Part numbers include 5M8309H and 4B8296H for the EJ, 5M1985H and 4B1972H for the K20C1, and 6M5587H for the Audi 2.5T mains. Most sets come in several sizes, including an HX extra clearance option, and ACL sets usually ship in 3 to 5 days. We ship Australia-wide from the NSW Central Coast.

The Race Series range is engineered for the high cylinder pressures and high RPM of modern motorsport, using a hardened lead-tin-copper overlay and high-strength steel backing to resist bearing fatigue under thermal load.

Choosing the Right Part

ACL part numbers are engine-specific, so confirm the following before ordering:

Engine code: EJ20/EJ22/EJ25, FA20, K20C1, 2.0 TSI or DAZA/DNWA 2.5T FSI.
Bearing position: main bearings or conrod (rod) bearings. These are sold as separate sets.
Journal size and thrust position: Subaru EJ sets are listed by 52mm journal and thrust position 5, so check your crankshaft specification.
Size: standard, oversize or undersize to suit a ground crank, or the HX variant, which adds 0.025mm (0.001") of oil clearance for high-load racing applications.
Audi 2.5T FSI rods: the ACL rod bearings for the five-cylinder suit aftermarket connecting rods only. Factory rods need genuine Audi bearings, so plan rods such as Carrillo connecting rods into the build.

Installation & What You'll Need

Engine bearings are a precision, tolerance-critical component. Installation by a professional engine builder is recommended.

Measure crankshaft journals and rod/main housing bores, and check assembled oil clearances against your target specification.
Have the correct torque specifications and fasteners on hand for your rods and main caps.
Use clean assembly lubricant and ensure bearing shells, saddles and caps are spotlessly clean before fitting.
Confirm bearing tang alignment and thrust position orientation during assembly.

FAQ

Where can I buy ACL bearings in Australia?

Chicane Australia carries ACL Race Series main and conrod bearings and ships Australia-wide from the NSW Central Coast. Shop by vehicle above, search by ACL part number, or email our team your engine code, chassis code and required clearance for help.

Are these genuine ACL bearings?

Yes. Chicane Australia supplies genuine ACL Race Series bearings, listed by ACL part number, for example 5M8309H mains and 4B8296H conrods for the Subaru EJ.

Can you supply the HX extra clearance bearings?

Yes. HX bearings provide an additional 0.025mm (0.001") of oil clearance for high-load racing applications. Choose the HX option on the EJ, K20C1, 2.0 TSI and Audi 2.5T listings.

Can I use the ACL Audi 2.5T rod bearings with factory rods?

No. The ACL rod bearings for the Audi RS3 and TT RS 2.5T FSI suit aftermarket connecting rods only. Factory rods need genuine Audi bearings.

What is the difference between ACL Race Series and standard replacement bearings?

Race Series bearings use a hardened lead-tin-copper overlay and a high-strength steel backing to withstand the higher cylinder pressures and RPM of motorsport use, where standard replacement bearings are designed for factory-output engines.
