Good price.
Easy install and working fine so far. Will need more time on it to give it an honest review.

Garbage- worst axle I’ve had
Garbage, failed with less than 20 miles on it. Only used in powder snow, manufacture won’t warranty it cause said it was abuse. lol. I’ve tried many other brands and this is by far the worst axle I’ve ever had. Definitely recommend buying any other brand unless you want to waste money like I unfortunately did. I had to give it 1 star but in reality I’d give it -5 star review

Great Product
Nice quality product - installs easily and fixes all your issues! ... Assuming they relate to your TRX420 having CV issues...

Much heavier axle
Ordered one for a grizzly 660, wanted a decent upgrade in durability, size, etc. So ordered this. Showed up real quick, 2 or 3 days, compared to stock grizzly axle this is about twice the diameter, super happy about that, appears to be a way stronger axle, by the looks of it the weak link now is the shaft into the diff rather than the axle itself, i dont think ill ever have trouble on this axle again, will be replacing all axles with one of these over time, adding a photo for comparison, as i had troubles finding a good comparison online between stock and this

Satisfied
Bought this and happy , most northerners order parts from a dealership and it gets
pricey for OEM parts so look to other sources to find guaranteed fit parts and
FortNine I’d say is the place to go. When we buy our off-road equipment it’s 99 percent of the time is hunting and fishing so quality parts is a must when parts are
hard to find sometimes.
