Product details
This Anamoparts rebuild kit is advertised for the GM LF1 V6 3.0 L gasoline motor. It includes a set of gaskets, pistons with rings, and crankshaft and connecting rod bearings. It is intended for a workshop-prepared motor rebuild, with an advertised bore of 89 mm and dimensions to be matched with the required parts.
An illustrated set for the six cylinders
The photos show six pistons, six pins, twelve clips, and six sets of rings. The sealing section includes two three-port cylinder head gaskets, blue valve cover gaskets, manifold gaskets, and several circular gaskets, including one mounted in a metal holder.
The two sets of half-shells correspond to the advertised bearings. These are plain bearings, not ball bearings. The term "complete" describes the commercial set; it does not guarantee the presence of bolts, timing components, or all parts required for each service.
Dimensions indicated by the supplier Item Advertised value Cylinder bore 89 mm Piston length 51 mm Compression height 29 mm Pin length 52 mm Pin diameter 24 mm Top / second / oil ring heights 1.00 / 1.20 / 1.50 mm Bearing size Not specified in the offered variant Distinguish between bore, pin, and repair size
The 89 mm refers to the advertised cylinder bore: this value does not replace the piston measurement or the assembly clearance. The ring heights are not ring gap measurements. A rebuild after machining requires separately selecting the dimensions of the pistons, rings, and bearings.
One point must be confirmed before ordering: the official Chevrolet specification for the GM 12631195 piston indicates a pin of 52.85 mm, while the advertisement for this kit indicates 52 mm. This source describes a specific GM part; it does not certify the dimensions of the Anamoparts kit or its origin. It also identifies 12631195 as a piston intended for a specific side of the motor.

These periods are supplier indications, to be confirmed with the VIN and the actual engine code installed. The general field mentioning 2010–2016 and Verano is not included as a compatibility extension: the detailed list does not justify it.
Cross-reference numbers provided Family Numbers cited Gaskets HSU26269 ; HS54580 ; CS263761 ; CS54661 Bearings 12585761 ; 12610603 ; 12610604 Pistons 12631195 ; 12631196 ; 12566186 ; 12631194 ; 12654417 ; 12654418 ; 12654439 These numbers serve for component cross-referencing; they do not constitute a unique kit reference nor proof that all pistons are interchangeable. Another section lists 112585761, different from 12585761: have the bearing number confirmed instead of merging these two references.
Prepare the order with workshop measurements
Provide the VIN, engine code, removed references, and measurements taken during disassembly. Clarify the distribution of pistons between the two banks, the bearing size, and the delivered nomenclature. Torque values, clearances, and installation positions must come from the procedure for the relevant motor.

Frequently asked questions
What does the illustrated kit contain?
The images show the seals, six pistons, six pins, twelve clips, six sets of rings, and two sets of bushings. The supplied bill of materials must be confirmed for the planned overhaul.
Does this kit fit all GM 3.0 L motors?
No. The supplier targets the LF1 gasoline V6 engine and certain specific applications. The VIN, engine code, and references for each family must match.
Do the pistons measure exactly 89 mm?
The source indicates a cylinder bore of 89 mm. It does not provide an independent measurement of the actual piston diameter of the kit or their installation clearance.
Why is it necessary to check the axle length?
The kit is advertised with 52 mm axles, whereas the official Chevrolet specification sheet for the 12631195 piston ring indicates 52.85 mm. The delivered dimension must therefore be confirmed.
Are the bushings in standard stock?
No standard dimension or repair is identified in the proposed variant. The selection must be matched to the crankshaft dimensions and housings, particularly after machining.
Are the timing components and cylinder head bolts included?
They are neither illustrated nor explicitly announced in the kit content. Have the additional components required for the intervention confirmed.
Are references 12631195 and 12631196 interchangeable?
Their presence in the same listing does not prove this. The Chevrolet catalog identifies 12631195 for a specific side; the piston distribution of the kit must be confirmed.
