Discover the difference between KING RACING STD and STDX bearings! Learn when to choose STDX bearings for optimal engine lubrication and performance.
ACL Race HX bearings are designed to give extra oil clearance compared to the standard Race H (Std) set—typically about +0.001" (0.025 mm) on a standard-size shaft. That can help maintain a stable oil film and heat control in hard-use engines, but only if the final clearance is verified by measurement. Pick HX blindly and you may trade safety margin for low hot oil pressure or faster wear.
This guide is for builders and enthusiasts who want a correct, repeatable way to decide: what HX really changes, when it’s justified (track, drift, high oil temps), how clearance “grades” can be tuned, and which myths cause the most expensive mistakes.
