Construction & Design:
ACL Race Series bearings are crafted using a tri-metal layering process that combines a steel backing with a copper-lead alloy and a thin overlay of a soft, anti-friction material. This construction provides a balance of strength, conformability, and embedability, allowing the bearing to adapt to minor crankshaft imperfections while resisting wear and fatigue.
The bearing surfaces are precision-machined and finished to exacting standards, ensuring optimal oil clearance and film retention. This meticulous design reduces metal-to-metal contact, minimizing friction and heat generation during engine operation. The result is a bearing set that supports high-performance engines reliably over extended periods.
Installation & Fitment:
Installation of the ACL Race Series main bearing set is straightforward for experienced engine builders and mechanics. These bearings are designed as direct replacements for factory main bearings in Chrysler 5.7L and 6.1L Hemi V8 engines, fitting a broad range of vehicles including Dodge Ram 1500 (2003–2025), Chrysler 300 (2005–2010), Dodge Magnum (2005–2008), Jeep Grand Cherokee (2005–2021), Dodge Charger (2006–2025), Dodge Challenger (2008–2025), Dodge Durango (2021–2025), and Ram 1500 (2021–2025).
