Nick Esposito Verified Owner Wednesday, Feb 21 2024 (about a year ago) MST RMX 2.0 alum. spur gearbox driving set (red) night and day difference compared to the stock bevel trans Brian Verified Owner Monday, Feb 27 2023 (about 2 years ago) MST RMX 2.0 alum. spur gearbox driving set (red) Not just a beautiful addition, but the internal change from the stock RMX 2.0 transmission is beyond words. Great upgrade, great quality Anonymous Verified Owner Saturday, Feb 4 2023 (about 2 years ago) MST RMX 2.0 alum. spur gearbox driving set (red) I can recommend this set. Bought it as replacement for the stock transmission on my RMX 2.0. Michael Gonzales Verified Owner Wednesday, Feb 1 2023 (about 2 years ago) MST RMX 2.0 alum. spur gearbox driving set (red) Exactly as described and fast shipping. Good quality item ,would recommend.
This is an awesome upgrade and was quite fun putting together but I wish it would’ve recommended or come with the 42mm CVD shafts as the stock length are too long and bottom out in the ball diff outdrive cups. Lemar Andres Verified Owner Friday, Jan 27 2023 (about 2 years ago) MST RMX 2.0 alum. spur gearbox driving set (red) Is a must for upgrade. But hopefully next time i buy it comes with driveshaft lol Walter Alexander Saturday, Oct 15 2022 (about 2 years ago) MST RMX 2.0 alum. spur gearbox driving set (red) Super smooth in feel and transition of power. Just bought a second to goin my sons chassis. Worth every cent. I’d take a half star off if I could as it doesn’t come with the bearings for the outdrives. You can harvest them from your stock transmission, or support your local hobby shop and pick up a couple new ones.
