RC enthusiasts, listen up! If your Traxxas E-Revo EVX-2 is starting to sound gritty or isn't rolling as smoothly, it's probably time for new bearings. This FastEddy bearing kit is made specifically as a replacement set for that model. The kit includes a variety of sealed bearings in the sizes you'll need: (4) 12x18x4mm, (4) 6x13x5mm, (6) 6x12x4mm, (2) 10x15x4mm, (2) 8x16x5mm, and (14) 5x11x4mm. Sealed bearings are great because they keep dirt and grime out, which extends their life. BUT – and this is important – always double-check your specific RC model and any aftermarket upgrades you've installed. Manufacturing changes and hop-ups can sometimes mean different bearing sizes are needed. If you're unsure, it's best to check your truck or contact the seller to confirm this kit is right for your exact setup. FastEddy is a trusted name in the hobby for quality parts, so this is a solid choice for a maintenance overhaul.
