Key Features
This is a direct-fit replacement rear differential for the 2020 Chrysler 300. We started stocking this unit in early 2026, and it’s quickly become one of our steady sellers in the axle and drivetrain category. The reason is straightforward: it’s a well-built, reliable component that gets the job done. When we unboxed it for inspection, the fit and finish were consistent with the manufacturer’s specifications. The housing is solid, the mounting points are cleanly machined, and the overall construction feels durable—exactly what you need for a critical drivetrain component. Our customers report that installation is straightforward for a qualified mechanic, and it restores the factory driving characteristics to the vehicle.

Pros and Cons
✅ Pros:
- Proven Reliability: Based on our sales data, we’ve had zero warranty claims on this specific product in over a year. That’s a strong indicator of its durability.
- Cost-Effective Solution: At just over $600, it provides a solid balance between a risky used part and a very expensive new OEM unit.
- Factory Fit: In our handling, the mounting points and physical dimensions match the original equipment, making a mechanic’s job easier.
- Ready Availability: We keep it in stock. You’re not waiting weeks for a backorder to clear.
- Quality Inspection: We’ve handled it. The construction is well-machined and the finish is consistent, with no obvious defects or damage.
❌ Cons:
- Core Charge: Like most differentials, a core is usually required, which means an extra step and potential charge if yours isn’t returnable.
- Requires Professional Installation: This is not a DIY project for most people. Proper setup of gear lash and bearing preload is critical.
- Condition Variance: As a salvaged/remanufactured part, external appearance may show minor wear, though functionality is verified.
Who Should Buy This?
Buy this if: You own a 2020 Chrysler 300 with a failing rear differential and need a reliable, cost-effective replacement that fits right the first time. You value a part with a track record (our 4.5/5 customer satisfaction across 23 buyers speaks to that) and want it shipped quickly from a source that has physically inspected it.
Skip this if: You are looking for a brand-new, in-the-box OEM part with a multi-year warranty and are prepared to pay a significant premium. Also, if you need a differential for a different model year or a performance gear ratio change, you’ll need to look elsewhere.
Frequently Asked Questions
Is this a new or used differential?
This is typically a remanufactured or quality salvaged unit. It has been inspected to ensure it is a functional, direct replacement. The condition is reflected in the price and warranty.
How do I know the gear ratio is correct?
The ratio is specific to your vehicle’s original build. We strongly recommend providing your VIN at checkout so we can confirm the correct match. Installing the wrong ratio will cause major drivetrain issues.
Do you offer an installation guide?
We do not provide step-by-step installation guides for complex drivetrain components. This job requires specialized tools and knowledge for setting gear mesh and bearing preload. We recommend professional installation.
What is included in the 30-day warranty?
Our warranty covers defects in the unit that cause it to be non-functional upon installation. It does not cover damage due to improper installation, incorrect fitment, or wear from use. Given our zero-claim history on this part, we’re confident in its condition.
Where can I buy a 2020 Chrysler 300 rear differential online?
You’re in the right place. Salvagepartsusa stocks this specific differential and ships it directly from our Houston, TX warehouse. You benefit from our hands-on inspection and same-day shipping.
How is the differential packaged for shipping?
We use heavy-duty packaging to protect this dense component. It’s secured to prevent internal damage during transit and shipped in discreet packaging.
What is the core charge and process?
A core charge is usually applied at checkout. Once you install the new differential, you return your old, complete core unit to us in the provided packaging. Upon receipt and inspection, we refund the core charge.
