RCD suspension parts are a popular choice among off-road enthusiasts who want to improve their vehicle's handling, ride quality, and durability on rough terrain. Whether you drive a truck, Jeep, or SUV, upgrading your suspension with RCD components can transform how your vehicle performs both on and off the pavement. This guide covers the key RCD suspension parts, what they do, and how to pick the right ones for your build.
What Are RCD Suspension Parts?
RCD (Race Car Dynamics) is an aftermarket suspension brand that specializes in high-performance shocks, coilovers, lift kits, and related components. Their products are engineered for off-road use, focusing on increased wheel travel, better damping control, and improved structural strength. RCD parts are commonly used for rock crawling, desert running, and overlanding.
Types of RCD Suspension Parts
Coilover Kits
RCD coilover kits combine a shock absorber and coil spring into a single unit. They allow for adjustable ride height, spring preload, and sometimes rebound damping. These kits are ideal for vehicles that need a moderate lift (2-3 inches) while maintaining excellent on-road manners. RCD coilovers are valved specifically for different vehicle weights and intended uses, so choosing the right kit matters.
Remote Reservoir Shocks
For serious off-roading, RCD offers remote reservoir shocks. The reservoir holds extra oil and nitrogen, which helps keep the shock cool during hard use and prevents fade. These shocks have larger bodies and more precise valving, providing consistent damping over rough terrain. They mount externally, often with a hose connecting the reservoir to the shock body.
Lift Kits
RCD lift kits come in various heights, typically from 3 to 6 inches, and include all necessary hardware such as springs, shocks, control arms, and sway bar links. A full lift kit maintains proper geometry and axle alignment, preventing excessive wear on drivetrain components. RCD lift kits are designed to work with factory electronic systems like air suspension or terrain management.
Performance Springs
If you only need a small lift or want to improve load carrying, RCD performance springs are an option. They are stiffer than stock and resist sagging under heavy loads. Pair them with RCD shocks for a matched system.
Benefits of Upgrading to RCD Suspension Parts
- Better off-road traction: RCD components allow your wheels to stay in contact with the ground over bumps and dips, increasing grip.
- Improved ride quality: On rough roads, RCD shocks absorb impacts without jarring the cabin.
- Increased ground clearance: Lift kits help you clear obstacles and prevent undercarriage damage.
- Longevity: RCD parts use high-grade materials like 4130 chromoly steel and aluminum, resisting corrosion and fatigue.
- Adjustability: Many RCD parts allow tuning of ride height and damping to match your driving style.
How to Choose the Right RCD Suspension Parts
Determine Your Vehicle and Model
RCD produces parts for specific makes and models. For example, Ford F-150, Jeep Wrangler, Chevrolet Silverado, and Toyota Tacoma. Always verify compatibility using your year, model, and trim. RCD may have different kits for models with or without factory air suspension.
Define Your Driving Needs
- Daily driver with occasional light off-roading? A mild coilover lift (2-3 inches) with adjustable damping is a good balance.
- Rock crawling or heavy trail use? Go with a full lift kit (4-6 inches) and remote reservoir shocks for maximum articulation and cooling.
- Overlanding with heavy gear? Choose springs that accommodate added weight and shocks with a focus on load control.
Consider Wheel and Tire Sizes
Larger tires require more lift and may need fender trimming or bumper modifications. RCD lift kits often list maximum tire sizes for each lift height. For example, a 4-inch lift might clear 35-inch tires, but a 6-inch lift may fit 37s. Always check clearance before buying.
Check Component Quality
RCD parts are CNC-machined and assembled with precision seals and bushings. Look for features like:
- Cadmium-plated shock bodies or zinc coating for rust resistance.
- Greaseable bushings or spherical bearings in control arms.
- Adjustable coilover springs with dual rate options.
Installation and Maintenance Tips
- Professional installation recommended: Suspension work involves heavy components and critical alignment specs. If you are not experienced, hire a shop that has installed RCD kits before.
- Alignment after lift: A lift changes your vehicle's geometry. After installing RCD parts, get a professional alignment. Some RCD lift kits include adjustable control arms to correct caster and camber.
- Break-in period: New shocks and springs need about 500 miles to settle. Check all bolts for torque after break-in.
- Regular maintenance: Clean shock shafts, check for leaks, and inspect bushings every oil change. Remote reservoir shocks may need nitrogen recharge every 2-3 years.
Common Mistakes When Buying RCD Suspension Parts
- Mixing brands: Combining RCD shocks with other brand springs or lift components can result in poor ride and handling. Stick with a complete RCD system.
- Ignoring weight accessories: If you bolt on a winch, steel bumpers, or a roof rack, factor that into spring selection. RCD offers spring rates for stock vs. heavy loads.
- Buying too much lift: More lift isn't always better. Tall lifts raise your center of gravity, hurting on-road stability. Choose the minimum height that meets your tire and clearance needs.
Practical Recommendations
For most off-roaders, the RCD Pro-3 Coilover Kit with remote reservoir is an excellent upgrade. It offers 3 inches of lift, adjustable damping, and enough wheel travel for moderate trails. If you plan to run 35-inch tires and hit serious trails regularly, consider the RCD 4.5-inch Lift System with bundled control arms and shocks. For heavy-duty use like overlanding with a loaded vehicle, the RCD 6-inch Performance Lift with dual rate springs provides the load capacity and articulation needed.
Before buying, contact RCD's customer service or a specialist dealer to discuss your exact build. They can recommend the best parts and tell you what additional modifications (like extended brake lines or bump stops) you might need. Investing in quality suspension parts improves safety and enjoyment both on and off the road.
