The Powermax R1 Rotor Arm is the perfect upgrade for your Lucas 23D or 25D Distributor 4 Cylinder.
This rotor arm replaces original Lucas part numbers GRA2101 or DRB101C. It's an improved version over the original.
Fitted to British classic cars from the 1950s, 60s and 70s, the Lucas 23D4 and 25D4 is one of the most widely used distributors we've ever come across! If you've got a Mini, Allegro, Sprite, Cortina, MGA, MGB, Magnette, Midget, Marina, Minor, Series Land Rover, Avenger, Herald, Toledo or Wolseley, then this rotor arm is for you. If you're unsure about fitment, please contact us. The list of vehicles that this rotor arm fits is beyond extensive.
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.

This is my second rotor arm and the first I still carry as a spare. They are good quality and long lasting.
