Quality in Kilen Coil Springs

Kilen explains the measures taken to ensure the quality of their market renowned coil springs.

With one of the industry’s most extensive ranges of coil springs, Kilen has introduced more than 190 references through FPS over the past 12 months.

Highlights include:

  • 12230(A) for Fiat Punto 1.4 (2012-2015)
  • 50237(A) for Audi A3 1.6 (2003-2013)
  • 11132(B) for BMW X5 xDrive 3.0 (2010-2014)

Produced in their own factories to ensure high quality standards and full control over availability, Kilen offers both parallel wire (constant thickness) and tapered wire coil spring designs to offer more choices to the installer.


Kilen springs use only the highest grade steel from selected mills to achieve the exceptional surface and internal wire quality that is necessary for modern suspension springs to ensure safety of their springs. This reduces their susceptibility to surface and inner defects. These defects impede spring fatigue strength that leads to premature sagging and increase the risk of early breakage.

After coiling, each Kilen spring undergoes a multi-stage heat treatment process to improve fatigue strength while ensuring a tough and ductile spring. The springs are then bombarded with millions of tiny steel shots in a process called ‘shot peening’ to further improve fatigue strength and provide an optimal surface for painting.

Kilen protects each spring from corrosion with a chemical process known as zinc phosphating and coats them with an epoxy powder resin which is much more durable than standard paint.


Firmly committed to providing the highest quality products, Kilen springs are manufactured in compliance to BER330 and 461. Guaranteed to match or exceed OE quality, Kilen springs can be fitted without any warranty restrictions.

Kilen coil springs are supplied with a comprehensive warranty – three years on parallel springs, and two years on tapered wire alternatives. Catalogued on the F:Drive and MAM Autocat, Kilen springs are available from FPS via same/next-day delivery. For more information, please speak with your local FPS representative.
