Product Details

The Dart 63121212 is a precision-engineered manganese bronze valve guide designed specifically for use with 11/32-inch diameter intake valves in Chevrolet big block engines. Manganese bronze construction provides excellent wear resistance and thermal conductivity, making it ideal for high-performance and racing applications where durability and consistent valve operation are critical.

Key Features:

  • Manganese bronze material for superior wear resistance and heat dissipation
  • Designed for 11/32-inch diameter intake valves
  • Application-specific for Chevrolet big block engines
  • Precision-machined for accurate valve stem clearance
  • Sold individually for easy replacement of worn guides

Valve guides are critical components that maintain proper valve alignment and control oil consumption. The manganese bronze alloy used in this guide offers an excellent balance of strength, machinability, and lubricity, extending valve train life while maintaining consistent performance. This guide is intended for intake valve positions only and should be installed by an experienced engine builder with proper tooling.

Wow, first time I ordered and they hit a homerun with me!! Shipped same day I ordered AND was the cheapest option I had including shipping. I'll be back. Thanks for the great service!!

Had just what I needed, discounted shipping, and was able to check out using Amazon.

Ok so far

Quick and easily linked to amazon for payment.

The item was what i was looking for and the price was right. Item was very good quality. Would order from Autoplicity again.

Fast

Great price! Can't wait to see how the rest of the transaction goes.

This was my first order with Autoplicity. Their prices were great, and the ordering process very easy. I was a little frustrated at first, as the order didn't arrive as expected. When I called, it took a little work, but I finally got the info that it was shipping from the manufacturer, and did get the tracking info. The parts arrived when tracking said it should. Would I place another order with Autoplicity? Short answer is yes!

Great Seller, This is my second order with Autoplicity. Both times, item was shipped with in 1 day. I received both items within 3 business days. I got a great price. About 30% lower price than anywhere else. I will be shopping here again.
