Thread: Timing chain gear ?

  1. Default Timing chain gear ?

    What's best one to use ? Hex adjust sounds handy for fine tuning.

    But for example with these two...what's the difference ?

    CLOYES HEX ADJUST RACE BILLET C5R TIMING HD TIMING CHAIN SET LS2
    3 BOLT CAM 4X

    CLY9-3672TX3Z

    I'm totally flexible as to any timing setup that will work on an LS2 block with 3 bolt camshaft. Trigger type is unimportant

    I'm using the GT9 camshaft and Patriot Extreme springs on TFS 225cc cathedral heads with 1.7 YT Ultralights
    And will be using approx 7k rpm ( seemed quite happy to rev to this last time out )
    Previously I had a duplex Rollmaster setup, although could just re-use it. But I'm fitting a Melling HV pump so this may create clearance hassles.

    The 9-3172AZ is the Hex Adjust style sprocket with the single row true roller C5R timing chain for the LS2 3 bolt cam 4x reluctor.

    The 9-3672TX3Z is the Race Billet 3 keyway style sprocket with the single row true roller C5R timing chain for the LS2 3 bolt cam 4x reluctor.

    So the item description for the TX3Z is incorrect ? or is it also a Hex adjust too ?

    Also the title and description of this one suggest it has the C5R chain...yet the part listing says it's a premium roller ?

    Default Cloyes Timing Chain Questions LS Extreame Duty C5R Chain

    The 9-3172A is the single row Premium True Roller chain.
    The 9-3172AZ is the Extreme Duty C5R chain
    The 9-3172TX3Z is the Extreme Duty C5R chain

    The TX3Z is not a Hex Adjust style but a 3 keyway sprocket.
