First batch TC8 kits are expected to have a snug fitment on the inner suspension arm pivot balls. We highly recommend using this reamer to enlarge the holes in the arms as needed to remove any bind from the suspension. Helpful tips from Schelle: Another drop for Team Associated users, get those pesky 5.5mm rod ends cleaned up and freed up. 5.5mm round ball tip for Associated CNC machined, black anodized handle Needs open-top eyelets, or you can cut the tension screw to use in other closed joints. Popping into a ball without the srew will collapse the ball. Fits B74.2, T6.4, SC6.4 series, any open top eyelets. *** MUST READ: Don't pop off across/perpendicular to the slot or it will bend sideways. Due to the direction of the cutting slot, you must rotate and pop out in-line with the slot. If you want to avoid scratching the cups, you can remove the screw each time out of the end when popping off **My pro tips: I install with the screw hand tight (it keeps it from collapsing) and remove the screw to pop off so it doesn't knick the opening of the cup. Usually pull down as you ream as the bottom opening is where I found most drag. To avoid damage or bending the 2 ears, align the slot with the rod and twist off in the same direction, not across the slot which bends the ears
