Hey there, RC enthusiasts! Got a Tamiya Toyota Blitz (TA02 chassis) that needs some smoother rolling? This FastEddy Sealed Bearing Kit is here to upgrade your ride from those stock bushings. The kit includes all the bearings you're likely to need: (2) of the 10x15x4mm size, (12) of the 5x11x4mm, (6) of the 5x8x2.5mm, and (2) of the 6x12x4mm. Swapping these in can seriously reduce friction, giving you better speed, efficiency, and a quieter drivetrain. Now, a super important heads-up: bearing sizes can sometimes vary depending on when your specific model was made or if you've added any aftermarket 'hop-up' parts. So, before you click order, it's a really good idea to pop open your chassis and double-check which bearings you actually need. We try to keep our kits accurate, but Tamiya has made changes over the years. If you spot a mismatch or have a question, just give us a shout - we're happy to help sort it out. Installing bearings is one of the best and most affordable upgrades you can do. This kit has quality sealed bearings that'll keep dirt and grime out, making your Blitz run like a dream on the track or in the backyard. Let's get that thing rolling smoothly!
