Enhancing Ride Quality and Performance with OBS Trucks Suspension Upgrades

Older Body Style (OBS) trucks have a loyal following among truck enthusiasts. These trucks, produced mainly in the late 1980s through the late 1990s, are known for their rugged design and durability. Yet, many owners find that the original suspension systems can feel outdated or less comfortable compared to modern trucks. Upgrading the suspension on an OBS truck can dramatically improve ride quality, handling, and overall performance. This post explores practical suspension upgrade options that can transform your OBS truck into a smoother, more capable vehicle.

Why Upgrade the Suspension on an OBS Truck?

The suspension system plays a crucial role in how a truck handles road conditions, carries loads, and absorbs shocks. Many OBS trucks came with leaf springs and basic shock absorbers that were designed for durability but not for comfort or performance. Over time, these components wear out, leading to:

• Harsh rides on rough roads

• Poor handling and body roll during turns

• Reduced load-carrying stability

• Increased wear on tires and other parts

  
  

Upgrading the suspension addresses these issues by improving shock absorption, reducing body sway, and enhancing control. This means a safer, more comfortable ride whether you’re driving daily or hauling heavy loads.

Common Suspension Upgrades for OBS Trucks

Several suspension upgrade options suit different budgets and goals. Here are some of the most effective upgrades for OBS trucks:

1. Replacing Leaf Springs with Multi-Leaf or Helper Springs

Many OBS trucks use leaf springs in the rear suspension. Over time, these springs can sag or lose their tension. Upgrading to multi-leaf springs or adding helper springs can restore ride height and improve load capacity. Helper springs provide extra support when carrying heavy loads without sacrificing ride comfort when unloaded.

2. Installing Coilover Shocks

Coilover shocks combine a coil spring and shock absorber into one unit. They offer better damping control and allow for adjustable ride height and stiffness. Coilovers improve handling by reducing body roll and providing a smoother ride on uneven terrain. This upgrade is popular among those who want a sportier feel without sacrificing durability.

3. Upgrading to Heavy-Duty Shocks

Replacing factory shocks with heavy-duty or performance shocks can significantly improve ride quality. These shocks are designed to handle rougher conditions and provide better rebound control. Brands like Bilstein and Rancho offer shocks specifically tuned for OBS trucks, balancing comfort and off-road capability.

4. Adding Sway Bars or Upgrading Existing Ones

Sway bars reduce body roll during cornering, improving stability and control. Many OBS trucks have basic sway bars that can be upgraded to thicker or adjustable versions. This upgrade is especially useful if you tow trailers or carry heavy loads, as it keeps the truck more level and responsive.

5. Installing Air Suspension Kits

For those seeking maximum adjustability, air suspension kits allow you to change ride height and stiffness on the fly. This is ideal for trucks used both for daily driving and heavy hauling. Air suspension can improve comfort and protect the truck’s frame and cargo from harsh impacts.

How Suspension Upgrades Improve Performance

Upgrading your OBS truck’s suspension does more than just soften the ride. It enhances overall performance in several ways:

• Better Handling: Reduced body roll and improved shock absorption make steering more precise and predictable.

• Increased Load Capacity: Stronger springs and shocks support heavier loads without sagging or bottoming out.

• Improved Tire Life: More even weight distribution and less bouncing reduce tire wear.

• Enhanced Safety: Better control means shorter stopping distances and less risk of rollover.

• Customizable Ride: Adjustable coilovers or air suspension let you tailor the ride to your needs.

  
  

Practical Tips for Choosing Suspension Upgrades

When selecting suspension upgrades for your OBS truck, consider these factors:

• Intended Use: Daily driving, off-roading, towing, or hauling all require different setups.

• Budget: Some upgrades like heavy-duty shocks are affordable, while coilovers and air suspension kits cost more.

• Compatibility: Ensure parts are designed for your truck’s make and model to avoid fitment issues.

• Installation: Some upgrades require professional installation, while others can be DIY projects with the right tools.

• Ride Preference: Decide if you want a softer ride or a firmer, sportier feel.

  
  

Maintaining Your Upgraded Suspension

Upgraded suspension components still need regular maintenance to perform well. Check for:

• Worn bushings or mounts

• Leaking shocks or air bags

• Proper alignment and tire balance

• Rust or corrosion on springs and hardware

  
  

Routine inspections help catch problems early and extend the life of your upgrades.
