Upgrade your 2016–2019 Nissan Titan XD 5.0L Cummins with the RCD Performance CPX Injection Pump — the redesigned and reinforced version of the Bosch CP4 that eliminates its common failure points. Featuring pinned lifter buckets, an updated feed port, and internal return-to-tank routing, the CPX pump prevents the catastrophic roller rotation and metal contamination that destroy injectors and high-pressure systems on the 5.0L Cummins.
The CPX pump remains a true drop-in replacement, requiring no additional fuel lines, fittings, or modifications. Engineered with precision 5-axis CNC machining and backed by a 24-month no-questions-asked warranty, this pump provides unmatched reliability and protection, even under low-pressure, gel, or filter-change events. Whether your Titan XD is stock or tuned, the CPX is the strongest and most dependable CP4-based pump available.
