I had the old Rock Solid Performance sector shaft brace version 2.0 ( I think ), but after swapping out to new coils and using an Artec raised track bar mount the SS brace was hittin the track bar when I put the jeep back on the ground. So I removed it and went without one. Since then I have got a nice clunking sound coming from my steering box. I have recently acquired everything needed to do a hydro assist but before I do it I am going to send my box to West Texas Offroad to have it rebuilt. I want to get a new sector shaft brace to install on my freshly rebuilt box I'm just not sure which brace to buy. I'm very partial to anything Synergy but there website says it will only work with there track bar, but I have a Rock Krawler track bar. I would use the Rock Solid SS brace but I'm not sure if the new upgraded version ( 5.0 ) will work with my application and I won't use the JKS one because I don't like there products ( just my opinion ). Sk my question is what do you guys use and what is your application. Thanks in advance.
