About this part

Product Details

This product includes a set of 16 Manley Performance titanium valve spring retainers, designed for LT4 engines. These retainers are made from special 6AL-4V titanium, a material chosen for its exceptional strength-to-weight ratio. They are CAD designed to reduce mass as much as possible without compromising the strength needed to control your valve springs under demanding conditions.

You'll need to use 7-degree valve locks with these retainers. Manley recommends their own P/N 13098 valve locks, but factory Chevrolet LT valve locks will also work. These retainers are dimensionally the same as Manley's steel retainers (P/N 23628) but offer the significant weight savings of titanium. Compared to Manley's P/N 23623, these offer an additional 0.055 inches of installed height, giving you more tuning flexibility for your valve spring setup. Each retainer weighs just 10.0 grams, contributing to reduced valvetrain mass.
