    Better than the anchor

    If you have and 07 or early 08 and you have made the swap. You need to. It made a huge difference in how quickly and smooth the engine revs.

    Must have for 07 GT500's

    If you have a 2007 gt500 and you aren't planning on installing an OD crank pulley, then you need this! The 07 Shelby has a 23-26lbs harmonic balancer, which puts a lot of stress on the crank once you start adding performance parts, increasing the revs, or upgrading your blower. The weight saving is huge when you're talking about rotating mass. Install wasn't bad, took about 2 hours. Highly recommend for fellow 07 Gt500 owners.

    It is a must on 2007 GT500's

    A nice upgrade to do especially if you do any enhancements to your supercharger. It is a lot lighter than the stock balancer.
