Heavy haul work pushes your truck to the limit. Every load, every stretch of tough Aussie road, and every stop puts pressure on your suspension and steering.
If these systems aren’t up to the job, you’ll feel it in the handling, in your tyres, and in your maintenance bills. Worn or under-spec parts can mean more fatigue for the driver, uneven wear, and expensive repairs.
The right suspension and steering upgrades keep your truck stable, comfortable, and ready for the long haul, protecting your gear, your load, and your bottom line.
Why Suspension & Steering Matter More in Heavy Hauling
When you’re running heavy, your suspension isn’t just about comfort, it’s about control. Good suspension:
-
Maintains tyre contact with the road for better braking and stability.
-
Absorbs harsh road impacts, protecting both your cargo and your chassis.
-
Reduces driver fatigue on long hauls, improving focus and safety.
-
Minimises the wear and tear on other critical systems.
Without a strong suspension and steering system, your truck works harder than it should, and that’s when breakdowns happen.
Key Upgrades for a Smoother, Safer Haul
Modern suspension technology has come a long way, and the products in our Heavy Haul Heroes lineup are designed to meet the demands of serious hauling.
Air Springs & Airbags
Air systems are the heart of ride quality under load.
Shock Absorbers
Shocks aren’t just for comfort, they control bounce, reduce vibration, and protect steering components.
From Hendrickson’s proven Shock Absorber (HN98583010) to Powerdown’s range for specific truck models like Kenworth, Mack, and Western Star, these components are engineered for heavy-duty damping.
The BPW SHOCK ABSORBER 475-800MM (BPW0237021802) ensures stability on trailers as well. A heavy-duty component designed to keep loads steady and maintain good tyre contact with the road, particularly critical during braking and cornering under load.
Steering & Linkage Components
Precision steering under load comes from quality linkages and joints. STEMCO’s QWIKKIT KING PIN KIT FG931 FG941 (STMKG931R) and QWIKTIE TIE ROD ASSEMBLY - FL941 (STMQT108SB) keep steering tight, responsive, and dependable.
The QWIKTIE® tie rod assembly is engineered for long-term reliability under demanding road conditions, featuring a patented design for safer installation, a high-strength powder-coated cross tube for durability, and finer threads for precise adjustment and smoother handling.
Its improved clamping system ensures a secure fit, while colour-coded ends make identification quick and simple, helping fleets reduce downtime, streamline inventory, and lower total cost of ownership.
Bush Kits
Bushings may be small, but they prevent play and wear in suspension arms.
MAXUS Products offer solutions like the PIVOT BUSH KIT SUIT AIRMAX SUSPENSIONS (SP1500K) and CS10.5 PIVOT BUSH REPAIR KIT (AMA11225N1522RK) to maintain performance over the long haul.
Braking & Rotor Components
For trailers with integrated braking in the suspension system, the Hendrickson MAXX22T ROTOR KIT (HN98815027) ensures safe, consistent stopping power, essential for control on steep descents.
How These Upgrades Pay Off
Think of your suspension and steering as the buffer between your load and the road. Upgrading them does more than improve comfort, it:
-
Reduces repair costs by preventing damage to axles, frames, and driveline parts.
-
Protects your tyres by maintaining proper contact and alignment.
-
Improves resale value with a smoother, more responsive truck.
-
Boosts safety by improving stability during emergency braking or evasive manoeuvres.
Suspension and steering are key to every heavy haul job. With quality gear from Hendrickson, Powerdown, MAXUS, BPW, and STEMCO, you can keep your truck riding smooth, handling well, and ready for the long haul. A smoother ride is not just about comfort, it is an investment in safety, efficiency, and keeping your operation moving.
