I just installed a Synergy tie rod this afternoon. (Bent the OEM.) Pretty straight forward install, but a bit unorthodox set up with the ends. The passenger side is Loctited and then set by a jam nut. Uses Poly's trick double adjuster that they use on their control arms & track bars. Worked well. The item is very stout and can take a lot more of a beating than the stock one. The ends are GM 1 ton units, easily obtained at NAPA, etc. I had a Poly drag link at one time but swapped it out for a Teraflex. I may put it back on, wasn't happy with the double adjuster in that application. Wouldn't stay put. Got some new ends, GM 1 Ton for the knuckle and a Moog for the pitman. The TF unit is basically a RHD stocker flipped over for high steer. Pretty wimpy compared to the Synergy, but plenty strong enough and easy to adjust, same as stock.
