Product Details

The ACL Bearings 8B634H-001 is a high-performance Race Series connecting rod bearing set engineered for Ford Small Block V8 engines including 221, 255, 260, 289, and 302 cubic inch applications. This H-Series bearing set features a .001" oversize dimension designed for precision engine builds requiring specific tolerances.

Advanced Tri-Metal Construction:

  • Tri-metal design with lead, tin, copper, and nickel barrier layer for superior strength and seizure resistance
  • High strength overlay with reduced thickness for improved fatigue properties and enhanced durability
  • Hardened steel backing on all rod bearings to maximize bearing lining support and retention
  • Manufactured to exacting tolerances with precise wall thickness accuracy for consistent clearances

Performance Engineering Features:

  • Increased eccentricity compensates for bore distortion during high RPM operation
  • Enlarged inner diameter chamfers accommodate large fillet radius on performance crankshafts
  • Flash plating eliminated on bearing backs for improved heat transfer and housing grip
  • Designed to withstand harsh operating conditions beyond casual driving applications

ACL Race Series bearings are the choice of professional engine builders and are proven in demanding motorsport applications including drag racing, drifting, and rally competition. The H-Series designation indicates standard oil clearance, making these bearings ideal for high-performance street engines and race builds. Proper bearing clearance measurement is essential before installation to ensure optimal performance and reliability.

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

It was ok

I ordered from Autoplicity because they had the lowest price for an exhaust i was looking for. I was kind of iffy at first but then i read all the great reviews. Very fast shipping and delivery! I will be coming back for my next auto needs. Thank you autoplicity for your great prices and customer service!

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available. The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame. So far the service has been great and I look forward to continued great service.

i received item very prompt and for a great price!

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Fast and inexpensive. Thanks.
