ICT BilletManual Belt Tensioner with Pulley Compatible with Corvette CTS-V G8 CTSV Z06 LS7 Aluminum LS1 LS2 LS3 LS6 Made in The USA 551617X-1

Great stuff from ICT. Easier to use than the stock spring loaded unit.

Attempted install on 04 c5 corvette with fluidampr balancer, no other changed along belt route. After an hour and change screwing with it I came to the conclusion it out right did not work.Worst things first:Pic 1- How belt should be with OEM spring type tensionerPics 2 and 3- How belt IS upon installing ICT billet tensioner. Resting on thermostat housing, clearly a no go.Aside from being utterly useless in my case, the main bracket also would not fit with the (specified for LS1 water pump) 0.19" aluminum spacers- although it did fit just fine with the 0.27". Obviously not the main issue however it is annoying to follow the instructions only to take the part off and redo.Finally, some points on this product as per ICT's site:"Replaces stock tensioner, allows you to add more tension to the belt than the stock tensioner, & allows for greater range of belt length fitment.""OEM length belt can be used""Compatible with Corvette, CTSV, water pumps (any year)"Perhaps I've misunderstood the application or the comparability of the product in which case I will delete this review- until then, I am baffled and sorely disappointed.

I have this on a 2004 GTO with an LSA blower. Fitment was great and a good quailty construction.
