JA Easy Lock-Up Kit:
Factory transmissions may not always be the optimal choice for situations that demand additional performance. In some tougher driving situations, the switching between lockup and unlock modes can quickly result in excessive heat buildup, hindering the engine’s full power potential when you need it most.
Our Easy Lock-Up Kit is incredibly simple—no wires, just software. This straightforward implementation into your vehicle allows you to lock the converter for both low-speed and high-speed scenarios, ensuring that your transmission operates efficiently under a variety of conditions.
- Optimised Performance: By allowing you to lock the converter at the right times, the Easy Lock-Up Kit ensures that your transmission is always delivering optimal performance. This means better power transfer and more responsive driving.
- Reduced Transmission Temperature: Excessive heat is a constant battle in high-performance driving, but our lock-up kit helps alleviate this issue. By locking the converter when needed, it reduces the heat buildup that can occur from constant switching, thereby protecting your transmission and extending its lifespan.
- Simple Integration: The software-based solution means that installing the Easy Lock-Up Kit is straightforward, with no complicated wiring involved. This ensures a seamless integration into your vehicle’s existing system, allowing you to enjoy the benefits without any hassel.

JA 4-Inch Exhaust System:
Our 4 inch exhaust system not only sounds cool, but delivers an impressive performance that’s sure to turn heads. The larger diameter allows for increased airflow out of your engine, effectively reducing back-pressure. This reduction in back-pressure is key to unlocking more power from your engine, leading to noticeable improvements in various aspects of your driving experience, including:
- Increased Airflow: The JA 4-Inch Exhaust System ensures that exhaust gases exit the engine more efficiently. This enhanced airflow reduces engine strain and promotes smoother operation.
- Improved Acceleration: With reduced back-pressure, your engine can breathe more easily. This translates to better throttle response and quicker acceleration, giving you a more responsive driving experience.
- Enhanced Towing Capacity: The increased power and efficiency from the improved exhaust flow mean your vehicle can handle heavier loads with ease. Whether you’re towing a trailer or hauling equipment, you’ll notice a significant improvement in your vehicle’s capability.
- Enjoyable Driving Experience: The improved airflow, acceleration, and towing capacity makes for a more enjoyable driving experience overall. Plus, the robust sound of the 4-inch exhaust adds a thrilling auditory element that just makes driving feel more powerful.
- Durable and Reliable: The JA 4-Inch Exhaust System is designed to withstand the rigors of off-road driving and harsh conditions, ensuring long-lasting performance and reliability.
Just Autos Air box & Snorkel
Factory airboxes can quickly become blocked up and experience dusting issues, which ultimately negatively influences engine performance. These issues can lead to premature engine and turbo wear, reducing the lifespan and efficiency of your vehicle. Our JA Airbox, however, is engineered to enhance airflow efficiency and filtration, ensuring that your engine receives clean, unrestricted air at all times.
Our Airboxes are also paired with a snorkel, offering additional protection during water crossings. The snorkel ensures that your engine remains safe and dry, preventing water from entering and causing serious damage.
- Improved Airflow Efficiency: The JA Airbox is designed to maximise airflow to your engine, by upgrading the standard smaller factory air filter to the larger VDJ79 Series air filter. Enhanced airflow means your engine can breathe more easily, leading to better fuel combustion and increased power output.
- Superior Filtration: Dust and debris are common challenges for any off-road enthusiast. Our airbox provides superior filtration, preventing these contaminants from entering your engine and causing damage. This helps maintain optimal engine health and performance over the long term.
- Preventing Engine and Turbo Wear: By ensuring clean and efficient airflow, the JA Airbox helps avoid the premature wear and tear often caused by dust and debris. This means a longer lifespan for your engine and turbo, with less need for costly repairs or replacements.
- Quality and Reliability: We have partnered with top-tier aftermarket and automotive brands to deliver quality airboxes that meet the highest standards.
