Celebrating our 10 Year Anniversary (2017-2026)

Rear-wheel-drive Dodge Charger, Challenger, and Chrysler 300 platforms use an independent rear suspension system that relies on multiple mounting points to keep drivetrain components aligned and supported. The rear differential is a key part of that system. It transfers power from the driveshaft to the rear wheels while managing load changes during acceleration, shifting, and normal driving. Because the differential works as part of a connected drivetrain system, its mounting

Bushings play an important role in how drivetrain components are supported and how movement is managed within a vehicle. When comparing street and track bushings, the difference comes down to how much movement is allowed and how that affects overall feel and comfort. Understanding these differences can help clarify why different options exist and how they are typically used. What Are Bushings? Bushings are components used to connect parts of the drivetrain and suspension whil

A clunking sound when shifting gears or getting on and off the throttle is a common concern in rear-wheel-drive vehicles like the Dodge Charger and Challenger. While the sound can vary, it is often related to movement within the drivetrain system. Understanding where this noise comes from begins with how the drivetrain transfers power and how its components are supported. How the Drivetrain Transfers Power In rear-wheel-drive vehicles, power flows from the engine through the

RWHP stands for Rear-Wheel Horsepower . It is a measurement of the power delivered to the rear wheels of a vehicle, rather than the power produced at the engine itself. RWHP is commonly used in drivetrain and vehicle engineering discussions because it reflects the power that actually reaches the ground after passing through the drivetrain. RWHP vs Engine (Crank) Horsepower Engine horsepower—often referred to as crank horsepower—is measured at the engine output shaft, before p
