    141M is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Excellent offering Would if I could, give these 10 STARS !!! Old school bearings with the copper lead alloy on steel backs with new tech dry film coating ! Can't do any better. I went with a set of silicon aluminum once in one of my race engines, never again. Ruined my crank and seen others go bad too. The 270 degree oil groove can't be improved upon, much better for rod oiling along with enough lower half support to let the crank live a happy life. For any engine other then a stock build" " don't settle for a stock bearing !!! Give those rods/pistons and cylinder walls even cam lobes every chance for lube as possible. As for other ratings, no one beats Jegs on these, seen the same part number listed for a lot higher price elsewhere! These are near next on my list of needed parts for my current build. Almost forgot to rate ease of install. That depends on your skill level and vehicle ?

    Rated 5 out of 5 by from Excellent quality, just what you'd expect from Sealed Power products. I bought these to freshen up my large cubic inch engine. When I installed these, the old bearings looked awesome. Don't let the black finish fool you, these are some tough bearings.
