Upgrade your RC car's drivetrain with a durable steel metal spur differential gear set. This kit includes multiple pinion gear options to help you fine-tune your car's speed and acceleration for better performance on any surface.

These replacement gears are crafted from high-quality steel for long-lasting use. They are designed to fit a wide range of popular HSP and Redcat RC car models, making them a versatile choice for hobbyists and DIY enthusiasts.

Whether you are rebuilding a broken drivetrain or tuning your car for a specific track, this gear set provides the essential parts you need. The included gears are built to handle the demands of high-power brushless motor setups, ensuring reliable power transfer run after run.

Get your RC vehicle back on the road with confidence using these robust metal gears. They offer a simple and effective upgrade for both casual drivers and competitive racers.

Key Features and Benefits

- Made from high-quality steel metal that provides superior durability and resistance to wear for longer gear life.

  • Includes multiple pinion gear sizes (17T, 21T, 26T, 29T, 64T) that allow you to adjust your gear ratio for more speed or more torque.
  • Designed as a direct replacement that fits a wide range of HSP and Redcat models for a hassle-free installation.
  • Features a standard 3.17mm shaft aperture that ensures compatibility with common RC motor shafts.

Who Is This For

- RC hobbyists who need a reliable replacement gear for their HSP or Redcat model.

  • DIY enthusiasts who enjoy tuning and customizing their RC car's performance.
  • Racers looking for a durable steel gear upgrade to handle high-power brushless systems.
  • Anyone performing a drivetrain rebuild or repair on a compatible 1/10 scale RC car.

Usage Scenario

After a hard day of bashing at the local park, Tom noticed his HSP 94111 was making a grinding noise. He found the plastic pinion gear was stripped. He ordered this steel gear set, swapped out the damaged part with the 26T gear, and was back to running full speed laps in under 20 minutes. The steel gear held up perfectly against the rough terrain and high torque of his brushless motor.

Micro Comparison

While plastic gears are lightweight and cheap, they often strip under the high torque of brushless motors or aggressive driving. This steel metal gear set provides the strength and longevity needed for serious RC use, making it a more reliable investment for anyone who drives their car hard.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

Baby bumps and bodyguards
Format: Kindle
Dark, emotional, and unexpectedly tender, Not Ready is an omegaverse romance that delivers found family feels, fierce protectiveness, and a very pregnant heroine who refuses to break. Vale’s on the run from a stalker, but lands in the arms of three private security alphas, cue the swoony tension, fake marriage twist, and slow-burn heat. It’s a little gritty, a little soft, and a whole lot addictive. If you love protective alphas, high stakes, and heroines with quiet strength, this one’s a must-read.

Strong Omegaverse Comfort and a Attention Grabbing Plot
Format: Kindle
Jillian West never misses when it comes to Omegaverse, and Not Ready is no exception. This story was the perfect blend of cozy comfort and emotional depth while still delivering a strong plot. Vale is such a powerful heroine, she is strong, capable, and determined but I love that she still allows her pack to love and take care of her. It’s that balance of independence and vulnerability that makes her so relatable. The relationship dynamics were amazing: Bishop is steadfast and completely head over heels, Mercy is skeptical but protective in his own way, and Holt is the hesitant one whose slow fall is so satisfying to watch unfold. The romance hits that sweet spot between insta-love and cautious build, keeping me hooked the entire way through. And that ending. Oh my god, the cliffhanger! I need the next book in this duet immediately.
