A properly balanced engine is the key to performance and longevity. The all-new Fluidampr Balancer for the GEN5 Camaro LS3 / L99 is American made and built to last. The internal silicone technology continuously self-tunes in real time. This optimizes dampening the torsional vibrations at peak levels across a broad changing frequency range.
The Fluidampr Balancer is available in stock diameter and a 25% under drive. The under drive pulley does not affect air conditioning operation as it keeps the OE size pulley.
The installation is quite simple when using the proper tools. A special puller and installation tool are required for installation.
The first step is removing the serpentine belt. The small belt for the A/C does not use a tensioner. It is a stretch-to-fit belt. The easiest way to remove and install is to pull the belt toward the rear of the balancer and rotate the engine by hand. This will walk the belt off the pulley. Next, the center bolt is removed. This bolt should be discarded as they are designed to stretch and be used only one time. Install the puller and remove the balancer.
As you can see here, with the Fluidampr Balancer and the OE, there is a big difference in quality and design.
With the new balancer in place it is pressed onto the crankshaft with a GM Essential tool from kit J-43145.
Once the balancer is fully seated on the crankshaft a new bolt is installed. I chose to use a 12-point bolt from ARP. Coat the threads with ARP assembly lubricant then torque to 196 ft. lb.
Once the balancer is installed and torqued, the belts can be reinstalled. The A/C belt can be reused, but the serpentine belt will require a shorter belt. The instructions from Fluidampr include the proper belt part numbers. Once the belts are installed start the engine and verify proper belt alignment.
By installing a Fluidampr viscous damper you will reduce wear on the main bearings and timing components. This will increase efficiency through more accurate valvetrain operation and lower the risk of crank failure.
