The Subaru Sambar Kei Truck is a popular lightweight mini truck known for its versatility, reliability, and compact size. Initially introduced in the 1960s as a utility vehicle in Japan, the Sambar has since gained global recognition as an excellent workhorse for small businesses, farms, and recreational purposes. While it performs well in stock form, many enthusiasts modify their Subaru Sambar to suit specific needs.
This article explores the best modifications for Subaru Sambar Kei Trucks, focusing on upgrades that enhance performance, comfort, aesthetics, and off-road capability. Whether you use your Sambar for utility purposes or off-road adventures, these modifications can take your mini truck to the next level.
1. Performance Upgrades
Even though the Subaru Sambar Kei Truck isn’t a performance vehicle by design, several modifications can improve its power, handling, and efficiency. Below are some essential performance upgrades:
A. Air Intake and Exhaust System
Improving the airflow into the engine enhances efficiency and boosts power. Replacing the stock air intake with a high-performance cold air intake improves throttle response and engine sound. In addition, an aftermarket exhaust system reduces back pressure, allowing the engine to breathe better.
Recommended Parts:
- K&N or AEM cold air intakes
- Cat-back exhaust system for improved engine note and performance
These simple changes not only add a few horsepower but also enhance fuel efficiency, making your Sambar more enjoyable to drive.
B. ECU Tuning
ECU tuning or remapping adjusts the factory engine settings to optimize performance. With proper tuning, the Subaru Sambar can achieve better throttle response and slightly increased top-end power. Some tuners specialize in reprogramming the electronic control unit (ECU) for mini trucks like the Sambar.
C. Turbocharger Installation
A more ambitious modification is installing a small turbocharger. While challenging, adding a turbo boosts engine output without compromising fuel efficiency. Subaru’s 660cc engine can comfortably handle a modest turbo, significantly improving the Kei truck’s highway performance.
2. Off-Road Modifications
Many Subaru Sambar Kei Truck owners modify their vehicles for off-road use, especially for farms, campgrounds, and outdoor adventures. These upgrades enhance the truck’s ability to navigate uneven terrains.
A. Lift Kits
A lift kit raises the vehicle’s height, providing better ground clearance for off-road driving. Lift kits range from 1.5 to 3 inches and allow you to install larger tires, further improving off-road performance.
Popular Lift Kit Brands:
- Axxis Offroad
- SuperMini Trucks Lift Kits
B. Off-Road Tires
Standard road tires are not ideal for rough terrain. Switching to all-terrain or mud tires gives your Sambar better grip on dirt, mud, and gravel roads. Look for tires with aggressive tread patterns suitable for off-road adventures.
Recommended Tires:
- Yokohama Geolandar A/T
- BFGoodrich Mud-Terrain tires
C. Skid Plates and Underbody Protection
Adding skid plates protects the truck’s undercarriage from rocks and debris when driving on rugged terrain. Essential areas to cover include the engine, transmission, and fuel tank. This modification ensures your Sambar remains functional even after tough trails.
3. Interior Comfort and Convenience Upgrades
Although functional, the interior of the Subaru Sambar Kei Truck is relatively simple. Several modifications can enhance comfort, convenience, and practicality for both everyday use and long drives.
A. Seat Upgrades
The stock seats are designed for utility but may lack long-term comfort. Replacing them with ergonomic seats with better padding, lumbar support, and adjustable headrests can drastically improve driving comfort.
B. Soundproofing
Kei trucks like the Sambar are known for road noise due to thin body panels. Installing sound-deadening materials like Dynamat or Noico reduces noise and vibration inside the cabin, resulting in a quieter and more comfortable ride.
C. Infotainment System
Updating the stock radio to a modern infotainment system with Bluetooth, GPS, and touchscreen controls adds convenience, especially if you use the truck for long journeys. Some owners also install backup cameras for improved rear visibility, making parking easier.
Recommended Systems:
- Pioneer AVH-Series head units
- Android Auto and Apple CarPlay-compatible stereos
4. Aesthetic and Exterior Modifications
Many Subaru Sambar Kei Truck owners enjoy customizing their vehicles to make them more visually appealing. These aesthetic upgrades allow you to express your style and improve the truck’s exterior appearance.
A. Custom Paint Jobs and Wraps
Changing the paint color or applying a vinyl wrap gives the Sambar a fresh, unique look. Owners often go for retro themes or off-road-inspired designs. Wraps also protect the original paint and are easy to change if you want a new look in the future.
B. LED Lighting Upgrades
LED headlights, fog lights, and auxiliary light bars improve visibility during night driving and off-road adventures. These lights consume less power than halogen bulbs and last longer, making them an ideal upgrade.
Recommended Lighting Brands:
- Rigid Industries light bars
- Philips or Osram LED headlight bulbs
C. Roof Racks and Utility Accessories
Roof racks increase cargo-carrying capacity, making them useful for hauling equipment or luggage. You can also add accessories like a roof tent or bike rack to enhance the vehicle’s utility for outdoor adventures.
5. Suspension and Handling Upgrades
Improving the suspension system ensures a smoother ride and better handling, especially for off-road enthusiasts or those who carry heavy loads regularly. Below are some key upgrades to consider.
A. Upgraded Shocks and Struts
Replacing the factory shocks with performance shocks enhances the vehicle’s ability to handle rough roads. Adjustable shocks allow you to tune the suspension according to the load or terrain you’re tackling.
B. Sway Bars and Stabilizers
Adding sway bars reduces body roll, improving cornering stability on the road. This modification is particularly useful if you frequently drive on winding roads or highways with a loaded cargo bed.
C. Wheel Spacers
Wheel spacers push the wheels further out from the vehicle’s body, giving the Sambar a wider stance. This improves stability, especially on uneven ground, and gives the truck a more aggressive look.
6. Utility and Cargo Management
Since the Subaru Sambar Kei Truck is often used for transporting goods, several modifications can enhance its cargo-handling capabilities.
A. Bed Liners and Covers
Adding a bed liner protects the truck bed from scratches and dents caused by heavy loads. Hard or soft bed covers, on the other hand, secure your cargo from weather elements and theft.
Types of Bed Covers:
- Hard tonneau covers for security
- Soft roll-up covers for flexibility
B. Toolboxes and Storage Solutions
Installing a toolbox or under-bed storage compartments ensures you can carry tools and essential gear safely and neatly. This modification is especially useful for tradespeople and farm owners.
7. Braking System Upgrades
Improving the braking system is essential, especially if you plan to carry heavy loads or drive on challenging terrains.
A. Performance Brake Pads and Rotors
Upgrading to performance brake pads provides better stopping power and reduces brake fade. Slotted or drilled rotors improve cooling, making them ideal for off-road or high-load situations.
B. Stainless Steel Brake Lines
Replacing the stock rubber brake lines with stainless steel ones ensures consistent braking performance. Stainless steel lines reduce expansion, resulting in a firmer brake pedal feel.
Conclusion
The Subaru Sambar Kei Truck is a versatile vehicle with vast modification potential. Whether you want to boost performance, improve off-road capability, enhance interior comfort, or make it visually appealing, there are numerous upgrades available to suit your needs. From practical modifications like lift kits and bed covers to performance enhancements like air intake systems and turbochargers, these upgrades can turn your Sambar into a highly functional and personalized mini truck.
By investing in the right modifications, you can optimize your Subaru Sambar Kei Truck to excel in various environments—whether it’s a worksite, farm, or the great outdoors.
