Crazy strong. 1.5" thick solid stock tie rod. I don't worry a bit about bending anything on the rocks. I think the knuckles or the grade 5 bolts will go before the tie-rod will. Strongest kit I've ever seen. The cross-over design gives a firmer feel to the steering wheel on Jeeps with tall lifts.
On the downside, the kit uses rod-ends (heim joints). They're more likely to get contaminated and squeek than tie rod ends, but I havn't had any problems yet. Since the drag link uses a rod-end on the axle end, you have to adjust your steering stops a little so you don't max out the joint and bend the .25" thick boxed bracket. You lose about a foot or two of turning radius. On a SWB, I don't feel it's much of a concern though.
The install was very easy, only thing you have to do is drill out your knuckles a little to fit the bigger bolts through. Takes about 10 minutes. Adjusting for toe-in/out involves taking off at least one end of the tie tod, and twisting in the rod-end, just like you would a control arm. Centering your steering wheel is easier.. loosen the jam nut and clamp, and turn while it's still on the Jeep.
I havn't experienced any bumpsteer with this kit, so I havn't even added a steering stabilizer. I have RK's 5.5"LA with a dropped track bar bracket, dropped pitman arm, and this steering kit.
I'm very happy with this kit. I was torn between RK and Currie's kit when upgrading my steering. I went with RK's steering for the additional strength, the crossover design, and the lower price tag. Would buy again.
