Fastline Group was formed in 1995 and operates from conveniently located premises in Riley Road on Kettering’s Telford Way Industrial Estate.

The company is still a family owned business and prides itself in delivering value and offering a great service to all of its customers.

With major brand partners such as Bosch, Delphi, Stanadyne and Denso, our staff with a combined experience of over 300 years are confident that we can advise on and supply the correct part for your application or vehicle. We have a very comprehensive range of Diesel injector pumps, injectors, truck parts and accessories in stock. Our portfolio of services also includes the repair of alternators and starters and the reconditioning of automotive radiators.

Northampton Diesel joined the Bosch Diesel Centre network in 2005 and demands that staff are extremely highly skilled. This is demonstrated by two staff having trained to Stage 3 Diesel Master Technician level. This qualification takes years of experience and study to complete and ensures that we deliver the best expertise in diesel.

One of the emerging technologies is ECU re-mapping which gives your vehicle more power and greater economy. Most vehicles can be re-mapped through the diagnostic port, but where this is not possible, we can re-map directly to the chip. As a Quantum Authorised Dealer, we are able to provide a national service delivered by local experts. Click here to go straight to our Quantum page.

Serving customers both nationally and internationally, we are large enough to deliver on service and quality but small enough to care.

We aim to provide at least one daily delivery and collection service to most of our regional account customers using our fleet of satellite tracked vans. Our system will allow us to save time and fuel by directing our nearest vehicle straight to you.

For national and international customers or customers outside our delivery area, we can offer overnight delivery and collection via carrier.
