Exhaust leaks on your GM 3.8L V6 can lead to poor performance, excessive engine bay heat, and annoying ticking sounds. The Stage 8 Header Bolt Kit (5/16-18 x 7/8) is specifically designed to eliminate these issues by providing a secure, vibration-proof connection for your exhaust headers or manifolds. With their patented locking design, these bolts are guaranteed to stay tight, no matter how hard you drive.
The 3.8L V6 engine is a workhorse, but like many engines, it is susceptible to header bolts loosening over time due to thermal expansion. Standard bolts simply cannot handle the stress of high-performance driving. Stage 8 bolts feature a unique locking clip that prevents the bolt from ever backing out. This ensures a perfect seal between the header and the cylinder head, maximizing exhaust flow and preventing gasket failure. This kit includes 12 bolts, providing everything you need for a complete installation. Whether you are restoring a classic or building a performance machine, these locking header bolts are the ultimate insurance policy for your exhaust system. Find all your engine performance upgrades at GGCRACING.
