GMC For Chevrolet GMC 2004 GMC 3.5L 105350 Engine Forged Crankshaft For Gmc Canyon Chevrolet Colorado 3.5l – OEM 105350

Product Overview: This precision-machined engine crankshaft is a direct-fit replacement component engineered for Chevrolet GMC GMC 3.5L engines. The part is manufactured to original equipment dimensions, making it a practical solution when an original crankshaft has failed through bearing wear, scoring or fatigue cracking.

Key Features: The crankshaft is CNC-machined on precision centres to hold main and rod journal diameters, fillet radii, stroke and end-float within original equipment limits. Journals are ground and micro-polished to a fine surface finish to encourage reliable oil-film formation and reduce bearing wear during cold starts and sustained high load. The oil holes are positioned and deburred to original specification, helping maintain oil pressure and bearing cooling. Precision-machined construction provides the stiffness needed under load, and each shaft is balanced to reduce vibration and bearing stress.

Vehicle Compatibility: It fits Chevrolet GMC models including CANYON. Listed production years include 2004. The same engine family was produced in more than one revision, so verify the engine code and original part number against the removed component before ordering.

Specifications: Key specifications: engine code GMC 3.5L; material high-grade alloy; size STD; condition New; warranty 12 Months. Purpose is replacement and repair of the original component in standard form. The component is a new part rather than a reconditioned exchange unit.

OEM / Reference Numbers: No alternative reference numbers are published for this listing; identification should be made from the engine code and vehicle application details.

Applications: Typical uses include engine overhauls, bottom-end rebuilds, fleet maintenance and repair of vehicles withdrawn from service because of bearing failure or bottom-end noise. It also suits preventative maintenance programmes where a failed unit is replaced before secondary damage occurs. The part is a sensible stock item for workshops that service this engine family regularly and want to minimise vehicle downtime.

Benefits / Replacement Information: Fitting this part corrects bottom-end noise and vibration, restores oil pressure and returns the engine to reliable service. It removes the cost and downtime of reconditioning an original shaft, since the replacement arrives ready for installation in standard size. The unit provides main-dealer-equivalent dimensions at a more economical price point for repair budgets.

Installation or Fitment Notes: Before fitting, confirm the part number, measure the main and rod journals, and check the block line bore and bearing tunnel condition. Fit new bearing shells, verify clearances against factory limits, and torque the caps in the specified order. Confirm thrust clearance, prime the lubrication circuit, and observe a careful running-in period with fresh oil. Record the fitted part number and mileage in the service history so future maintenance references the correct replacement.
