Transfer cases are essential components in heavy-duty trucks, as they enable the distribution of power from the transmission to the wheels and axles. In this article, we will delve into the various transfer case options available for RAM heavy-duty trucks, exploring their functionalities and the advantages they offer.
Clutchless Transfer Case: The RAM Rebel’s Distinction
The 2020 RAM Rebel stands out by featuring a clutchless transfer case, a departure from the clutch-type transfer cases commonly found in other RAM models. This design directly transmits power to both the front and rear driveshafts, enhancing responsiveness and torque capacity.
Clutch-Type Transfer Cases: Modulating Power Distribution
Clutch-type transfer cases, employed in most RAM heavy-duty trucks, provide more precise control over power distribution. These transfer cases utilize a clutch to engage the front driveshaft, allowing drivers to switch between rear-wheel drive and four-wheel drive modes.
Differential Options: Optimizing Traction and Performance
Differentials, connected to the axles, play a crucial role in distributing power to individual wheels. RAM trucks offer a range of differential options, including open, limited-slip, and electronically locking differentials. Open differentials distribute power evenly between wheels, while limited-slip differentials provide increased traction in challenging conditions. Electronically locking differentials ensure equal power distribution, making them ideal for off-road scenarios.
Transfer Case Enhancements for Improved Performance
RAM’s on-demand transfer system has undergone enhancements to boost responsiveness and front output torque capacity. These improvements translate into smoother gear changes and enhanced performance, especially in off-road situations.
Transfer Case Configurations: Impact on Off-Road Capabilities
Different transfer case configurations can significantly impact a truck’s off-road prowess. The clutchless transfer case in the RAM Rebel, for instance, offers better traction and power distribution compared to clutch-type transfer cases. Additionally, welding the rear differential is a popular off-road modification that further enhances traction.
Gen4 and Gen5 Transfer Case Differences
RAM’s Gen4 trucks allowed for manual transfer case clutch lockup override, providing drivers with greater control over power distribution. In contrast, Gen5 trucks, including the Rebel model, feature a clutchless transfer case, while other models utilize clutch-type systems.
Transfer Case Packaging and Design Implications
Transfer case design and packaging can influence other aspects of the truck. For example, the Rebel’s unique DEF tank design is necessitated by the transfer case’s placement. Additionally, the interior view design on RAM’s build page may not always accurately reflect the actual transfer case configuration.
Choosing the right transfer case for your RAM heavy-duty truck depends on your specific needs and driving conditions. Whether you prioritize on-road performance, off-road adventures, or a combination of both, RAM offers a range of transfer case options that cater to your requirements. By understanding the functionalities and differences between these options, you can make an informed decision to optimize the performance and capabilities of your truck.
What are the different transfer case options available for RAM heavy-duty trucks?
RAM heavy-duty trucks offer two main transfer case options:
Clutchless transfer case: This type of transfer case is found in the RAM Rebel model. It directly transmits power to both the front and rear driveshafts, providing a more responsive and efficient power delivery.
Clutch-type transfer case: This type of transfer case is used in other RAM heavy-duty truck models. It modulates power to the front driveshaft through a clutch engagement, allowing for more precise control of power distribution.
– Supports weight of truck and cargo – Absorbs road shocks – Ladder, channel, and tubular types – High-strength steel alloys for durability
– Choose appropriate frame type for vehicle size and weight – Inspect for damage and corrosion
– Forms the backbone of the truck – Must be strong and lightweight
Suspension
– Connects frame to wheels – Absorbs bumps and vibrations – Leaf springs, air bags, coil springs – Ensures weight distribution, traction, and stability
– Select suspension system based on road conditions and cargo type – Regularly inspect and maintain suspension components
– Improves ride quality and safety
Axles
– Support wheels – Transmit weight and torque – Front, rear, tandem axles – Single, dual, or triple axle configurations
– Match axle configuration to load capacity – Inspect axles for wear and damage
– Essential for weight distribution and power transmission
Other Components
– Brakes: Stop and control movement – Driveline: Transmits power from engine to wheels – Wheels and tires: Provide traction and support weight
– Maintain and inspect all components regularly – Use high-quality components for optimal performance
– Ensure safe and efficient operation
Factors Affecting Design
– Vehicle size and weight – Cargo type – Road conditions – Environmental factors
– Consider factors when selecting truck foundations – Design for specific application and environment
– Foundations must meet diverse requirements
Maintenance and Inspection
