Rivian R1S Splash Guards (Rear Pair) 2022–2026 — Low Profile ASA-GF, Minimalist Road Spray Protection

Low-profile rear splash guards for the Riv R1S that reduce bumper spray without the big mud flap look.
I wanted a minimalist rear splash guard for the R1S. Most options out there are huge and look like an add-on, so I designed a low-profile set that actually blends in.

The shape is intentionally angular (not the usual big curved “mud flap” look) but it still knocks down the light road spray that hits the lower rear bumper—especially after small puddles.

I ran these as material prototypes for 10,000+ miles of real driving and they held up flawlessly: no cracking, warping, or loosening.
