Caster Adjustment
Like the others have said already you'd be better off going with adjustable arms. Not only will they grow with you they will allow your caster to be dialed in just right. Not all jeeps are the same so having the ability to adjust is nice. Rcck Krawler, TeraFlex and Metal Cloak all make great arms and the price isn't that far off from what you were quoted already. If your really set on fixed arms I've heard good things about the JSPEC arms. Good luck.
I will agree with others here. While the fixed arms are going to be an upgrade, there are subtle differences between rigs, even those of the same model year running the exact same gear. While those fixed arms will likely work fine for you, they will not allow you to fine tune and truly dial it in. Plus, an adjustable CA will allow you to make changes later down the road. You can get budget adjustables for the same price you've been quoted for fixed. A few extra bucks and you can get some of the bigger name ones.
Oh... and them cam bolts is the devil.
All of you have some great points. I guess it looks like adjustable lowers are the place to start. So now to find the best bang for the buck on a good set. Thanks everyone for you help. I look forward to getting this thing in the road.
All you need are the adjustable front lower control arms to adjust your caster. You won't need the rear uppers unless you add an aftermarket drive shaft in the rear. You can pick up some nice front lowers for less than $300. Take a look at RK...very heavy duty.
