Frequently Asked Questions About International LT Leaf Springs, Hangers & Acc.
Will these leaf springs fit my specific International LT model year?
Our International LT leaf springs are designed to fit 2017 and newer International LT models. However, there can be variations based on your truck's configuration, including wheelbase, suspension type (air ride vs. spring), and whether you have a day cab or sleeper. Before ordering, check your VIN plate for the exact suspension code, or contact our support team with your VIN number and we can verify the correct part for your specific truck.
What's the difference between OEM and aftermarket leaf springs for my International LT?
OEM leaf springs are manufactured to exact factory specifications and typically come with a higher price point but guaranteed fit. Our aftermarket options are built to meet or exceed OEM standards, often using improved steel alloys and enhanced coating processes for better corrosion resistance. Most aftermarket springs we carry feature e-coating or powder coating for extended life, and many customers report equal or better performance compared to factory springs at a more competitive price point.
Do I need special tools or professional installation for leaf spring replacement?
Replacing leaf springs on an International LT requires heavy-duty equipment including a truck jack rated for commercial vehicles, heavy-duty jack stands, spring compressors, and torque wrenches capable of 450-500 ft-lbs. The job typically takes 4-6 hours per side for experienced mechanics. Due to safety concerns and the need for proper torque specifications, we strongly recommend professional installation. Many customers have reported that improper installation can lead to premature wear or dangerous driving conditions.
How do I know when my leaf springs need replacement?
Common signs include visible cracks or breaks in the leaves, sagging on one side causing uneven ride height, excessive bouncing or harsh ride quality, and abnormal tire wear patterns. On International LT trucks, also check for worn or damaged spring eye bushings, broken center bolts, or shifted leaf packs. If your truck sits more than 2 inches lower on one side when unloaded, it's time for inspection. Regular drivers often notice decreased stability when turning or increased body roll as early warning signs.
What hangers and accessories should I replace along with my leaf springs?
When replacing leaf springs on your International LT, inspect and consider replacing spring hangers, shackles, U-bolts, and bushings. These components wear together, and reusing old hardware with new springs can cause premature failure. Most technicians recommend replacing U-bolts every time as they stretch during use and lose clamping force. Spring eye bushings and shackle bushings should be replaced if they show any cracking, excessive wear, or play. Our complete kits include new grade 8 hardware to ensure proper installation and longevity.
