RC enthusiasts, listen up! If you're running a Losi Polaris RZR Rey side-by-side and your bearings are getting crunchy or you're doing a full rebuild, this FastEddy bearing kit has everything you need. We're talking about a complete set of sealed bearings that'll replace all the factory ones - includes (4) 3x6x2.5, (2) 5x10x4, (2) 5x11x4, (2) 5x13x4, (8) 6x12x4, and (6) 10x15x4 sizes to cover your entire vehicle. These aren't cheap, no-name bearings either - FastEddy makes quality stuff that holds up to serious bashing and racing. The sealed design means dirt, dust, and water have a harder time getting in there and wrecking your smooth rotation. I've used these in several of my own rigs and the difference in how everything rolls is noticeable immediately - less resistance, smoother operation, and better overall performance. Just a heads up though - always double-check your specific model and manufacturing date before ordering, since bearing sizes can sometimes vary depending on when your RC was made and what hop-ups you've installed. The photos are just for reference to show the bearing style - you're getting the exact sizes listed. Installation is straightforward if you've done bearing replacements before, and having the full kit means you can do everything at once instead of waiting for multiple orders. Whether you're maintenance-minded or your bearings are already shot, this kit will get your Polaris RZR Rey rolling smooth again!
