Product Details

The Quarter Master 509181 is a high-performance flexplate designed for Small Block Chevy (SBC) late model engines with no balance weight. This lightweight flexplate features a 153-tooth gear configuration, providing reliable engagement with modern high-torque starters and automatic transmission torque converters.

Key Features:

  • 153-tooth gear pattern for positive starter engagement
  • Designed for late model Small Block Chevy engines with neutral balance (no balance weight)
  • Lightweight construction reduces rotating mass for improved throttle response
  • Precision-machined for accurate bolt pattern alignment
  • Compatible with automatic transmissions requiring SBC bolt pattern
  • Manufactured by Quarter Master, a trusted name in racing and high-performance drivetrain components

This flexplate is engineered for engines that have been internally balanced or use a neutral balance configuration. It is not compatible with externally balanced engines that require a weighted flexplate. The lightweight design makes it ideal for racing applications and performance street builds where reducing rotational mass is a priority.

Thanks

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

I've had great service, quick shipment and awesome prices from Autoplicity. Definitely would recommend to anyone. I've placed multiple orders with them and everything is great!

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

all went smooth with check out now to see how fast the shipping concludes..

Best price I found and VERY fast shipping. Very happy.
