Secure More Than Just Headers with Stage 8 Fasteners from Summit Racing

  • thumbnail

Secure valve covers, flywheels, harmonic dampers, and more with these patented locking fasteners.

Why They’re Cool: Stage 8 made its name with locking header bolts. But the company makes fasteners for many other components too—even parts you probably never though needed the security of a locking fastener.

All Stage 8 locking fasteners use a patented system that consists of a grooved hex-head bolt, a retainer, and a snap clip. The retainer fits over the bolt head and locks the bolt against the component, and the snap clip holds the retainer in place. Once Stage 8 fasteners are tightened down, they won't back out.

Summit Racing offers Stage 8 Locking Fasteners for the following components:
• Headers, header collectors, and exhaust manifolds
• Valve covers
• Intake manifolds
• Oil and transmission pans
• Harmonic dampers
• Flywheels and flexplates
• Water pumps and starters
• Distributor hold-down clamps

Summit Racing also carries Stage 8’s X-Lock locking spindle nut kits for Dana 44 and Dana 60 axle (shown in photo). Developed for off-road racing vehicles, the X-Locks replace the OEM jam nut system. Laser-cut from heat-treated and through-hardened 4130 steel that has been heat-treated and through-hardened, the locks can be installed without any special tools. The spindle nut itself can be set to a specific pre-load value, and can be locked within a half-degree of any position so you will never over- or under-torque it.
