Does the kit include crank and crankshaft bearings?

Yes, both families are announced and illustrated. The photos also show cheek halves; the exact nomenclature delivered must be confirmed before intervention.

What motors are advertised for these bearings?

The title and banner from Anamoparts cite the 6.2 L LT1, LT4, and L86 GM V8 motors. The actual motor installed, the references, and the dimensions must match the ordered set.

Is the kit compatible with all Escalade, Silverado, and Yukon models up to 2024?

No. The supplier's periods group different versions and are not sufficient to validate a fitment. You must identify the motor code and check the references by VIN.

Are the bearings in STD grade?

No standard size or repair is specified for this variant. The MS-2339A reference is available in several sizes in the MAHLE catalog; its presence in the listing does not specify the size of the Anamoparts kit.

Which references appear in the photo?

The headband shows CR8057MC, MB5383MC, 12656817 and 12656812. The text adds 12656814, 12683811, 12729655 and MS-2339A, to be matched separately with the required parts.

What checks should be performed if the crankshaft has been ground?

The workshop must measure the main journals, crankpins, and bearing housings, then determine the appropriate bearing sizes and clearances according to the motor procedure. Displacement and a reference value do not replace these measurements.

Product details

This Anamoparts bearing set is designed for rebuilding the GM V8 6.2 L lower engine, with the LT1, LT4 and L86 codes announced. It combines the connecting rod shells and the crankshaft main bearing shells, including flanged elements visible in the photos.

Two functions combined for the lower engine

Connecting rod bearings are located between the connecting rod big ends and the crankshaft journals; main bearings fit the block bearings. Their geometry and size correspond to different locations: the two families are not chosen solely based on displacement.

The two photos show groups of narrow shells and a wider group with grooves, passages and flanged elements. The supplier indicates copper and aluminum, without specifying the composition of each layer or any particular coating.

References provided for the set
Source of the reference	Complete numbers to cross-reference
Photographed label	CR8057MC ; MB5383MC ; 12656817 ; 12656812
Other references from the description	12656814 ; 12683811 ; 12729655 ; MS-2339A

The presence of these numbers in the same listing does not mean that each reference alone designates the connecting rod and crankshaft assembly, nor an identical size.

Announced applications: identify the engine actually installed

The table lists the main applications cited by the supplier. The periods cover several versions: they do not validate all vehicles of the same range. The engine code and VIN must be used to match the bearing references corresponding to the vehicle.

The LT1, LT4 and L86 designations remain the announced target of the set. The period up to 2024 does not allow extending this target to another engine code, even on a 6.2 L V8.Select the size based on crankshaft measurements

No standard or repair size is specified for the proposed variant. After removal, have the dimensions and condition of the main journals, rod journals and housings measured, then determine the necessary clearances according to the engine procedure. A ground crankshaft requires a selection adapted to its machining.The

MAHLE LS Engine Product Listing catalogue, page 47 lists MS-2339A as a main bearing set and offers it in several sizes. This base reference therefore does not prove that the Anamoparts set offered is STD size.

Prepare the inventory before rebuilding

Provide the workshop with the engine code, references of the removed parts and the measurement results. Have the delivered nomenclature, shell thickness and passage configuration confirmed before assembly. The photos do not constitute a dimensional survey and do not show pistons, connecting rods or rebuilding mounting hardware.
