Description:

This bracket is meant to relocate the lower idler on LSA engines to allow for a larger diameter crank pulley on the blower drive. This bracket is intended to be used with factory bolts and factory idlers, but aftermarket idlers are also able to be used.

It is not recommended to use a 50mm idler pulley on the bottom though due to the likelihood of failure from exceeding the rpm limit of the bearings, hence why this bracket will be your best option when planning on running a bigger crank pulley!
