2007-2014 Shelby GT500 Idler Kit with 2.60 Supercharger Pulley

 

JDM combines the 2.60 upper pulley Kit and the Auxiliary Idler Pulley Kit together for a significant price discount for your 2005-2014 Shebly GT500. The 2.60 upper pulley will add approximately 4 more pounds of boost to the factory supercharger. This will increase the power out put approximately 40 RWHP.

In place of a shorter belt JDM uses an auxiliary idler pulley to increase belt tension to mazimize belt wrap and eliminate belt slippage. This pulley has 3 different setting positions to take up the correct amount of belt slack depending on the size of your supercharger pulley. Installation time takes less than 2 hours.

This kit consists of a heavy-duty, machined aluminum plate and the idler pulley is a 90mm double-bearing idler pulley. No modifications to the vehicle are necessary.  

Additional pulleys can be purchased, see our GT500 section for more options.

A custom tune is suggested with the use of this pulley. See our section for custom tuning.

Spark plugs are also suggested when adding boost to your vehicle. We recommend using NGK TR6 which can be found on our site ungapped, but we do suggest a .030 gap plug.

A pulley removal tool in necessary for removing the stock pulley. Pulley Tool can be found on our site also.
