    Difference Between LET & LEH Crank

    What is the difference between the LET & the LEH crank?

    Is there any physical differences? Do they weigh the same?

    My plan is to send one off to get hardened and knife edged

    Thanks
    Lee

    LET one is harder and has the balancer shaft cogs

    LEH one is softer and doesn't have the balancer shaft cogs.


    Not sure about weight but I wouldnt be fitting a LEL or LEH one if your going for big power.

    Just not as hard as the LET one from what I found out with my own LEL crank and Regal told me they are softer.

    Lee it will still make a difference.. This isn't the same as a remap to a Stage 1 with set figures etc. From what I understand, the LET crank is a harder wearing crank than the LEH.. If you strengthen an already hard object you will benefit more than strengthening a softer object, even if they both go through the same process..

    lee im running both cranks in the cars.
    iv been running the zaf this year with the leh engine iv had it harden and balance the same way as the let crank and its seen to be ok. iv just striped the engine and looked at the crank and ther is no wear in it. im putting it back together wwith new bearings.
    i will be still running the leh crank with my new setup and it sould be ok.

    on the plus side the leh crank is lighter then the let crank and if u have it harden i doubt that it makes any difference.
