Product Details

The COMP Cams 748-1 Superlock steel valve spring retainer is engineered for high-performance engines requiring precise valve train control. Designed with a 10-degree locking angle, this retainer provides superior lock engagement and reduces the risk of keeper failure under high-RPM operation.

Key Features:

  • 10-degree Superlock design for enhanced keeper retention
  • Fits valve springs with 1.500" to 1.550" outside diameter
  • Precision-machined steel construction for durability
  • Ideal for racing and performance street applications
  • Compatible with 10-degree locks/keepers (sold separately)

This retainer is a critical component in high-performance valve train assemblies, ensuring reliable valve spring control during aggressive cam profiles and elevated engine speeds. The steel construction provides excellent wear resistance while maintaining lightweight characteristics essential for reduced valve train mass.

Awesome job guys! communication was super fast! price was cheap and shipping fast! definately do buisiness with these guys again

Great

This is my 4th autoplicity purchase. I love you guys!!

So far, very easy. Price, Delivery Time and Quality were very Good. Thank You.

We ordered a Thule 9003 Raceway 2-bike rack for my 2011 Honda Civic and it arrived in 2 days. We were very surprised at the fast service. I also had my thoughts that it wouldn't be the exact name brand product I was looking for and a off brand but the same type and I have to say it was exactly the product I wanted. The price was great too. I researched several dealers and Autoplicity was the lowest price at $100 less than others and that included the shipping. I would definitely order from Autoplicity again.

I'm a new customer to Autoplicity and I just bought a Thule Bicycle Rack for a great price!! Autoplicity had a great price that didn't even compare to other websites prices. The shipping is super fast and it was in great packaging and shape when I received the bike rack. Thanks and I will definitely shop at Autoplicity again! Highly recommend!!

I like your prices on parts and ease of navigating on your site.

Thanks

Easy to find and to pay with amazon.

So far so good

Quick and straight forward. Good Job!

Quick, cheap & dirty!

Great customer service and communication. Would buy again and again. Thanks a lot
