I see polyperformance has a weld on 4-link rear "weld-on" kit and a front 3-link kit, for Jeep TJ's... Has anyone used this system and is it designed properly ? Im still new to all these 4-link formulas like anti squat etc. If I buy this system is it going to be the ideal set up or am i better off building my own brackets etc. The kit looks like it would save me some major build time and take out some of the guess work. Also are the 2" .250 wall DOM lower links strong enough ? Id probably go with the heat treated 4130 option anyways. And probably "all adjustable links" Any pics or opinions would be greatly appreciated.
