Retainers are an integral part of your engine’s valvetrain. Strength and weight are the most important factors, and PAC’s lineup of 300 Series Chromoly, 400 Series Titanium, 500 Series Titanium, 600 Series Tool Steel, and 700 Series Tool Steel retainers provide many options for keeping your valve springs secure and your valvetrain happy up to redline!

Whether you’re making 4-second blasts down the 1/8 mile, hitting the chip at your local short track, blasting through the dirt in a Pro 4 truck, hammering the waves in an offshore boat, or lighting up the competition at a street light, PAC valve spring retainers always deliver.
