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.

Stage 8 Locking Header Fastener Kits

Stage 8's Grade 8 locking header fasteners use a patented system that consists of a grooved hex-head bolt or nut, a retainer, and a snap clip. The retainer fits over the bolt head and locks the bolt against the header tube, and the snap clip holds the retainer in place. Once Stage 8 header fasteners are tightened down, they won't back out, eliminating leakage and blown header gaskets from loose bolts.

EMPI Heater Box Delete J Tubes

For vehicles with rusted-out or missing heater boxes where the owner has no need for cabin heat, EMPI's heater box delete J-tubes is a relatively inexpensive alternative to purchasing new heater boxes. The J-tubes directly replace the factory heater boxes, which are no longer functional. These components offer benefits primarily for performance-oriented or custom builds where the stock heating system is not needed, focusing on weight savings and improved accessibility to other engine components, such as the valve covers, starter, clutch adjustments, and fuel lines, making maintenance and adjustments easier. The EMPI J-tubes are manufactured from high-quality tubing, with a thick flange that is TIG-welded for a proper seal. The J-tubes come with gaskets and are designed to fit the upright Type 1 and 2 engines. Sold as a set of two.

Yoshimura muffler repack kits are available for well over a hundred varieties of Honda, Kawasaki, Suzuki, Yamaha, KTM, Polaris, Can-Am, and BMW mufflers.
