Cargo Rack / Dog Seat

"Since a stick came through my floorboard during a casual ride on a backcountry road, I refuse to drive my SxS without a skid plate. There is no reason to risk my vehicle or my family." - Gregg (UTV owner since 2005)

How to choose between HDPE and UHMW 
For most consumers, HDPE provides the best features for the price along with the most attractive material finish. 

Our HDPE has a matte black finish and our UHMW has a shinny finish.

UHMW can be up to 10x the molecular strand length as HDPE. This enables UHMW to be even more durable and abrasion resistant than HDPE. However, the unique manufacturing process that is needed to achieve UHMW’s performance leads to a higher material price and a less consistent color/texture.
