As many of you know I was one of the pioneers in the 52" front spring swap one year ago. I probably made the mistake of putting the late model 52's up front under my truck, had a helluva time trying to find bushings. I ended up contacting Az-Kickin Off road in AZ to have him make me some out of UHMMV, talk about harsh ride, but they are very very durable. I also found that the 52's work great in just about every possible situation, but need very good shocks to work with them. Im running the Sway Away Race Runner 14" travel shocks and they actually dont have enough travel to keep up with my front suspension, so my suspension is limited to around 13" of pure vertical travel. This seems to work very well with the shocks and springs, but when things get articulated I can achieve almost 20" of travel, but im not too sure since ive never measured it. Overall, im happy with the results, and not impressed at the same time. The travel is excellent, but the excessive travel, and stiffness of the front spring bushings has killed my frame. Its also made me take my truck places I shouldnt have been and caused it to get smashed. Nearly 2 months after I got them on I smashed the hell out of both quarter panels, then a little bit later I smashed all the panels up. Oh well, it happens, the front fenders are broken anyway from excessive frame flex.
