We love the fact that COMP Cams is in the problem solving business and that the keep solving them with a level of frequency that neither we nor the rest of the industry can keep up with! This time we are back with more good news for Gen III hemi owners. The 6.4L version of the modern Chrysler V8 has had a well known problem with lifters failing over the course of time. Obviously when a lifter goes, it typically is not a singular event. No, those lifters will wreck camshafts, send back stuff into your oiling system and generally ruin your day.
You have two options. Wake up and pray to the automotive Gods that your engine makes it another 24 hours and has no problems or you can seize control of the situation and upgrade your engine (along with its performance) with this set of link bar, short travel hydraulic rollers that are designed to keep your romping, stomping Chrysler engine from becoming a clanking and banking Chrysler engine.
COMP does it again and the full story is below.
COMP Cams® Expands Link Bar Short Travel Hydraulic Roller Lifters To Include Dodge 6.4L HEMI Applications
Memphis, TN – Install the COMP Cams® Short Travel Hydraulic Roller Lifters for Dodge 6.4L HEMIs and say goodbye to factory lifter failure.
Certain engines respond better to a light lifter pre-load because it recovers more quickly from any bad harmonics in the valve train. Others work better with a heavy pre-load because oil volume is reduced under the plunger, which increases lifter stiffness. COMP Cams® Short Travel Hydraulic Roller Lifters let you have the advantages of both light pre-load and reduced oil volume, producing the most stable and highest-revving hydraulic lifter available. In addition to excellent dynamic performance, all Short Travel Lifters feature a premium billet steel pushrod seat, which adds strength and durability in racing use.
Available now are two performance link bar lifter options for Dodge 6.4L HEMI applications; retro-fit link bar and upgraded XD versions. The XD lifters feature a REM polished finish for reduced friction and lifter bore wear, perfect for any extreme duty application such as high rpm track cars, supercharged engines and offshore powerboats.
