I ordered a set of black spline drive off amazon

I had these on my last truck too, no problems
I just got back from a weekend of sledding in the rockies, they were magnificent in the snow! and had to drive through a snowstorm on the way there, the tires were great, look great and arent loud, slight audible hum.
Thanks! The ride is no different than the factory offroad Rancho suspension, They are not cranked all the way up, but I still have 3" of lift. The only difference I feel is the stiffer 12 ply tire and shorter sidewall.
