The Honda Acty kei truck has earned a strong reputation for being a versatile and dependable workhorse. Compact in size yet big on capability, the Acty has served countless owners across Japan and abroad, handling everything from construction site duties to farm work and even daily commuting. Despite its practicality, one area where owners often seek improvements is the suspension system. Because of the truck’s utilitarian roots, its stock suspension is tuned primarily for light hauling and basic comfort, which doesn’t always translate well for modern use cases such as off-road adventures, lifted stances, or smoother road handling. Upgrading the suspension of an Acty truck not only enhances ride quality but also increases safety and performance.
In this detailed guide, we’ll explore the best suspension upgrades for a Honda Acty kei truck, whether you want better ride comfort, improved off-road durability, or a lifted stance that enhances versatility.
Why Suspension Upgrades Matter for the Honda Acty
The suspension system in any vehicle directly affects comfort, handling, and durability. For a kei truck like the Honda Acty, which often operates on rough terrain or carries loads, suspension plays an even greater role. The factory setup is reliable but basic, and decades of use can leave stock components tired or sagging.
Upgrading the suspension can:
-
Improve handling and stability when carrying heavy loads.
-
Offer a smoother ride on uneven or unpaved roads.
-
Increase ground clearance for off-road use.
-
Extend the life of tires and other mechanical components.
-
Provide a more enjoyable driving experience overall.
Owners who source Acty truck suspension components from trusted suppliers or browse options through Honda Acty Parts Online marketplaces often discover that they can customize their trucks to perform better than when they were new.
Common Suspension Weak Points in the Honda Acty
Before jumping into upgrades, it’s worth understanding the common weak points of the stock suspension:
-
Worn Shocks and Struts – The original dampers often lose efficiency after years of use, leading to bouncy or unstable handling.
-
Sagging Leaf Springs – The rear suspension relies on leaf springs, which can sag under consistent load or heavy use, reducing clearance and comfort.
-
Bushings and Mounts – Old rubber bushings harden and crack, creating vibrations and excessive play in the suspension.
-
Ride Height Limitations – The Acty’s stock ride height is modest, which limits its off-road potential or ability to clear obstacles.
Addressing these areas with modern upgrades can transform the driving dynamics of the truck.
Best Suspension Upgrades for Honda Acty Kei Trucks
1. Heavy-Duty Shock Absorbers
Upgrading the stock shocks is one of the most effective ways to improve both handling and comfort. Performance-oriented or heavy-duty shocks provide better damping, reducing body roll and improving stability when the truck is loaded.
Brands that specialize in compact Japanese vehicles or universal off-road shocks often offer compatible options. For drivers who frequently carry cargo, stiffer shocks prevent excessive squat, while owners who use their Acty for daily commuting can select softer shocks for a more comfortable ride.
2. Lift Kits and Spacer Kits
A popular modification for Acty trucks, lift kits give the vehicle additional ground clearance. This is especially useful for off-road enthusiasts or those who regularly drive on uneven rural roads.
Lift kits typically come in two forms:
-
Coil Spring Spacers – Installed above the front struts to raise the vehicle slightly without major modifications.
-
Leaf Spring Shackles or Blocks – Installed in the rear to increase clearance and reduce sag.
A mild lift of 1–2 inches is usually enough to accommodate larger tires while maintaining drivability. Extreme lifts are possible but may require additional modifications to steering and driveline angles.
3. Upgraded Leaf Springs
The rear suspension of the Acty relies on leaf springs, which are durable but prone to sagging after years of hauling. Replacing them with upgraded or heavy-duty versions restores ride height and increases load-carrying capacity.
For owners using their kei trucks as utility vehicles, heavy-duty leaf springs ensure the truck doesn’t bottom out under weight. Meanwhile, enthusiasts looking for off-road performance can opt for aftermarket springs that balance stiffness with articulation.
4. Coilover Conversions
While not as common, some Acty owners install coilover kits to achieve maximum adjustability. Coilovers allow precise control of ride height, damping stiffness, and handling characteristics.
This is particularly attractive for owners who want to fine-tune their trucks for specific uses, such as lifted off-road setups or lowered urban builds. Though more expensive than basic upgrades, coilovers offer unmatched versatility and performance.
5. Polyurethane Bushings
The small rubber bushings that connect suspension components wear down over time, causing vague steering and excess vibration. Replacing these with polyurethane bushings sharpens handling, increases durability, and provides a more direct road feel.
Though polyurethane bushings can transmit slightly more vibration than rubber, they are ideal for owners seeking a sportier or more controlled drive.
6. Stabilizer Bars and Sway Bars
Some Honda Acty models have minimal anti-roll bar support, leading to noticeable body roll during turns. Adding or upgrading sway bars significantly improves stability, especially when driving on highways or winding roads.
For kei truck owners who spend more time in urban areas than on dirt trails, this modification makes the Acty feel more planted and responsive.
Balancing Comfort and Performance
When upgrading the suspension of an Acty truck, it’s important to balance comfort with functionality. For example, stiff heavy-duty shocks may be great for hauling but can create a harsh ride for daily commuting. Similarly, large lift kits improve off-road ability but may affect fuel economy and steering precision.
The best strategy is to first define the truck’s primary role:
-
Workhorse Use – Heavy-duty leaf springs and shocks to handle loads.
-
Off-Road Build – Lift kit, upgraded shocks, and reinforced bushings for rugged terrain.
-
Daily Driver – Comfort-oriented shocks and stabilizer bars for smoother handling.
By tailoring the suspension setup to your specific needs, you ensure that the upgrades actually enhance the truck’s usability.
Installation Considerations
Suspension upgrades can be tackled by experienced DIY enthusiasts, but professional installation is often recommended. Kei trucks have compact underpinnings, and improper installation of lift kits or shocks can lead to misaligned steering or uneven tire wear.
Key considerations during installation include:
-
Wheel alignment after replacing suspension components.
-
Ensuring proper torque specifications on bolts and fasteners.
-
Checking for clearance issues when lifting the vehicle.
-
Inspecting related components such as brake lines and steering arms.
A well-executed installation ensures that suspension upgrades perform as intended and last longer.
Cost of Suspension Upgrades
One of the benefits of owning a kei truck like the Acty is that upgrades are generally affordable compared to larger vehicles. Basic shock replacements might cost under a few hundred dollars, while lift kits and upgraded leaf springs range higher depending on brand and complexity. Coilover conversions, being more advanced, sit at the top of the pricing scale but offer the most flexibility.
Browsing through Honda Acty spares suppliers or Honda mini truck upgrade forums can reveal budget-friendly options, while specialty sites that sell Honda Acty truck suspension parts often stock high-quality kits designed specifically for kei vehicles.
Real-World Benefits of Upgrading
Owners who have invested in suspension upgrades for their Acty trucks often report noticeable improvements in both performance and practicality. Some key benefits include:
-
Better Ride Quality – Reduced bouncing and smoother handling on rough roads.
-
Improved Safety – Enhanced stability when cornering or carrying loads.
-
Extended Vehicle Life – Less stress on tires, axles, and drivetrain components.
-
Increased Versatility – Ability to handle off-road trails, farms, or construction sites with ease.
The Acty is already a versatile vehicle, but upgraded suspension makes it even more adaptable to modern needs.
