      Old thread brought back to life. I'm looking into this right now. I have 35s with plans of switching to 37s. The steering is fine until it isn't. The 3-point manuever to get into my garage seems to stress the OEM power steering. On the rocks, I often loose steering as others have mentioned.

      I've talked to people with the AEV lift that have tried using the Synergy sector shaft and steering box brace but ran into interference problems. Also, that kit is nearly $300 and only helps brace what's already a fairly weak sector shaft.

      Switching to hydro assist solves several issues for $500-600 (WTOR Rdneck Ram kit). It takes most of the stress off of the steering box, sector shaft, and draglink (I think), while also increasing your turning power, and acting as an extra beefy steering dampener. It's also a lot cheaper than bracing, reinforcing all of those parts. Hydro assist is a redundant system. So if you change your mind, or it breaks, you can plug the extra ports in your steering box and go back to OEM power steering.

        I am running the PSC Big Bore Steering Kit on my JKUR with 37s and 5.13 gears. No issues, no leaks, happy with it. I did have it installed at Offroad Evolution when the rest of my lift, axles, gears were getting done. Going to hydro assist is NOT needed unless you go to 40s. Looks cool though.

          It's been a while since I've checked out the forum. Good to see that Panhead and Jadkar are still exchanging good natured insults with each other. As far as adding hydro assist for 37's, I've seen plenty of rigs that have gone that rout and had a chance to drive one. The thing I didn't like about hydro assist is that it takes a lot of the "feel" out of the steering wheel. Personally, I like to know when the wheels are bound up against a rock. I'd much rather back up and take a different line that force my way through something. Even with hydro assist, the force has to go somewhere and there will always be a weak point. That said, I highly recommend that anyone running 37's add a sector shaft brace kit. I installed the Synergy front track bar brace and sector shaft brace kit. https://www.quadratec.com/products/1...tm_source=bing As long as you take off your tires, it's a fairly straightforward installation. One thing that wasn't clear is that you really need to use the Synergy trackbar with this kit. I already had a Synergy tie rod and drag link, so I didn't mind replacing the track bar. Once installed, everything clears and works perfectly with my 4.5" AEV lift.

            Hey, on that synergy track bar and sector shaft brace kit it does work with the AEV lift kits. I have one and I'm running the AEV SC 3.5 lift.

              Jake at NMBR was telling me he had some interference trying to use the Synergy sector shaft brace. And others seem to think it's snake oil since your'e still running what's considered a dinky oem sector shaft. The PSC big bore probably solves some of this. From what I've read, the amount of steering feel lost when running hydro assist depends on the strength of the system. I was planning to use The Redneck Ram 1.5in cylinder set up with the OEM steering box and power steering pump. So that's a pretty minimalist set up supposedly good for running 37s. But I'm still trying to decide if that's the right move. I don't want it to get twitchy on the highway. But I would like to be less fatigued during highway driving (I think my ball joints are on the way out).

              I hear the back up and take another line approach a lot. I'd suspect any of us would do that when you can. Sometimes you can't especially when your steerings jammed up and there's an obstacle in front anf behind you like when I was trying to climb up this winch hill. Of course the photo looks tame but it was probably a 35-degree angle hill filled with loose boulders and 30+ inch ledges. Before the winch came out, I really needed my DS tire on that big boulder and my PS on the smaller rock but I had no steering and was stuck in a hole. Admittedly a rare situation but that trail was full of times, I wish I had stronger power steering and less breakable linkage.

                The only interference possible is that the coils on some lift kits have a very large diameter. AEV springs have a small diameter. I thought it helped with making the steering on the jeep nicer. I will be upgrading to a PSC big bore kit when my power steering fails again.

                  For the price. I'm going to go hydro assist. I'll report back.
