COMP Cams 4017 Stud Girdle for Ford 429-460 with TFS Motorsport Heads 7/16" Studs

The COMP Cams 4017 Stud Girdle is engineered specifically for Ford 429-460 big block engines equipped with Trick Flow Specialties (TFS) Motorsport cylinder heads and 7/16" rocker arm studs. This precision-machined girdle provides critical rocker arm stability by tying all the rocker studs together into a single rigid structure, eliminating individual stud flex and preventing stud pull-out under high valve spring pressures.

Key Features:

• Application-specific design for Ford 429-460 engines with TFS Motorsport heads
• Compatible with 7/16" diameter rocker arm studs
• Reduces rocker arm geometry changes caused by stud flex
• Prevents stud pull-out in high-performance and racing applications
• Maintains consistent valve train geometry at high RPM
• Precision-machined for accurate fitment and optimal performance
• Essential upgrade for aggressive camshaft profiles and high valve spring pressures

Stud girdles are a critical component in high-performance valve train systems, especially when running aggressive camshaft profiles with heavy valve spring pressures exceeding 400 lbs. By distributing loads across all studs simultaneously, this girdle ensures consistent rocker arm geometry, reduces valve train wear, and helps prevent costly engine damage from stud failure. This is an essential upgrade for serious street/strip and racing applications running TFS Motorsport heads on Ford 429-460 big block engines.
