SMF Kits

National Auto Parts has been suppling high-quality Single Mass Flywheel (SMF) clutch kits to the automotive aftermarket since 2007.

Prototyping 2005 - 2006

Billet flywheels made at NAP’s Nottingham facility. Extensive vehicle trials were carried out as proof of concept.

Mercedes Benz Sprinter 2.3D

VW Polo Mk4 1.9D

GM Frontera 2.3 TD

2007 launch

After the prototyping and proof period, the first two to launch were the Mk6 Transit 2.4 TD, and the VAG 1.9 TD.

Sales to date of these two kits have exceeded 115,000.

First to market

The ability to offer products that are new to the aftermarket is an important aspect of NAP’s development program, and is often customer led. All of these SMF clutch kits were introduced to the market first by the team here at National Auto Parts.
