Hot RacingSCX10FT01 15mm Wheel Hub Extensions with 12mm Hex (2) - Axial Scx Wraith

These are very much worth the money. As with any Hobby so slight modifications were Necessary to achieve the proper fit. They will fit the Remo Hobby 1093 Crawler after drill out the stock axle shaft holes. And Drill out the Stock Rim holes to accommodate for the new Hub screw. Solid product with through the shaft Screw in Hex Pins. Loctite Everything!! 4 out of 5 because of Mods!Pic two is right side with extensions left without.

Although not designed for a Traxxas Hoss I figured both have 5mm axles and 12mm hex so why not? The only modification to the part really needed is to bore out the inner "lip" with a drill as it wont slide all the way onto the Hoss's stub axle. I also filed down the small protrusion around the axle pin cutout to make the face flush thus creating more clearance for the bearings to avoid anything binding up. Not sure if this 2nd mod was needed but rather safe than sorry. So far so go! My son as ran a few packs through the "widened" Hoss and it looks and handles much better. It's really hard to flip now on pavement at speed and still tracks straight. Also no more rubbing the tires on the body on full compression. You kill two birds with one stone with this mod if you have plastic hexes - replacing those with locking aluminum hexes is a good upgrade for any RC and this kit does that too. Great $20 mod!1st pic - installed! Now 30mm wider than stock2nd pic - only left side installed to show difference vs stock3rd pic - only front axle installed vs stock rear axle

Edit 10/18/2020: Finally bent one! Barely. From a nasty wall drop that snapped 2 aluminum links AND the long steering link. Ordering 2 more sets now. Cannot believe they handle the beating of a 10.7lb all metal capra running brushless 3800 6 pole now on 4s lipoh! I'm blown away by the value here.These are absolute 🔥. Went from 1.9 to 2.2 wheels and needed the width - its perfect btw. I thought they would snap easily as they are the last torque bearing part before rim. I'm running a 9-10lb Axial Capra on 2.2 with castle bushless slate 2850/mamba x and protek 650oz servo. I've gone through 2 ALUMINUM front axle housings (broken from jumping this monster) and these little hot racing spacers are still perfect. Solid.

This was designed great but not with the intention of fitting the traxxas 2021 bronco. Had to modify it quite a bit for them to fit.

Bought several sets of these now for various RC trucks. Always have to drill them out to get them to fit, not a big deal. I have also purchased several sets of cheaper brands and the main difference is the nuts. The cheaper brands use a shorter nut that is very weak, have snapped several.

Got these 15mm spacers because my aftermarket aluminum injora wheels I purchased were rubbing on the portal hubs for my scx 10.3. Quick easy install. Was able to run, stage 2 prolines, with hyrax 1.9 tires. Also gave it a better “bulldog” stance with these spacers. Improved my crawler and has not compromised performance. 10/10 would buy again!

Great product, It's not the first time I buy these hub extensions!! Shipping was awesome. I received the items in less than 48hrs.

Another great buy from horizon. These extensions are top notch parts.
