Product Details

The COMP Cams 750-1 is a precision-engineered steel valve spring retainer designed for high-performance engine builds. This retainer features a 10-degree Superlock design that provides superior valve spring retention and allows for increased valve lift without coil bind.

Key Features:

  • 10-degree Superlock design for enhanced valve spring stability
  • Fits 1.250" outside diameter valve springs
  • Constructed from high-strength steel for durability under extreme conditions
  • Precision machined to exacting tolerances for proper valve train geometry
  • Compatible with 7-degree locks (keepers) for secure installation
  • Ideal for racing and high-performance street applications

The 10-degree taper angle provides a wider contact area between the retainer and locks compared to conventional 7-degree retainers, reducing stress concentration and improving reliability in high-RPM applications. This retainer is engineered to work seamlessly with COMP Cams valve springs and is a critical component for building a reliable, high-performance valve train.

Great price and fast shipping! If your looking for quality brands at the best price available!!<br>

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Excellent service. Fast shipping and email confirmation.

Awesome experience

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!
