1. Suspension Lift Kits: This is the most common and generally the best method for a significant ride height increase. Kits are available in various heights (from a modest 1-2 inches to several inches).
* Body Lift: This raises the body of the truck *above* the frame. It's a relatively simple installation, less expensive, and doesn't affect the suspension geometry as much as a suspension lift. However, it can leave gaps between the body and the frame, requiring body-mount filler blocks or trimming of components. It also doesn't improve off-road capability as much as a suspension lift.
* Suspension Lift: This raises the suspension itself, providing better ground clearance and improved off-road performance. This is more complex to install and more expensive than a body lift. Subtypes include:
* Spacers: These are the simplest suspension lifts, adding spacers between suspension components. They are relatively inexpensive and easy to install but can negatively impact suspension geometry and ride quality. They're best for smaller lifts.
* Lift Springs/Coils: Replacing the factory springs with taller springs increases ride height. This provides better ride quality than spacers but is more expensive and requires more work.
* Lift Blocks: These are added between the axle and leaf springs (if your truck uses leaf springs). Similar to spacers, they're easy to install and affordable for smaller lifts, but they can negatively impact ride and handling. Often combined with other lift methods.
* Longer Shocks: Necessary with any significant lift to prevent shock damage and maintain optimal suspension travel.
2. Larger Tires: Fitting larger diameter tires will increase the ride height slightly, but this will affect your speedometer accuracy and potentially your gearing. You'll likely need to adjust your speedometer calibration or use a speedometer correction calculator. This approach alone won't significantly raise the ride height, but it's a good complement to other methods.
Things to Consider:
* Wheel Well Clearance: Larger tires and a lifted suspension may require trimming or modifying the wheel wells to prevent rubbing.
* Driveshaft Angles: Significant suspension lifts can alter driveshaft angles, potentially leading to vibrations or premature wear. You might need a longer driveshaft or different CV axles depending on the lift height.
* Steering Geometry: Altering ride height can affect steering geometry, potentially causing handling issues. Consider a professional alignment after any lift kit installation.
* Cost: Prices vary widely depending on the type of lift kit and the labor involved. Body lifts are generally the cheapest, while suspension lifts, particularly those with new springs and shocks, can be significantly more expensive.
* Ride Quality: While a lift can improve off-road capability, it may negatively impact ride quality on paved roads, especially with simpler lift methods like spacers or blocks.
Recommendation:
Before making any modifications, determine *why* you need to raise the ride height. If you're only looking for a small increase, larger tires might suffice. For a more substantial lift and improved off-road performance, a suspension lift kit (with new springs and shocks) is the better option, but it will be more involved and expensive. Always research the specific lift kits available for your *exact* make and model of truck to ensure compatibility and avoid potential problems. Consider consulting a qualified mechanic or off-road specialist for advice and installation.
