Why HDPE Over Aluminum?

High-Density Polyethylene (HDPE) flexes on impact rather than denting or cracking, making it the smarter material choice for off-road doors. It's lighter to handle, won't corrode, and the textured surface holds up to UV exposure and trail abuse far longer than painted aluminum.

Fitment

Designed and tested to fit: Can-Am Defender Max HD9 (all model years). Direct bolt-on — no drilling or modification required.
