Product Description

Upgrade your S&S CP4 Disaster Prevention Kit to the latest Gen2.1 spec with the genuine S&S Fuel Return Filter Assembly (RFA). This billet return filter head assembly modernizes the original “Gen2” bypass setup with improved debris isolation and OE-style quick-connect lines for a clean, reliable install.

Is this the right upgrade if I already have an S&S Gen2 CP4 bypass kit?
Yes. The Gen2.1 Return Filter Assembly is designed as a direct upgrade path for trucks equipped with the earlier S&S Gen2 bypass kit, using the same quick-connects and mounting footprint for an easy retrofit.
Does this include everything to add the bypass system from scratch?
No. This RFA is the return filter assembly upgrade component. For trucks without an S&S Disaster Prevention/Bypass Kit installed, you’ll want the complete Gen2.1 kit for your 6.7L.
What years does the Gen2.1 coverage include?
S&S states one part number covers 2011+ 6.7L Powerstroke applications with Gen2.1. Our product name targets 2011–2024 to match CPP’s cataloging; confirm your exact build date before ordering.
Why upgrade to the Gen2.1 return filter head?
Gen2.1 improves debris management on the return side and maintains OE-style serviceability with a standard spin-on filter, helping protect downstream components when CP4 issues occur.
Always verify contents and fitment against your VIN before purchase and installation.
