4L Model Range Obsolescence

Holset Turbos
4L Replacement Turbo

In November 2007, Cummins Turbo Technologies announced the intention to obsolete 4L product, due to:

  • Falling sales over the past 10 years
  • Increases in the cost of manufacturing low volume parts
  • 4L tooling reaching the end of its lifespan.

All turbochargers in the following model ranges and associated parts are now obsolete: 4LE, 4LEK, 4LEV, 4LF, 4LFK, 4LFV, 4LG, 4LGK, 4LGV, 4LGZ, 4LHR.

As mentioned in previous communications, this Technical Bulletin indicates suggested replacements.

Turbochargers from the original list that do not have a replacement are shown in red.

Replacement Turbochargers

  • Some new turbochargers replace the 4L’s without impact on installation so are ‘drop in’ replacements (others may need alterations to mating items)
  • Modern aerodynamic design offers fuel economy benefits, potentially reducing operating costs
  • Modern improved bearing design gives improved reliability and durability, offering longer turbo life
  • Due to current products being more cost effective to produce many replacement turbochargers will offer a price reduction
  • Current product has better availability thus reducing lead times; many will be ‘off the shelf’
  • Due to improved performance, one HX part number may replace several 4L’s, resulting in less stock held to support customers.
