Lowering a 1978–1993 Dodge Ram Charger D100/D150 requires careful consideration of suspension modifications, particularly when using upper and lower control arms. This classic truck platform offers excellent potential for stance improvement while maintaining functionality. The factory suspension design provides a solid foundation for lowering modifications, making these vehicles popular among enthusiasts seeking improved aesthetics and handling characteristics.
The Ram Charger series featured robust construction with independent front suspension and solid rear axle configuration. Understanding the original suspension geometry becomes crucial before attempting any lowering procedures. Factory specifications typically provided generous ground clearance for off-road capability, leaving considerable room for lowering modifications without compromising daily driving requirements.
Understanding the suspension geometry of Ram Charger D100/D150
The front suspension system utilizes torsion bar technology combined with upper and lower control arms, creating a reliable independent setup. This design allows for precise adjustment of ride height through torsion bar adjustment bolts. The upper control arms connect to the frame through rubber bushings, while lower arms feature ball joints that support steering knuckles and brake assemblies.

When lowering these vehicles, preserving proper alignment angles becomes essential for maintaining safe driving characteristics. The suspension travel must remain adequate to prevent bottoming out during normal driving conditions.
Ball joint angles change significantly when lowering is performed incorrectly. Excessive lowering can bind ball joints, creating premature wear and potential safety hazards. Professional alignment after any suspension modifications ensures proper wheel positioning and prevents irregular tire wear patterns. Understanding these geometric relationships helps determine appropriate lowering limits for each specific application.
| Component | Factory Specification | Lowered Range |
|---|---|---|
| Front ride height | 8.5-9.0 inches | 6.0-7.5 inches |
| Rear ride height | 9.0-9.5 inches | 6.5-8.0 inches |
| Caster angle | 2-4 degrees positive | 3-5 degrees positive |
Selecting appropriate upper and lower control arms for lowering
Aftermarket control arms specifically designed for lowering applications provide improved geometry compared to factory components. These arms often feature adjustable lengths, allowing fine-tuning of suspension angles and ride height. Quality manufacturers offer arms with improved bushings and stronger construction to handle modified suspension loads.
Upper control arm selection focuses on maintaining proper ball joint angles while achieving desired lowering. Many aftermarket options provide extended ball joint mounting positions, correcting geometry issues common with lowered vehicles. These modifications help maintain factory-like handling characteristics while achieving aggressive stance.

Reinforced construction becomes important as lowered vehicles often experience increased stress on suspension components. Professional-grade arms feature improved materials and enhanced durability for modified applications.
Here are key considerations when selecting control arms for lowering :
- Ball joint compatibility with existing steering components
- Bushing quality for long-term reliability and performance
- Adjustability features for fine-tuning suspension geometry
- Material construction and reinforcement for durability
- Manufacturer reputation and warranty coverage
Step-by-step installation process for lowered Ram Charger
Beginning the installation requires proper vehicle preparation and safety measures. Lifting the truck securely using appropriate jack stands ensures safe working conditions. Removing wheels provides access to suspension components and allows for easier manipulation of control arms during installation procedures.
Disconnecting the torsion bar adjusting bolts reduces spring tension, making control arm removal safer and easier. Supporting the lower control arm with a floor jack prevents sudden dropping when ball joint connections are separated. This precaution protects brake lines and other components from damage during disassembly.

Ball joint angles must be verified throughout the process to ensure proper geometry. New control arms should be positioned to maintain optimal suspension travel while achieving desired ride height reduction.
Final adjustments involve setting torsion bar tension to achieve target ride height. Professional alignment following installation ensures proper wheel positioning and optimal handling characteristics. Road testing helps identify any issues requiring additional adjustment or correction before regular driving resumes.
Achieving optimal performance with lowered suspension setup
Fine-tuning the lowered suspension requires attention to multiple factors affecting ride quality and handling. Shock absorber selection becomes critical as lowered vehicles often benefit from shorter travel dampers designed for reduced suspension movement. Quality shocks designed for lowered applications provide better control and improved ride characteristics.
Tire and wheel selection significantly impacts the final appearance and performance of lowered Ram Chargers. Larger diameter wheels with lower profile tires complement the reduced ride height while maintaining adequate sidewall protection. Proper sizing prevents tire rubbing issues common with aggressive lowering modifications.

Increased stress on components requires more frequent inspection of bushings, ball joints, and alignment settings. Proactive maintenance prevents premature wear and ensures continued safe operation of the lowered vehicle.
