Sold as two bushings, washers, and a sticker.
APS stands for Animated Polymer System. This urethane is very lively giving you more turn that a same durometer stock bushing, with lots of rebound. APS doesn’t compress the same as stock bushings and other formulations, so you can take it from the standard just snug washers to a few full turns without effecting the compression and decompression characteristics.
Chubby bushings are like the squished Venom Eliminators without eliminating so much. If your double barrel set up needs just a bit more break from center and stronger return to center then these bushings may make one stoked.
