The oversized 8.8mm wire features a double silicone construction rated at over 600 F and 60kV. High gloss black silicone wire jacket not only looks great, but resists heat extremes, petrochemicals, ozone and moisture better than so-called blended materials for greater durability and longer life. High-density, high-temperature silicone insulation provides greater dielectric strength and eliminates arcing and the effects of corona better than typical OE style rubber materials. All-Kevlar stranded inner core and fiberglass braiding add greater pull strength and terminal retention. Stainless steel and brass terminals provide unsurpassed electrical conductivity and excellent corrosion resistance compared to terminals made of common or plated metals.

MSD Ignition – "MSD Ignition Crank Trigger Kit, Small Block Chevy, 6"" Balancer, 8600" (Part No.8600)

"MSD Ignition Crank Trigger Kit, Small Block Chevy, 6"" Balancer, 8600"

from

$519.99
For a long time, racers have known that one of the best things to do to an engine to improve performance is to stabilize the ignition timing. The MSD Flying Magnet Crank Trigger system does exactly that by using four magnets embedded in an aluminum wheel. Although similar in appearance to other crank triggers, the MSD Flying Magnet design works on a different principle. Most crank triggers have a wheel, with steel studs sticking out, bolted to the harmonic balancer. As the crankshaft turns, the studs pass by a stationary magnetic pick-up, triggering the ignition. This pick-up can be triggered by other bolts, debris, or even vibrations which will cause a loss of power or engine damage.
