I was thinking of replacing my rear lower arm bushings soon with new OEM. I figure about $100 for all 4 bushings and the hassle of finding a press to use and the time to press them in and out adds up. Slee has there arms for $250 for a stronger arm, new bushings on one end and a sealed flex joint on the other. Install should be easy since I don't have to deal with the bushings or and down time to find a press. But how do the slee bushings stack up to OEM for longevity, articulation and vibration? Has anyone used these?
