Frequently Asked Questions About Hino 238-338 Truck Front Axle Air Ride Kits

Will these air ride kits fit my specific Hino model year?

Our front axle air ride kits are designed to fit Hino 238 and 338 models from 2011 to present. However, there are slight variations between model years, particularly in the 2011-2012 models versus 2013 and newer. Before ordering, verify your truck's exact model year and check the product specifications or contact our support team with your VIN to ensure proper fitment.

How difficult is the installation process, and what tools are required?

Installation typically takes 4-6 hours for experienced mechanics and requires standard shop tools including air tools, torque wrenches, and jack stands. The kit comes with detailed instructions, but you'll need to safely support the truck frame, remove the existing leaf spring setup, and properly route air lines. Many customers recommend professional installation if you're not comfortable working with air systems or heavy truck suspensions. Budget approximately $400-600 for professional installation.

What's the actual ride improvement and load capacity with these kits?

These air ride kits provide significant ride quality improvement, reducing driver fatigue by up to 70% compared to stock leaf springs. The systems maintain a load capacity of 12,000-14,000 lbs per axle, matching or exceeding OEM specifications. You can adjust ride height within a 3-4 inch range and fine-tune the pressure for different load conditions, typically running 40-80 PSI depending on your application.

What maintenance is required, and how long do the air bags last?

Air bags typically last 100,000-150,000 miles with proper maintenance. Check air pressure weekly, inspect for leaks monthly, and drain moisture from the air system regularly. The rubber air springs should be cleaned with soap and water quarterly to prevent dry rot. Most failures occur from debris damage or improper installation rather than normal wear. Replacement air bags cost approximately $150-250 each when needed.

Do these kits require additional components beyond what's included?

The basic kit includes air bags, mounting brackets, and hardware, but you'll need an air management system if your truck doesn't already have one. This includes an air compressor, tank, gauges, and controls, which can add $300-800 to your total cost. Some customers also add height control valves for automatic leveling (additional $200-400). Verify what your specific truck already has before ordering to avoid duplicate purchases.
