Losi Promoto-MX Upgrades & 1/4 Scale Parts
The 1/4 scale Losi Promoto-MX is unlike any other RC vehicle — and it demands equally specialized losi promoto mx upgrades to reach its full potential. From chassis stiffening to suspension tuning, our parts are engineered specifically for the unique geometry of the Promoto-MX platform so your bike corners sharper, handles smoother, and withstands the inevitable tip-overs.

Why Upgrade Your Losi Promoto-MX?
The Promoto-MX tips over — that's part of the experience. But repeated tip-overs destroy plastic components fast. Our 1/4 losi promoto mx parts in aluminum and steel absorb impacts that shatter stock parts, keeping you on the track instead of at the workbench. Every upgrade is a direct bolt-on replacement designed to the exact OEM dimensions.
Let customers speak for us
Not sure about durability but works good. Don't know if parts are available either
Not sure about longevity, but currently I'm highly impressed. Super easy bolt on, minimal modifications needed.
For those wondering how different it looks than stock, there's a picture of a 100% stock rig, slightly modified one and the SUPER wide Bronco
Wonderful purchase, love the color, finish and weight. They add a ton of width and spin super smooth.
Worked as expected without issue which is a good thing for me. if you get a defective part i feel like it is not the norm.
Great clearance
Works great so far! Had to make some adjustments but works great.
Big improvement on my SCX 24 Bronco for steering.
These are the best shocks I've found and longest without being those annoying tele shocks that bind up. These are NOT telescoping. They are just larger and longer shocks than stock. You could make these take oil if you sealed the shaft entry. Make sure to lock right the bottom part to the shaft itself. It WILL unscrew after time if you don't. Great quality and great look. Perfect for the scx24.
Much beefier vs stock . Loaded and smoothed
I really love the look and performance of these axles and would definitely purchase them again. The one thing I didn’t like about the axles is that I wanted to replace the actual shafts inside of them so that I can do the +4 mm but for whatever reason the bolts do not come out of the steering knuckles, no matter what. Both top and bottom bolts snapped off on both sides and end up, having to cut a slight slit into the side to release pressure on the bolt and get it out after. It still works good but there is a little bit of playing there now compared to before having to do that but I would definitely recommend them again I just asked that they don’t use maybe a thread locker or whatever was use to put them on because it was very difficult, taking them out, even after releasing the tension and whatever it was was very oily when applying heat.
