Product Details

The COMP Cams 4004 Spring Loaded Rocker Arm Stud Girdle is engineered to stabilize rocker arm geometry and prevent stud failure in high-performance Chevrolet small block engines. Designed for 265-400 cubic inch small blocks with 7/16" rocker studs, this girdle system distributes valve train loads across all studs rather than individual mounting points.

Key Features:

  • Spring-loaded design maintains consistent pressure while accommodating engine flex and thermal expansion
  • Compatible with Chevrolet small block 265, 283, 302, 305, 327, 350, 400 cubic inch engines
  • Works with 7/16" diameter rocker arm studs
  • Reduces stud flex and prevents stud pull-out under high valve spring pressures
  • Essential for aggressive camshaft profiles and high-RPM applications
  • Helps maintain proper rocker arm alignment throughout the RPM range

This stud girdle is particularly beneficial when running high-ratio rocker arms, heavy valve springs, or racing camshafts that create increased stress on individual studs. The spring-loaded design allows the girdle to maintain contact while compensating for dimensional changes during engine operation, making it superior to solid girdle designs in many applications.

Absolute best price on the web, very fast. Definitely ordering Autoplicity in the near future....

Hope it works

Bought Motive Brake Bleeding Kit (international) . Best Pricing all around.<br>Ordered on Tuesday , received via UPS Ground (cheap shipping) on Thursday Noon.<br>Excellent Packing.<br>Super Fast Shipping.<br>Very Statisfied with my on-line order.<br>Highly Recommended.

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