Proform Self-Locking Wedge Header Bolts

Proform self-locking wedge header bolts get a grip on your headers that won't let go—until you're ready! These permanently assembled bolt sets feature special washers with super-hardened serrated teeth that, when torqued to 28 lbs.-ft., bite into and grab the bottom of the bolt head and the top surface of the header. Any bolt-loosening rotation is blocked by the wedge-locking action created by the washers' interfacing cams; but what's really impressive is that engine vibration—the enemy—increases the tension, making them even more secure! The bolts are re-useable and you can count on them to not fail. Proform self-locking wedge header bolts put an end to the constant tightening for a leak-free, headache-free future. They're available in different finishes and sizes for applications from 1965 and up.

Mr. Gasket Header Bolts

Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.

Summit Racing™ Split Lock Bolt Kits

Summit Racing™ split lock bolt kits put a new twist on the theory of mechanical locking fasteners. These innovative bolts use a locking set pin built into the bolt itself—and when tightened, the set pin expands the bolt threads against the thread wall. This, in turn, provides a locking system without having to use any additional wires, locking compounds, or lock washers. To remove the split lock bolts, simply loosen the set pin and back out the fastener. They are available in a variety of thread sizes, for engine applications from the 1950s and up.

Sikky Manufacturing LSX Header Gasket Sets

Sikky Manufacturing LSX header gasket sets are high performance seals for GM LS engine swaps. They feature multi-layer metal gaskets and all necessary bolts, designed to create a durable seal for aftermarket headers in demanding, high-horsepower applications. These gaskets use stainless steel layers and embossments to withstand extreme exhaust pressures, preventing leaks during rigorous use in swapped vehicles. Additional details: * Includes two gaskets (one for each side) and all 12 bolts needed for installation * Multi-layer steel (MLS) for superior heat and pressure resistance * Made specifically for LS-based engines (LS1, LS2, LS3, etc.) in vehicle swaps, often paired with Sikky's swap components * Stress-formed layers act as springs to maintain a tight seal under extreme conditions * When swapping a powerful GM LS engine into another vehicle (like a BMW or older GM), standard gaskets often fail due to increased exhaust heat and pressure. Sikky's gaskets provide a robust, reliable seal, ensuring performance and longevity in these custom setups.
