Product Details

The COMP Cams 731-1 is a high-performance titanium valve spring retainer designed for serious engine builders who demand maximum durability and reduced valve train weight. Precision-machined from lightweight titanium alloy, this retainer offers exceptional strength-to-weight ratio compared to steel retainers, allowing for higher engine RPM and reduced valve train inertia.

Key Specifications:

  • Material: Titanium alloy construction for maximum strength and minimum weight
  • Angle: 10 degree taper for proper valve spring engagement
  • Spring Compatibility: Designed for double valve springs with 1.500" to 1.550" outside diameter
  • Application: High-performance racing and street performance engines
  • Weight Savings: Significantly lighter than steel retainers to reduce valve train mass

Performance Benefits:

  • Reduces reciprocating mass for improved high-RPM valve train stability
  • Allows for more aggressive camshaft profiles and higher rev limits
  • Exceptional durability even under extreme racing conditions
  • Precision-machined for accurate fitment and consistent valve spring load
  • 10 degree angle matches COMP Cams valve springs and performance valve train components

This titanium retainer is an essential upgrade for any high-performance engine build where valve train weight reduction and reliability are critical. Compatible with COMP Cams valve springs and most aftermarket performance valve train systems using 10 degree retainers and double springs in the 1.500"-1.550" OD range.

Just what you want from a merchant but don't expect; fast, courteous service and attention to the details of your order. I'm a happy consumer. Thank you, Autoplicity. I'll be back.

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.
