TM Designworks are top notch and so are GT Thunders, Heres a pic of the TM Designworks, Had them in a 450 and a 660 and they lasted the entire time I owned the 450. They also have a 2 year free replacement. Outlast bronze 8 to 1, and 15 to 35% more contact area, Both Tm's and GT thunder are no stik self lubricating.
i have play in the upper a arms of my warrior. i thought there was just bushings in there but i see pivot works makes a bearing kit for the upper a arms. has anyone tried that? is it needed?
The TM Designworks I got do upper and lower a arms. If you ride hard trails and beat on your quad these bushings are what you want, They will last I promise.
