4Pcs 12mm Wheel Hex Hub 20mm Extension Adaptor Longer Combiner Coupler for 1/10 RC Crawler Scx10 D90(Red

The media could not be loaded.  These are okay if you are a crawler, speed run or even just light off-road but if you are a heavy/hard basher taking big jumps and other stuff like that these will absolutely destroy your wheels/hex slots and will almost guarantee you to bend your axle shaft pretty quickly no matter.Yes I understand that when tightened up the bolt with center in the hex off your axle shaft and will be center on your wheels at first but over time after landing big jumps having that much play will start wearing out surrending parts like the tiny pin that goes through you axle shaft before the hex will start ovalin out that hole which then in turn allows the hex to now have play causing the extension nut to use the play in the hex which will then start wearing out the hole in your wheels. I mean the list literally goes on the damge that having any play let alone that much play on any part for that matter will cause over time cause is absolutely insane!! An the fact is there's absolutely zero reason and I mean zero reasoning for them to even need to have any play!! The manufacture should be using the right size bit and drilling out the hex hole so the extension nut is just snugged enough when sliding in the hex!! It's pure lazyness on the manufacturer's part.An yes all of this damage did happen to me and all damages were paid for outta my pocket not the sellers or manufacturers so be warned strictly crawlers and light light bashing or speed runs ONLY!!! NO JUMPING OR ANYTHING LIKE THAT!!

These wheel extensions helped my Gen 7 from tipping while turning on hills, made truck a little more stable. A negative is my turning radius got bigger but my truck is still stock, gonna upgrade steering next. I think my truck looks little better with the wheels sticking out . Work great would def recommend

I ordered a set of the 20mm. Unfortunately, they are NOT 20mm. I didn't realize, until I got my good set of actual 20mm hex hubs and was able to compare size. So either the product is not as advertised, or I just received the wrong ones on accident. My new ones are from HR and are marked 20mm.

Outstanding...havent run yet but there isn't any play/slop. Im even using the stock pins 1.5mm, not new ones (1.9mm) that came with it.Only had to drill 3/16" hole in wheels to accommodate new wheel nuts. Easy/fastExactly what I wanted, but again, haven't run yet. Have the 15mm and 25mm versions, too.

Installed on my slash 1/16 4x4 fitment was pretty good. Just the little pins were too big for what I had which I expected… just took some old hood pins and cut it to size and working just perfect.

THESE DO NOT FIT A TRX4 , shaft size is larger than hole in these extensions. Will not fit in any way shape or form

the hubs on the 144001 are smaller than this! M3 not M4 If I get bored, I might try to install these on my B74!

Beautifully made
