Crower Titanium Retainer Set, For Nissan SR20
Crower titanium retainers are CNC machined in-house quality and batch to batch consistency. Crower titanium retainers are the perfect combination of strength and lightweight design and are specifically designed for stock valve springs. Weighing in at only 5.5-6.0 grams per retainer, they are nearly half the weight of a stock piece at 11.0-11.5 grams each. Remember, less weight means more RPM!
