Product Details

The ACL Bearings 4M1183-.25 is a complete main bearing set engineered for high-performance engine builds and precision rebuilds. This standard size bearing set features ACL's tri-metal construction with a steel backing, copper-lead intermediate layer, and tin-aluminum overlay for superior strength and wear resistance.

Key Features:

  • Standard size (-.25 designation indicates undersize specification)
  • Tri-metal construction for enhanced durability and load capacity
  • Precision machined to OEM tolerances for proper oil clearance
  • High-temperature resistant design for demanding applications
  • Complete set for all main journal positions
  • Compatible with both stock and performance crankshafts

ACL Race Series bearings are manufactured using advanced materials and strict quality control processes to ensure consistent performance under extreme conditions. The tin-aluminum overlay provides excellent embedability of dirt particles while maintaining a strong bond to the bearing substrate, making these bearings ideal for street performance, racing, and engine rebuilding applications.

Easy, customer-friendly online shopping. I am satisfied.

I am very pleased with the quickness my product was shipped. I have had problems with other products i have ordered once again Thank You.

Perfect transaction. Perfectly satisfied. Best price anywhere, same-day shipping. Couldn't be happier. Thanks Autoplicity.

Super fast shipping. Got my product in 2 days with standard shipping option. Best Price I found on the afe dry pro s filter online as well!

Ordered front & back WeatherTech Digital Fit floormats for my Tacoma, and they arrived 2 days later! Will definitely use again in the future.

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

Extremely impressed with Autoplicity!!!! I am a very loyal Amazon customer and ALMOST paid a 20% premium on my Thule bike rack to go with old faithful. Very glad I didn't, as I saved $50 and received my product with free shipping FASTER than Amazon Prime!!!

Great shipping speed great site. Awesome!!! Thanks guys I love my new bumper.

Great priced items. was WAY under what others wanted. shipped fast also. A+ seller. I will buy from again.

I recently ordered 2 autometer gauges for my truck from Autoplicity. The order arrived 3 days later on my door step. The gauges are beautiful and I cant wait to install them.. Thanks Autoplicity!

I think I had to remind them to ship my item but once I did it shipped the next day. The package had the wrong label on it so I wondered if I got the right item but I did and all is well.
