2007-2014 Shelby GT500 Auxiliary idler/tensioner


Available for both your OEM intercooler adapter and your J2Fab -16AN intercooler adapter.

This auxiliary idler is the only idler on the market that allows you to get the benefit from both the J2Fab A2W system and an extra idler pulley to increase belt wrap.

Machined in house from USA Made 6061-T6 aluminum, you can rest assured you are getting the highest quality critical components for your Shelby.

In addition to being compatible with the J2Fab flow mod, this unit also incorporates a fully rollerized adjustable manual tensioner.

The tensioner is not meant to replace your OEM location spring tensioner, rather supplement it to find the perfect amount of tension as well as make pulley/boost changes at the track on the fly without having to carry an arsenal of belts!

Only select yes for flow mod revision if you are using the J2Fab flow mod.

Fits most popular superchargers for the GT500 such as – Whipple 2.9, 3.0, 3.8 and TVS2300.

May fit other units without or with modifications
