The BOSCH LA85 Air Spring Helper Suspension Kit is a popular aftermarket upgrade for Sprinter vans with the 2500 axle. This kit is designed to improve the vehicle's handling and ride quality by supplementing the standard suspension system with air springs. Here are some pros and cons to consider before making a purchase:

1. Enhanced Ride Comfort: Air springs provide a more level ride, especially when the van is carrying a heavy load. They absorb road irregularities better than conventional springs, resulting in a smoother ride.

2. Improved Handling: The air springs help maintain the van's level position during cornering and braking, resulting in improved handling. This is particularly beneficial when carrying heavy loads or towing a trailer.

3. Better Payload Capacity: By providing additional support, the air springs allow for a higher payload capacity. This can be a significant advantage for businesses that rely on their Sprinter van for transporting goods.

4. Adjustability: The BOSCH LA85 kit allows for adjustability, enabling users to customize the ride height and suspension stiffness to their preferences.

1. Cost: Air suspension kits can be expensive compared to conventional springs. The BOSCH LA85 kit is no exception, with a significant investment required upfront.

2. Complexity: Air suspension systems are more complex than conventional springs. Installing the kit requires a higher level of technical expertise and additional maintenance.

3. Repair and Maintenance: Air suspension components can fail, and repairing them can be costly and time-consuming. Regular maintenance is necessary to ensure the system functions properly and efficiently.

4. Noise: Some users have reported increased noise from the air springs, which can be a source of annoyance.

The BOSCH LA85 Air Spring Helper Suspension Kit offers several benefits, including enhanced ride comfort, improved handling, better payload capacity, and adjustability. However, its cost, complexity, and the need for regular maintenance are significant drawbacks.

Ultimately, the decision to purchase this kit depends on your personal needs and preferences. If you frequently carry heavy loads or require improved handling, the benefits may outweigh the costs. However, if you're looking for a more budget-friendly option or prefer a simpler suspension system, conventional springs may be a better choice.

If you decide that the BOSCH LA85 Air Spring Helper Suspension Kit is the right choice for you, make sure to install it professionally to ensure optimal performance and minimize the risk of issues. Regular maintenance is also essential to keep the system functioning properly and efficiently. If you're unsure about the installation process or have any questions, consult a qualified mechanic for advice.
