2026 Front Complete Strut Assembly Kit for 2012-2018 Chrysler 300 & Dodge Charger: Technical Compliance, DTC Mapping & OEM Cross-Reference is a working reference for owners, technicians, and buyers comparing replacement front struts. It covers what to check before ordering, which codes point at a strut problem, and how to plan a safe install without assuming anything about year, trim, or engine configuration.

The kit ships as a loaded assembly: strut, coil spring, upper mount, bearing, and hardware in one unit. That takes spring compression off your bench and removes the risk of pairing a spring and damper that were never matched.

KOEEP carries it as the Front (2) Complete Struts Assembly For 2012-2019 Chrysler 300 Dodge Charger AWD. Check the fitment notes against your VIN before you pay — the product page spans a wider year range than this bulletin.

What the kit is, and what compliance means here

This technical bulletin covers the 2026 front complete strut assembly kit for 2012-2018 Chrysler 300 and Dodge Charger models. The assembly meets the 2026 aftermarket compliance requirements for fitment, torque specifications, and structural integrity.

The strut carries vehicle weight, absorbs impact, and forms part of the steering axis, so all three checks matter on a front corner. Fitment compliance means the mounting points land where the OE part lands; torque compliance means the documented values match what the assembly is built to hold.

Structural integrity is the one you cannot eyeball in a parking lot — and it is why a complete loaded assembly beats a bargain damper with a reused spring.

DTC mapping: scan the wiring before you buy

A strut-related position sensor failure may register as C0035, C0040, or C0060. Treat those codes as a prompt to inspect the wheel speed sensor lines and the strut wiring before ordering a replacement.

A chafed harness, a bent pin, or a corroded connector can throw the same warning as a failed component, and no new strut will clear a wiring fault. Inspect, fix, rescan — then decide whether the assembly itself needs replacing.

The same discipline applies after the repair. If a warning light stays on, scan the diagnostic codes and verify the fix instead of replacing parts at random.

OEM cross-reference and specifications

Every order should start with the number printed on the part you removed. Match it against the list below, then move on to connector shape, mounting points, and dimensions.

The 60 ft-lb value applies to the strut rod bolts. For the strut-to-knuckle fasteners, take the value from the workshop manual for your exact model year, and finish with a torque wrench — an impact gun distorts both the reading and the joint.

What to verify before ordering

Start with the vehicle year, make, model, engine or drivetrain, and the original equipment number printed on the removed part. A similar-looking component can still be incompatible, so read the fitment notes before you install anything.

• Record the VIN and exact trim level.
• Compare the OE or interchange number and connector layout.
• Check whether the part is front/rear, left/right, or a complete set.
• Inspect nearby components that could cause the same symptom.

Left, right, or a pair?

Struts are side-specific. Mount orientation and line routing differ between corners — confirm left/right before ordering. If both front corners are due, a matched pair keeps spring rate and damping identical across the axle.

Connector layout deserves its own check

Two assemblies can share every dimension and still fail to plug in if the sensor connector changed mid-generation. Photograph the connector on your original part and compare it against the product photos before the box is opened.

Installation and diagnostic checklist

Disconnect power when the procedure requires it, support the vehicle correctly, and follow the workshop manual for torque values and calibration steps. Those values are specific to your build and override anything generic.

• Clean mating surfaces before the new assembly goes in.
• Route wiring away from heat sources and moving parts.
• Torque the strut rod bolts to 60 ft-lb; take the remaining values from the manual.
• Test the repair before the vehicle returns to service.

If a warning light remains on afterward, scan the relevant diagnostic codes and verify the repair — a side-by-side look at the installed and removed parts catches most seating errors.

How to choose the right replacement

Prioritize verified compatibility, material quality, warranty coverage, and clear product photos. For safety-critical systems — brakes, steering, sensors, fuel delivery — use the vehicle-specific specification, not a universal substitute.

Keep the original part until the new component has been test-fitted and confirmed. It stays your physical reference for connector shape, bracket positions, and dimensions if anything needs to go back.

Not every worn corner needs the whole assembly. If the clunk over bumps traces to the top mount only, the dedicated Strut Mount For Chrysler 300 14-05; Dodge Charger 14-07, Magnum 08-05 lets you service that single component instead of the entire corner.
