    The Primary Tensioners are brand new. The latest design by MMR. These are a complete warranty replacement after I was sent a couple which were duds.

    The Chain Guides are almost new with only 20 miles on them. This is because the Tensioners I was sent were duds (I think I just got unlucky) and I had to go back in there and wasn't sure how the MMR Chain guides would interact with OEM Chain Tensioners so took them out.

    Was going to keep them until I have to rebuild but I'm only putting 4k to 5k miles a year on the car so thats like 15 years from now. Pretty sure I'm the only one in the UK to have had an issue as there are a fair few guys who have these parts and are doing well.

    I'm also throwing in OEM chains which were sent to me in error by Tasca parts and would cost me too much to send back.

    New Chain Guides on Nemesis are £450
    New Tensioner are £225
    Don't know how much new timing chains are in the UK.

    Pictures attached of the failed Primary Tensioner as well with the chain guides installed.

    575 pounds collected. Can ship at your expense. My loss, your gain. No offers please. They are a lifetime warranty part and they will go in to storage if not sold. 20200101_132308.jpg 20200101_132345.jpg 20200101_132227.jpg 20200101_132247.jpg 20200101_142029.jpg 20200101_132211.jpg 20200101_142419.jpg

    The MMR Chain Guides and Primary Tensioners are used by their World Record setting dragsters. The primary Tensioners are good for 11000RPM and up to 4000hp whilst the Chain Guides and Arms are rated for 10000plus RPM and 4000hp.

    Perfect for boosted application or if you are increasing the rev limit.

    Only reason not on the car is because I don't fancy going in there again right now to replace. Going in there a 3rd time just because I was sent duds is not fun but I will be going in there again at some point so hence I'm happy to keep
