00:00If you've been bashing your ARRMA 6S Kraton hard, you already know that diff slop and
00:04stripped gears are bound to happen sooner or later. Getting your gear mesh tight is the number
00:09one secret to bulletproof reliability, so today I track down the absolute best deals for the top
00:145 ARRMA 6S Kraton diff shims and drivetrain reinforcement parts to keep your rig running
00:19smooth. First up, if you're cracking open your bulkhead to shim things up, you might find your
00:24stock gears already chewed, which makes this 43-tooth spiral diff gear and 10-tooth bevel
00:29gear kit an essential fix. Its CNC-machined hardened metal construction significantly
00:34tightens up gear engagement right out of the box, stopping stripping under sudden 6S punch.
00:40At just $12.09, with thousands sold and a 4.9 Star Trek record, it's the best affordable backup
00:46set to keep in your pit box alongside your shims. Next is the actual holy grail for fixing drivetrain
00:52play, the RKOD diff shim set made specifically for standard 29mm diff cases.
00:58The standout feature here is that it includes precision-cut shims to service all three differentials,
01:03front, center, and rear, eliminating internal gear play so your bevels stay fully meshed under load.
01:09Priced at only $14.99, this kit is easily the cheapest insurance policy you can buy to save
01:15yourself from costly diff replacements down the road. Now, all the shimming in the world won't save
01:20your drivetrain if your center diff flex is under high torque, which is why this CNC metal center
01:25differential mount is such a smart pickup. It locks your center differential rock solid to the
01:31chassis, eliminating the plastic flex that causes pinion to spur separation during hard landings.
01:36It holds a perfect 5-star rating, and for just $7.26, upgrading from weak stock plastic to rigid
01:43aluminum is an absolute no-brainer. While you have your croton taken apart on the workbench for diff
01:49maintenance, you should definitely inspect your seals, and this upgraded sealing ring and oil seal set
01:54is great to have on hand. Made from durable, heat-resistant silicone, these seals provide a
01:59tight, leak-proof barrier that keeps your essential fluids locked inside and abrasive dirt out during
02:04messy bash sessions. Coming in at just $6.10 with a flawless 5-star rating, it's a super inexpensive
02:11way to keep your maintenance downtime to a minimum. Finally, if you want an ultra-premium gear set to pair
02:17with your new shims, take a look at this heavy-duty 43T and 10T metal diff gear combo.
02:23These gears feature deeper, heat-treated tooth profiles engineered specifically to handle aggressive
02:28throttle inputs, skate park sends, and full 6S backflips without skipping a beat. It comes in at $27.07,
02:36which is a bit more of an investment, but the rock-solid build quality and perfect rating make
