I love Injora! Review: Really nice, but not compatible with stock bushings - Please read my entire review: Quality of these things is crazy for the price. The gears seem to be hardened as well from what I can tell, gear mesh is pretty decent and no binding! Love that these are helical gears similar to real trucks. **As the title states, theses are not compatible with the stock bushings. The differential shoulders are knurled to grip onto the inner race of the bearing kits. Obviously if you decide to run the bushing and go against my advice you will end up with either severe binding or badly worn differential carrier bushings. Buy any bearing kit with this purchase. Some modification is required** So now the pinion bearing fit is extremely tight and you will not be able to slide the pinion down onto the bearings as intended. To remedy this I chucked the tip of the pinion gears. Onto my drill gently and with a tiny sliver of 800 grit sand paper, spun/sanded the shaft/ bearing fit down so to resolve this issue. At medium speed with 800 grit this took less than 1 minute of sanding/spinning and voila. Done. I had fast eddy bearings, results may vary. ## Features - Replace the stock plastic gears, fit TRX4M front or rear axles - Helical gears offer greater strength and smooth operation than the factory spur gears - Less vibration, less noise, less wear then stock gears - CNC machined 20CrMo Alloy Steel Gears - It does not change the speed of the car, Suit for 1/18 RC Crawler Car TRX4M Upgrade Parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BR3SCCMP | | Age Range Description | Kid | | Best Sellers Rank | #91,947 in Toys & Games ( See Top 100 in Toys & Games ) #39 in RC Vehicle Transmission Gears | | Brand Name | INJORA | | Customer Reviews | 4.4 4.4 out of 5 stars (265) | | Educational Objective | Game, play | | Is Assembly Required | No | | Item Weight | 0.02 Kilograms | | Manufacturer | INJORA | | Manufacturer Maximum Age (MONTHS) | 144 | | Manufacturer Part Number | 4M-10-24T2 | | Material Type | Alloy Steel | | Number of Players | 1 | | Operation Mode | Manual | | Power Source | Manual | | Set Name | 2-pack | | Size | 2PCS | | Supported Battery Types | No batteries required | | Theme | Car | ## Images ![INJORA 24T/12T 6g Alloy Steel Helical Gear Set for 1/18 TRX4M Front Rear Axles(2PCS) - Image 1](https://m.media-amazon.com/images/I/51cl77Y6VhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install and great fit *by M***R on September 2, 2025* Really good gears!
