Advance Spring Set, Distributor, Pertronix

Billet Distributor Mechanical-Advance Spring Kit by PerTronix®

Selectable spring tensions allow the advance rate to match the engine combination.

This PerTronix® kit changes the mechanical-advance curve in a compatible Flame-Thrower billet distributor. Three pairs of springs provide light, medium and heavy tensions for different rates of advance as engine speed rises. The kit also includes advance limiters. Choose and verify the resulting curve with a timing light; the kit does not replace the distributor's electronic module or vacuum canister.
