Product Details

The COMP Cams 4018 Spring Loaded Stud Girdle is engineered specifically for Chevrolet small block engines equipped with Brodix cylinder heads and 7/16" rocker studs. This precision-machined girdle provides critical valvetrain stability by tying together the rocker arm studs, reducing flex and deflection under high-RPM operation.

Key Features:

  • Spring-loaded design maintains constant pressure on rocker studs to prevent loosening
  • Reduces stud deflection and improves valvetrain geometry consistency
  • Specifically designed for Brodix cylinder head stud spacing and 7/16" studs
  • CNC-machined from high-quality materials for precise fitment and durability
  • Helps prevent rocker arm stud pull-out in high-lift, high-RPM applications
  • Essential upgrade for performance and racing engines with aggressive cam profiles

This stud girdle is a critical component for serious performance builds, helping to maintain valvetrain stability and prevent costly engine damage from stud failure. The spring-loaded design ensures consistent clamping force throughout the engine's operating range, making it ideal for street/strip and racing applications running high valve spring pressures.

Awesome price! Shipping could be faster, but it was fast enough. Will deff buy again.

Good customer service.Very friendly persons in service dept as well. Will shop here again.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!
