Why Choose the Genuine “Distributor Doctor” 54401050 Rotor Arm?
The Distributor Doctor is a well-respected name in the automotive world, particularly among enthusiasts of classic and vintage vehicles. Founded by Martin Jay, the company has earned a reputation for providing high-quality ignition components, particularly for older cars that require specific and reliable parts to maintain their performance and originality.
This rotor arm isn’t just any aftermarket part; it’s a genuine “Distributor Doctor” product, carefully crafted to match original equipment (OE) specifications. Here’s what makes this rotor arm stand out:
- Perfect for Specific V8 Models: The 54401050 rotor arm is designed for certain V8 models of Land Rover, Range Rover, Aston Martin, TVR, Rolls Royce, Bentley, Triumph Stag, Rover P6, and others that use the UK Lucas 35DE8 and 35DLM8 electronic distributors. This specific design ensures optimal performance for your classic engine.
- Cheaper than Flying Spares: If you are looking at a Rolls Royce or Bentley CD6077PP or CD6077 on Flying Spares, this is the same rotor arm – but much cheaper! (And if you want to know how to test the rotor arm on a Rolls or Bentley, read >this<)
- High-Quality Construction: Manufactured in the UK from USA-sourced Thermoset Polyester, the same material used by General Motors for their rotors, this rotor arm offers excellent heat resistance and durability. It’s designed to withstand high-performance applications, making it ideal even for TVR track cars.
- OE Specification Design: Crafted to exact OE specifications, the rotor arm guarantees a precise fit and function, ensuring your V8 engine runs smoothly and efficiently.
- Enhanced Performance: The rotor arm features an integrally moulded brass inlay, eliminating the risk of short circuits that can occur with cheaper riveted versions. Its enhanced insulation properties make it suitable for use with high-voltage coils and electronic ignition systems, ensuring consistent and reliable operation.
- Secure Fitment: The spring steel clip on the underside, combined with improved internal tolerances, ensures a secure and snug fit, even on older, slightly worn distributor shafts.
Important Fitment Information
Be aware that the 54401050 rotor arm is the slimmer version with no under-hang at the back. This design is essential for proper fitment in certain applications. If your vehicle’s distributor originally used the wider cheese slice 54422044 rotor (which has an under-hang), this rotor might not fit correctly. The 54401050 is specifically intended for use with later electronic distributors where the rotor height has been slightly reduced. This rotor is not suitable for cars with points.
Where to Buy the Genuine 54401050 Rotor Arm
