SplitFour 4BT Rocker Covers

SplitFour 4BT Rocker Covers – O-Ring Sealed, Hardware Included

EPC brings you the SplitFour — our exclusive 2-piece rocker cover system for the legendary 4BT Cummins.
While most options are either one big cover or four small ones, we’ve engineered the smarter middle ground: each cover shields two rockers, giving you the perfect blend of serviceability, sealing, and style.

Why SplitFour?

• Exclusive Design – The only 2-piece, dual-rocker cover system for the 4BT.

• Full Hardware Kit Included – Everything you need for easy install.

• Better Serviceability – Access just the section you need without removing it all.

• Built for Performance & Looks – Clean lines, CNC precision.

Kit Includes:

• 2 x CNC-machined rocker covers
