If you tow, haul heavy loads, or take your vehicle off-road, you’ve probably felt the effects of sagging suspension. Maybe your truck squats under the weight of a trailer, or your RV sways a little too much on the highway. That’s where suspension load support comes in.
But what exactly is suspension load support, and how does it work? In this guide, we’ll break it down, explain your options, and show you how SumoSprings® from SuperSprings International can transform your ride.
Understanding Suspension Load Support
At its core, suspension load support is all about helping your vehicle handle weight more effectively. When you add extra cargo, tow a trailer, or carry passengers, your factory suspension has to work harder to keep everything stable. Without support, you might experience:
- Rear-end sag – Your vehicle’s rear dips lower than the front.
- Unstable handling – You feel excessive sway, body roll, or bouncing.
- Uneven tire wear – The added strain can cause premature wear on tires and suspension components.
Load support solutions help distribute weight more evenly, reduce stress on your suspension, and improve handling.
Types of Suspension Load Support
There are a few ways to enhance your suspension’s ability to handle weight:
1. Airbags
Airbags use compressed air to lift the vehicle’s rear and prevent sagging. They’re adjustable, meaning you can add or release air based on your load. The downside? Airbags require ongoing maintenance, can leak, and often need a compressor to function properly.
2. Add-a-Leaf Kits
These kits add an extra leaf spring to stiffen the rear suspension. While effective, they can make your ride feel harsher when you’re not carrying a load.
3. Helper Springs
Helper springs engage when extra weight is added, providing additional support only when needed. This keeps ride quality smooth when unloaded.
4. Microcellular Polyurethane Springs (SumoSprings®)
Unlike airbags, SumoSprings don’t require compressors, airlines, or maintenance. These durable, closed-cell foam springs provide progressive load support—compressing under pressure and offering a smoother ride while reducing sag, sway, and bounce.
