Product Details

The MICHIGAN 77 MS2321HX is a high-performance H-Series main bearing set engineered specifically for Dart LS Next engine blocks. This complete bearing kit features extra oil clearance design, making it ideal for high-performance and racing applications where increased oil flow is critical for engine protection.

Key Features:

  • H-Series construction designed for NASCAR-type racing and high-performance applications
  • Extra oil clearance (HX designation) provides enhanced oil flow for demanding conditions
  • Standard size bearing set for Dart LS-Series aftermarket blocks
  • Premium tri-metal construction ensures durability under extreme conditions
  • Complete main bearing set includes all bearings needed for installation

MICHIGAN 77 bearings are manufactured by Mahle/Clevite, a trusted name in engine bearing technology. The H-Series line was developed primarily for professional racing but is suitable for all types of high-performance engine builds. The extra clearance design helps prevent bearing failure in high-RPM applications and engines with increased oil temperatures.

It was very easy to order my husbands part.

Overall good. Item discription a little vague.

never heard of this site before so i decided to order a small item, super fast shipping and great prices. when my shifter came in it was in perfect condition. i will be doing business with Autoplicity again.

Need more through descriptions on products

I hope the part fits my car

Wow what a deal on mu Subaru husky liner floor mats and low shipping thanks Autoplicity

so far so good we will see how soon I receive it

Always been happy with products and price.

Autoplicity agent was very helpful over the phone. He answered all my questions & even did some research to make me feel comfortable I was getting the appropriate parts I needed for my car. I was very pleased & will shop Autoplicity again.

Best price online for the programmer I ordered. Fast and reasonable shipping costs.

Autoplicty had the best price by far for a transmission. Fast shipping too!<br>UNFORTUNATELY...FED-EX beat the hell out of it! It was hanging out of the box when it arrived but was not damaged other than a few scrapes. Fed-Ex is not the best way to ship 140lbs...they can't lift it! Oh, and they can't comprehend "this side up" either!

Lowest prices, free and fast shipping, excellent product.
