can anyone help?

[SKOAL400_311]

ok i saw a fourwheeler today that had the back plastic peices over the rim the so mud would not get clogged in them, i am not for sure of the technical name but it was the same color as the bike and it looked really sweet
anyone know where i can get some of these?

thanks for helpin

nac's racing sells some. they are for beadlock and race wheels. they are called mud plugs or sumpthin like that.

yeah they seem like they're a good idea, but I saw a guy with clear ones and dirt was just trapped between the cap and the wheel, made it seem kinda pointless to me, plus dirt can still get stuck on the inside of the rims
