San Rafael, CA: Most performance enthusiasts know Stage 8 Locking Fasteners. Their zero-failure locking systems are so trusted, Kooks Headers and Exhaust now includes them in their exhaust systems.

But Stage 8 makes locking systems for much more than header and turbo applications.

An often overlooked part of an engine is the harmonic balancer. When the outer ring of a harmonic balancer slips from its normal position, a vibration results. This vibration may cause the fastener on the harmonic balancer to come loose and cause costly crankshaft damage.

Stage 8 Locking harmonic balancer bolts are easy to use and are real assurance against harmonic balancer failure due to loosening fasteners.

The unique and functional design is just four pieces: a grooved bolt (grade 8 steel), a retaining washer, a locking retainer and a snap ring.

Stage 8 harmonic balancer bolt kits are available for most engines. For more information go to http://stage8.com/perfauto.html and search by platform or call 415-485-5340.

For 31 years, Stage 8 Locking Fasteners has built the world’s best locking fasteners in a myriad of industries including automotive, industrial, railroad and military. Since 1985, Stage 8 has consistently delivered measurable increases in equipment reliability and safety as well as dramatic reductions in maintenance costs and equipment failures, especially header, exhaust and turbo applications.
