Coolant Bypass Kits
Whether you daily drive, routinely tow or have a high performance Cummins application, your rear cylinder suffers from excessive heat and pressure due to lack of coolant flow. Fleece Performance Engineering offers the tried-and-true solution for your automatic or manual trucks from 12V to current the 6.7 common rail engines. Coolant bypass kits feature OE+ fit and finish, braided lines and AN fittings for a clean, leak free installation.
