Chevrolet Big Block V8 External Balance Rattler Harmonic Balancer.

All internal combustion engines display crankshaft torsional vibration. As the piston rises and falls so does cylinder pressure. The changing pressure results in forces being transmitted along the connecting rod and applied to the crankshaft journal. The TCI Rattler counteracts those vibrations by using internal rollers that automatically offset twisting forces that cause vibration (see Fig. 1). The Rattler is an absorber that eliminates the root cause of torsional vibration. It is effective for the entire RPM range and extends crankshaft and bearing life, as well as increases valve train stability and life. The design does not utilize viscous fluids and requires virtually no maintenance. And the unit?s timing marks are etched onto the body and cannot move relative to crankshaft centerline. The Rattler is also lighter in weight than most units of the same size and material construction. Its design features steel rollers (centrifugal pendulums) that fit loosely into a specific number of holes. By using patented, exact mathematical relationship, the rollers will roll forward during compression stroke and backward during power stroke to keep engine speed variation and vibration to a minimum. The rollers actually store and release energy back into the crankshaft rather than converting it to heat energy as dampers do. Rattlers are not frequency specific but are based on the number of cylinders used in the engine or events per revolution so they are practical for street use, as well as oval track and drag strip use. CNC-machined to exacting tolerances

Title

Chevrolet Big Block V8 External Balance Rattler Harmonic Balancer.

This is my first time ordering from Autoplicity and there's a good reason part of simplicity is the name. I buy stuff online all the time an this website is definitly easy to navigate. The price was resonable and shipping turnaround was fast.

Quick & easy! Great pricing!!

Autoplicity had the cheapest price, I got my order in 3 business days, and let me know through email when they received my order, shipped my order, and completed my order. Was really impressed!

Very quick and easy.<br>I hope the installation goes the same way.

Excellent price, quick shipment, and recommended to anyone! They have the cheapest prices on the web! Period!

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Awesome price on a name brand part. Good communication too. Many payment plans and you can use your PayPal !!

I was searching for brake rotors on the Internet for over 3 hours tring to find the best prices-- Autoplicity beat everyone hands down! The best deals out there. Quick response and my order shipped within one business day! Bravo. <br><br>Their website could be improved by auto selecting make/model combinations. I had to double check the part numbers for the pads..they matched the rear pads with the front rotors. I only caught this due to the fact that the pads were extremely cheap..too cheap. The low price was for the rear set as front pads usually at more expensive due to their larger size.

I couldn't find this in stock anywhere! Not only did Autoplicity have it in stock they were about $10 cheaper than any other sites list price. Received the package very fast! Will use Autoplicity for all of my part needs!
