Rotor Arm, 25D4, high quality

Regular Price: £8.00

Special Price £6.00

In Stock

Cheaper rotor arms available are prone to failing prematurely as the material is too conductive, the rivet which holds the brass inlay into the moulding is slightly longer than the original, bringing it too close to the spring clip on the underside. As a result the high tension current, averaging 30,000 volts, shorts out from the tip of the overlength rivet, through the reduced thickness of more conductive plastic via the spring clip on the underside of the rotor arm to earth out down the distributor shaft. Result - no sparks at the plugs. These Distributor Doctor rotor arms are modelled on the original, dependable 1960's design, but made from modern materials on the latest machinery to very close tolerances. These arms will not let you down. The integrally moulded brass inlay dispenses with the troublesome rivet used on most versions which is known to short circuit. The increased insulation properties of the body makes them suitable for use with high voltage coils & electronic ignition kits. The spring steel clip on the underside, in conjunction with a revised internal tolerance assures a really snug fit, even on old & slightly reduced diameter mountings.
