They make a 100% difference over the stock sealed bearings that come with the TRX-4M. Its a no brainer replacement, although I am stacking up with transmission bearings for some reason, we need a set with or without the transmission bearings, every set of gears comes with them anyway. If you get this set and expect to replace them all, be prepared to disassemble the entire car, literally. I've been replacing as I go, but I noticed that there are some that are more labor intensive than others. The front axle bearings, in particular. It took me some time to strip down, clean and reassemble the entire front end to replace these. The transmission bearings took some time too, so I saved those for when I rebuilt the transmission, they of course went in easily and worked very well over the stock bearings. I would and will buy these again and would recommend them to others, 100% Review: Great set of bearings - These are a great upgrade for your TRX-4M. They work and fit as they should they are cheaper than the Traxxas set. I will be upgrading all my TRX-4M with these bearings. ## Features - Made of stainless steel - Precise tolerances, sealed and dustproof design - Replace the stock bushings with bearings - Make your rig roll smoother - Contains all the bearings for TRX-4M - AGE RECOMMENDATION: Not for children under 14 years ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BP2BB3VB | | Bearing Number | 22 | | Bearing Type | Ball Bearing | | Best Sellers Rank | #46,713 in Toys & Games ( See Top 100 in Toys & Games ) #1 in RC Engine Bearings #20 in Hobby RC Crawlers | | Bore Diameter | 0.5 inches | | Brand | INJORA | | Brand Name | INJORA | | Compatible Lubricant | Grease | | Customer Reviews | 4.8 out of 5 stars 618 Reviews | | Item Dimensions | 3.15 x 1.97 x 0.79 inches | | Item Thickness | 2.5 millimeters | | Item Weight | 0.03 kg | | Item dimensions L x W x H | 3.15 x 1.97 x 0.79 inches | | Manufacturer | INJORA | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model | TRX4M-03BK | | Number of Items | 22 | | Part Number | TRX4M-03BK | | Specification Met | Oem | ## Product Details - **Bore Diameter:** 0.5 inches - **Brand:** INJORA - **Item Weight:** 0.03 kg - **Item dimensions L x W x H:** 3.15 x 1.97 x 0.79 inches - **Material:** Stainless Steel ## Images ![INJORA 22PCS Steel Sealed Bearing Kit for TRX4M Upgrade, Black - Image 1](https://m.media-amazon.com/images/I/61fQFfPvimL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great value for the money *by D***W on October 18, 2023* Not sure the tolerance of these and I cannot tell the difference between these and the Traxxas branded set, so I will most likely get these again in the future.
