Product Description
The Powermax R20 Rotor Arm is the perfect upgrade for your Rolls Royce and Daimler V8 Distributor.
This rotor arm replaces original part number 425620 as used in Rolls Royce and Daimler cars from the late 1950s to mid 1970s. This V8 engine used the Lucas 20D8 distributor.
These cars include the ever popular Daimler Dart / SP250 and Rolls Royce Phantom and Silver Shadow series. There is a list of compatible vehicles further down the page.
Traditional rotor arms feature a moulded body with a metal conductor riveted to the body. Over time this rivet can come loose, so we developed the Powermax moulded rotor arm. Instead of a fragile rivet, the conductor and body are moulded together. This gives better strength and much more durability.
A rotor arm that utilises Powermax Technology will give better performance and more reliable, accurate spark control at high rpm.
Essential for the discerning enthusiast who understands the shortcomings of the old fashioned ignition technology.
