Armker Main & Rod Bearing Set for Hyundai & Kia 2.4L/2.0L — OE-fit kit with thrust washers

Armker Main & Rod Bearing Set is a full replacement kit—including main bearings, rod bearings and thrust washers—designed to restore correct crankshaft and connecting rod clearances on compatible Hyundai and Kia 2.4L and 2.0L engines.

When an engine shows excessive end play, knocking, or oil pressure fluctuations, worn main and rod bearings are often the root cause. This Armker kit supplies the components needed to rebuild the bearing surfaces on a range of Hyundai and Kia 2.4L GDI and 2.0L turbocharged engines. The set is manufactured to match OE dimensions and comes packaged with the parts most commonly required for an in-frame bearing job.

Which vehicles and engines will this Armker set fit?

This kit is engineered to work with specific Hyundai and Kia four-cylinder engines from model years listed by the manufacturer. It covers both naturally aspirated 2.4L THETA engines and 2.0L turbo variants used across Sonata, Santa Fe Sport, Optima, Sorento and Sportage lineups.

• Hyundai Sonata (2012–2016) 2.4L and 2.0L turbo; Santa Fe Sport (2013–2018) 2.0L and 2.4L.
• Kia Optima (2011–2016) 2.4L and 2.0L turbo; Sorento (2012–2018) and Sportage (2011–2016) specific engine fits.
• Refer to OE cross-reference numbers like 21020-2G100, 23060-2G020, 21030-25000 when confirming fit.

What exactly is included in the kit and why those pieces matter?

The package supplies everything typically replaced during a bearing service so you won’t need to source separate parts. Main bearings support the crankshaft journals while rod bearings allow the connecting rods to rotate smoothly on the crank pins; the thrust washers control axial end play.

• 10x main bearing shells sized for the crank journals.
• 8x rod bearing shells for each connecting rod big-end journal.
• 2x thrust washers to manage crankshaft axial movement.
• Manufactured to match original dimensional tolerances for proper oil clearance.

How do these bearings perform and what are the installation benefits?

Armker bearings are produced from high-strength bearing materials and processed to OEM-style clearances to reduce wear and maintain stable lubrication films. They are intended as direct-fit replacements, so installation is straightforward when following proper bearing installation and torque procedures.

• Precision manufacture for consistent journal fit and clearance control.
• Direct-replacement design simplifies installation—no modification required.
• Stable material composition reduces the chance of premature wear under normal operating conditions.

How do I verify compatibility and reference OEM part numbers?

Always cross-check your vehicle’s engine code and the OEM part numbers before ordering. Match the kit’s listed reference numbers to the numbers stamped on your original bearings or the parts catalog to ensure correct selection.

• Compare engine displacement and year ranges: 2.4L GDI or 2.0L turbo specifics are listed above.
• Use OE references like 21020-2G020, 23060-2G400, 21030-25000 for confirmation.
• If uncertain, provide VIN and engine code to a technician or customer support for verification.

Who is this for: This Armker Main & Rod Bearing Set is aimed at DIY mechanics, professional rebuild shops and anyone performing an engine in-frame rebuild or crankshaft service on compatible Hyundai and Kia four-cylinder engines. It’s intended for repairs where restoring correct bearing clearances and controlling crank end play are required. If you need help confirming fitment for your specific vehicle, include your VIN and engine code when contacting support or before purchase.
