Kyosho #5000 Diff Gear Grease 15g

The Hobby Hideaway Verdict: Precision Tuning for Maximum Corner Speed! If you want to lower your lap times and carry more speed out of the corners, you need to pay attention to your differential. The Kyosho #5000 Diff Gear Grease is an absolute must-have in your pit box for fine-tuning your drivetrain. Engineered specifically for RC gear differentials, this 5000-weight silicone-based grease provides a medium-heavy resistance that is perfect for preventing your inside rear tire from "diffing out" and spinning wildly under hard acceleration. Whether you are running a 1/28th car on the RCP track or tuning a 1/10 scale basher, this grease ensures smooth, consistent, and predictable power delivery every time you pull the trigger.

Silky Smooth Action & Premium Wear Protection When metal or plastic gears grind against each other under high RPMs, friction is your worst enemy. This premium Kyosho grease not only allows you to tune the locking action of your differential, but it also coats the internal spider gears in a highly durable, friction-reducing layer. It is formulated to resist breaking down under extreme temperatures, meaning your diff action will feel exactly the same on lap 50 as it did on lap 1. The convenient 15g jar is the perfect size to keep in your tool bag and provides enough material for dozens of differential rebuilds.

Key Features & Technical Specs:

• 5000 Weight Viscosity: Provides a medium-heavy stiffness to gear differentials, improving forward traction and corner-exit acceleration.

• Premium Kyosho Formula: A high-quality, temperature-resistant blend designed specifically for the demanding environment of RC drivetrains.

• Reduces Friction & Wear: Coats internal gears with a protective layer that extends the life of your differential components and ensures silky smooth operation.

• Consistent Performance: Resists "thinning out" during long heat races, maintaining a predictable driving feel from start to finish.

• Versatile Application: Excellent for tuning both 1/28th car gear differentials and larger 1/10 scale off-road or on-road platforms.

• Convenient Size: The 15-gram jar is easy to store in your pit box and allows for easy access when applying to your gears.

Hobby Hideaway Pro Tip: When it comes to packing your gear differential, less is usually more! You don't need to completely fill the diff cup to the brim. Before applying the new #5000 grease, use a degreaser to completely strip and clean the gears of any old, dirty factory grease. Once dry, apply a generous dab to the spider gears and rotate the axles by hand to ensure the grease coats all the teeth evenly. A properly coated—but not over-packed—differential will give you the smoothest, most consistent handling on the track!
