Description
Performance Replacement Harmonic Balancer. Maintain your performance engine using this Engine Harmonic Balancer for your Jeep. This simple component reduces vibrations and noise from your performance engine. This part connects using stock bolts and delivers reduced vibrations once installed.

I got into Jeeps at an early age, as a child around 3-4 year of age my parts got me a power wheel Jeep and the rest was history. Growing up I always wanted a Jeep, from the day I started driving I spent my days behind the wheel of a Jeep branded vehicle, which has not changed.
