Why Upgrade to ARP Header Studs?
Because header bolts backing out mid-drive is not a personality trait—it’s a problem.
Unlike standard bolts, studs provide more consistent clamping force, reduce thread wear in the cylinder head, and make installation easier (especially when you’re juggling headers in a tight engine bay).
Key Features
- Premium Stainless Steel Construction
Corrosion-resistant and built to survive extreme exhaust heat cycles. - 12-Point Nuts Included
Easier access in tight spaces with better torque control than standard hex nuts. - Stronger, More Consistent Clamping
Reduces the risk of exhaust leaks and warped flanges. - Precision Rolled Threads
Ensures smooth installation and accurate torque application. - Reusable & Durable
Designed for long-term performance in high-heat environments.
