Product Details

The Sealed Power 140M1X is a high-performance main bearing set engineered for demanding racing and competition applications. This Competition Series bearing set is designed specifically for Small Block Chevy 400 engines and features a 0.001-inch undersize for increased clearance in performance builds.

Key Features:

  • Tri-metal copper-lead alloy construction for superior durability and load capacity
  • 3/4 groove design on upper and lower bearings enhances lubrication while maintaining maximum bearing surface area
  • Exclusive contoured-flange thrust bearing technology for increased thrust-loading capacity
  • Premium 1020AK steel backing overlaid with H-14 Super Duty Alloy for greatest load-carrying capacity
  • Nickel barrier with lead-tin-copper overplate for enhanced protection
  • DUROSHIELD coating provides protection against dry starts and interrupted oil supply conditions
  • Proven performance in NASCAR, NHRA, and IHRA competition

Sealed Power Competition Series bearings are engineered to withstand the punishing conditions of high-performance and racing engines. The bearing is manufactured thinner than standard specifications to provide 0.001 inch of additional clearance, making it ideal for performance engine builds requiring precise tolerances. These bearings feature application-specific materials and alloys designed for corrosion resistance, decreased wear rates, and increased fatigue strength.

great pricing and fast shipping

My initial review was 1 star because I ordered a Thule rooftop cargo box, but cancelled the order after Autoplicity called me about collecting extra money to ship the item after their website did not charge me enough for shipping. After my initial review Autoplicity offered to ship the item totally free since the issue was a flaw in their website. This was unexpected, above and beyond in my opinion. I have yet to receive the item but commend Autoplicity's customer service

I was looking to buy a gale banks header for my jeep. I came across this site th eir price was nearly $100 cheaper than any one else. Fast shipping too. Thank you.

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

quick and convenient

Product arrived fast and as described. The best price I found online. Packing was excellent, highly recommend Autoplicity.

Great Company. I needed a part quickly and for the right price. They had the best price on the internet, and made sure it got to me in two days before I went away on my road trip. I spoke to a representative that was very helpful. I highly recommend Autoplicity! Thanks!!!

Great site! Just what I wanted!
