Gympie Suspension

A proper 4WD suspension setup isn’t just about lifting your ride—it’s about control, comfort and capability. At Gympie Diesel & Dyno Centre, we install Tough Dog suspension systems that are engineered to deliver more than just clearance. They improve ride quality, handling and load-carrying strength across all terrains.


No matter how you drive—touring, towing, weekend trails or worksite loads—Tough Dog offers a tailored solution to match. With a huge range of spring and shock options, you can fine-tune every element to suit your vehicle and driving style. There’s also a full catalogue of accessories to dial in your suspension even further.


But here’s the catch: suspension upgrades can get messy fast. Between online advice and one-size-fits-all kits, it’s easy to end up with a setup that looks good but underperforms—especially under load. That’s why expert advice matters. Talk to us about your 4WD suspension needs and get it right from the start.

Get in touch with us on 07 5482 7877 to chat with a suspension specialist and get your 4WD set up right the first time.

Our Suspension Solutions

Enhancing your vehicle’s suspension performance is without question one of the best returns on investment you could make for your vehicle.


Our service covers every part of the suspension, including:


  • Control arms
  • Shocks
  • Struts
  • Ball joints
  • Tie rods & rod ends
  • Idler arms
  • Bushings
  • Pinions
  • Racks


We'll take a close look at every part of your suspension—because even one worn component can throw off your entire setup. From control arms to bushings and ball joints, everything gets checked for wear, alignment and performance.


The goal isn’t just to get your suspension working—it’s to get it working the way you want. Even a well-maintained system can feel rough, unbalanced or too soft for your driving needs. That’s where Tough Dog suspension comes in. It gives your vehicle a serious upgrade in handling, ride comfort and on-road safety.


We offer complete inspections, servicing and setup advice to help you get the most from your suspension—no guesswork, just smart upgrades that match how you drive.


Get in touch with us today at Gympie Diesel & Dyno Centre. We’re happy to go through some of the suspension options available for you.

When Off-Road Performance Matters to You

Most factory 4x4 and AWD suspension systems are built for smooth bitumen—not rugged bush tracks. They’re fine for city streets and the odd gravel road, but if you’re planning serious off-road adventures, your suspension needs a serious upgrade.


That’s where we come in—our team knows what holds up under pressure and what lets you down when the tracks get tough. We'll tweak your existing setup for better off-road handling or fit a full Tough Dog suspension system to take your ride to the next level.


You’ll notice the difference instantly—better grip, smoother response and a far more enjoyable drive across unpredictable terrain. Want to tackle steeper climbs and deeper ruts? We can increase your clearance too, opening up a whole new world of tracks and trails.

Prioritising Load Carrying & Ride Quality

From daily drivers to serious tourers, Tough Dog suspension delivers comfort and control—no matter the load. Whether you’re after a softer ride or firmer handling, we trust Tough Dog components to handle the job.


If you’re towing a trailer, hauling gear or loading up for a long trip, your suspension takes the hit first. That strain affects stability, braking and steering—and can turn a smooth drive into a handful. That’s why a proper suspension check matters.


We assess how your system holds up under pressure, identify weak points and offer clear options to boost your ride without breaking the bank. With quality parts and expert installation, you’ll drive away with confidence.
