RPM 4-Stage Catch Can 5.5oz High Capacity Bottom Tank

RPM SxS 4-Stage Catch Can 5.5oz Extended Capacity Bottom Tank

Spend more time on the trail and less time draining your catch can with the RPM SXS 5.5oz Extended Capacity Bottom Reservoir Tank! Designed specifically as a modular lower reservoir upgrade for the RPM 4-Stage Billet Catch Can, this extended billet reservoir increases fluid volume to handle high-mileage runs, long-distance desert excursions, and high-boost applications with elevated blow-by.

Aggressive riding, elevated boost levels, and multi-day overland adventures fill standard catch can reservoirs quickly. This extended lower tank adds substantial holding volume for separated oil vapor, fuel dilution, and condensation—significantly extending maintenance intervals without altering the sleek lines or chassis placement of your catch can.

Constructed from CNC-machined billet aluminum and hard-anodized for chemical and corrosion resistance, installation is a straightforward 100% bolt-on swap. Simply unbolt your standard lower cup, swap the Viton O-ring, and bolt the extended reservoir directly in place using the included stainless hardware. For clean, mess-free servicing, each tank includes our precision easy-turn, dual-seal mechanical drain valve.
