Review SPEED PRO Sealed Chrome Moly Valve Spring Retainer 1.550 Inch Od 1.125 Id fits 550 125

The PRO VSR-7005R-8 and VSR-7005R Moly Valve Spring Retainers are high-performance components designed for use in racing and high-performance applications. These retainer assemblies are engineered to provide superior clamping force and durability compared to OEM retainer assemblies.

The retainer body is machined from 6061-T6 aluminum and features a 1.550 outside diameter and a 1.125 inside diameter. The molybdenum coating on the inside surface of the retainer provides excellent lubricity and reduces friction between the retainer and the valve spring. This coating also helps to dissipate heat, allowing the valve train to operate more efficiently and at higher RPMs.

The retainers come with titanium detent balls and springs that provide a positive detent and excellent retention of the valve springs. The detent balls are held in place by a retaining clip, which is made of high-strength steel. The clip is designed to provide a secure fit while also allowing easy installation and removal.

The VSR-7005R-8 retainer is designed for use with valve springs that have a height of 0.700 inches or less, while the PRO VSR-7005R retainer is suitable for use with valve springs that have a height greater than 0.700 inches. Both retainers are designed to provide excellent sealing and to withstand the high loads and temperatures encountered in racing and high-performance applications.

In summary, the PRO VSR-7005R-8 and VSR-7005R Moly Valve Spring Retainers are high-performance components that provide superior clamping force, durability, and lubricity compared to OEM retainers. They are suitable for use in racing and high-performance applications and are designed to withstand the high loads and temperatures encountered in these environments.
