This tensioner bracket bolts onto all Vette offset OEM or aftermarket water pump, and allows the use of the popular Cummins 6BT style belt tensioner, commonly sold under the Gates 38518 part number (sold separately). This bracket fits all C5/C6, V1, G8 and LSA accessory drive water pumps (LSA water pump only if you are running a single belt, wont clear dual belt tensioner setups). There are 10 clock-able indexing holes for tensioner body clocking to get the ideal geometry and tension on the belt. Kit comes with bracket, 3 billet spacers, and hardware to bolt the tensioner to the bracket. The stock tensioner hardware holds the bracket to the water pump, and there is a third bolt that goes back to the head for the most rigid setup on the market.
We do also offer a tensioner idler pulley "body" with shoulders on the sides that can replace the stock steel non-shouldered pulley as an upgrade if needed. You must press out the existing bearing and press it into the new billet idler pulley body, or purchase a NEW bearing at the link below. The offset of this tensioner will work with both OEM 6 rib and all 8 rib setups that add 2 ribs forward. If you are running in 6 ribs, you will use the REAR 6 ribs on the tensioner, the same as if you are using one of our Vette offset LSA or LS9 blower pulleys.
If you wish to buy a NEW bearing for the tensioner idler pulley instead of pressing out the old one if you are using one of our high shoulder pulley options, the bearing can be purchased from Amazon at the link below:
The 2 part numbers that will work are 30BD40 and 5106WCC

Brackets will come in standard black and clear anodize, but custom colors are available, just select that option in the drop down menu and add a note at checkout. Spacers are not normally anodized but can be done as a custom request as well. Most orders will come with the idler pulley (if selected) in BLACK only, unless otherwise specified at checkout.
