Product Details

ACL Race Series main bearings are engineered for high-performance and racing applications where durability and precision are critical. The 5M1633H-.025 features an undersized design at -.025" (0.025 inches undersize) to accommodate machined crankshafts, allowing for proper bearing clearances after crankshaft grinding or reconditioning.

Key Features:

  • Race Series construction designed for extreme engine loads and high RPM operation
  • -.025" undersize specification for reground crankshaft journals
  • Tri-metal bearing construction for superior strength and wear resistance
  • Precision-manufactured to strict tolerances for optimal oil clearance
  • Enhanced fatigue resistance for demanding racing conditions
  • Compatible with both synthetic and conventional racing oils

ACL's Race Series bearings utilize advanced metallurgy and coating technologies to provide maximum protection under severe operating conditions. The undersize dimension allows engine builders to restore proper bearing clearances when machining is required to remove crankshaft journal damage or wear.

very good price fast shipping

Easy check out I like the PayPal option

i found the best deal on the web on an ARB bumper here and shipping was also the lowest ive seen, so long 4wheelparts.com i found a new place to shop.....

GOOD SERVICE, FAST SHIP, CHEAP PRICE

Found the best price on my High Rock 4x4 Overhead Rack. They even discounted the shipping for me. Quick to ship and provide tracking info. Very happy with the way this company operates.

Although there was a mix up with the shipping on my order customer service was helpful and expedited the solution and made it worth my trouble. I will be keeping Autoplicity in mind for any other parts I might need for my Jeep.

Very easy order to place, can't wait to get my part in!!thanks
