putting it on. But the reviews are definately changing my mind. Pm me, I woul like to talk about the adjustment differences if you didn't mind.[/quote]
Let's talk about that here, so everyone can benefit (unless you have a reason for being private about it?)... not only will you get my opinion, but others can do their best to confuse you as well.
I have not run the RK unit, but I know it isn't adjustable on the rig... the Poly item is. Often times, when you wheel, you'll have alignment issues afterwards and you'll often have the steering wheel crooked. The drag link adjusts the later problem (also a good item is the Poly bit, for the same reasons), the tie rod the former. It is a very simple adjustment, but the RK item requires you to drop the tie rod to do the adjustment. Not a huge deal, but much nicer to do it on the rig. If you go the RK item, you'll have to break that TRE out of it's home each time.... and that can be a bunch of times in one shot, as you likely will adjust, measure, and adjust. So... with the RK piece, buy a BFH.
I believe the RK unit requires you buy TREs as well... so add that to the cost. Poly's comes with them, but you might want an extra as they are a hard item to find in the field. The RK TREs are stock ones that can be found anywhere. Poly and the Internet people state their TREs are beefier... I have not confirmed.
