I didn't like how the Pioneer sat lower on the rear after installing the front lift & front spring spacers . So I made these rear spring spacers over a year ago out of PVC. I made the 3/4" in length.I used 2" pvc pipe and glued a 2" joiner over top of the pipe.then cut the other end of the joiner off and slit it length wise and glued it over top of everything.Sure there is a gap in the outer piece but it didn't affect anything.I made it triple wall so this way the spring is supported really good and everything sits nice on the adjusting ring. I've had set up for a year now and haven't had any problems.
