GCM-BowHouse Diff Cup for SMT10 / Wraith / Yeti

Diff cup for SMT10 With much thanks to our good friends at GCM, we are pleased to offer these legendary diff cup for the Axial SMT10, Wraith, Yeti, Exo Terra and other applications that utilize AR60 style internals. So what's different about these differential cups? Each diff cup includes 2 polished stainless steel shims to isolate the metal-on-metal friction between the output gears and the output bearing area. This allows much cooler bearings and longer life of all the internals. Cases also include a side hole sealed by a grub screw for easy, no-removal oil fill-ups. Simply remove the grub screw to refill your diff fluid as needed without having to disassemble the entire diff, and you are ready to go before you know it. Each kit includes the parts you need for 1 axle: 1x new billet machined diff cup 1x M3 grub screw screw for fill-ups 2x outdrive gear shims Installation notes: Do NOT use the INSIDE o-ring on the new diff cup side. Use ONLY the OUTSIDE o-ring on the new diff cup.
