07-S-110 Hamilton Cams Competition Valve Springs - Dodge 5.9L/6.7L Cummins 1998.5-2018

The Hamilton Cams 07-T-001 1.45" Tappets are specially designed to fit all 1989-2018 Dodge 5.9L & 6.7L Diesel engines. At 1.45" they will not have interference with the Fuel pump eccentric on 12v engines and are much wider than the 1.1" tappets used in early 12v engines. This means they have more surface area to work with wider lobes which will promote much better lobe life with today's low zinc oils.

Increase performance in the valvetrain of your 1998.5-2018 Dodge 5.9L / 6.7L Diesel with the Hamilton Cams 07-S-003 Valve Springs. Stock 24v springs have 78-82lbs of seat pressure at 1.380″. If you are over 35psi (boost or drive pressure), stock springs do not fully control the valvetrain. Intake and exhaust valves can be blown open by boost and exhaust drive pressure which allows reversion.

The Hamilton Cams 07-P-004 Extreme Duty Pushrods from XDP are a must-have if you are making over 500hp in your 1998.5-2018 Dodge 5.9L/6.7L Diesel. The cylinder pressures acting on the valve can bend the OEM pushrods before the valve opens. This can retard cam timing and reduce valve lift.
