Frequently Asked Questions About Freightliner FLC112 Leaf Springs, Hangers & Acc.
What years and models are these leaf springs compatible with?
Our Freightliner FLC112 leaf springs are designed to fit FLC112 models from 1985 through 2003. However, compatibility can vary based on your truck's specific configuration, including wheelbase, suspension type (air ride vs. spring), and whether you have a single or tandem axle setup. We recommend checking your VIN or calling our technical support team at 1-888-875-7787 with your truck's specifications to ensure proper fitment before ordering.
What's the difference between OEM and aftermarket leaf springs, and which should I choose?
OEM leaf springs are manufactured to original factory specifications and typically use the same steel grades and heat treatment processes as your truck's original equipment. Aftermarket options often provide comparable quality at a lower price point, with some offering improvements like shot-peened surfaces for better fatigue resistance or upgraded bushings. For daily commercial use, both options work well, but if you're hauling maximum loads regularly or operating in severe conditions, OEM or heavy-duty aftermarket springs may provide better longevity.
Can I install these leaf springs myself, or do I need special tools?
While leaf spring installation is possible for experienced mechanics, it requires specific tools including a heavy-duty jack or lift system, spring compressors, torque wrenches capable of 450-500 ft-lbs, and proper safety equipment. The job typically takes 4-6 hours per side and involves handling springs that can weigh 150-200 pounds each. Many customers find it more cost-effective and safer to have a commercial truck shop perform the installation, which usually runs $300-500 per axle in labor.
How do I know when my leaf springs need replacement?
Common signs include visible cracks or breaks in the spring leaves, excessive sagging (truck sits lower than normal), uneven tire wear, increased bounce or harsh ride quality, and separated or shifted leaves. You should also inspect for rust penetration beyond surface rust, worn or missing bushings, and bent or damaged spring hangers. If your truck leans to one side or you notice handling issues, immediate inspection is recommended as spring failure can be dangerous.
What's included in a complete leaf spring kit, and what else might I need?
A complete kit typically includes the leaf spring assembly with bushings pressed in, U-bolts, and mounting hardware. However, you may also need to purchase spring hangers, shackles, and pins separately depending on their condition. We recommend replacing worn hangers and shackles during spring replacement to ensure proper alignment and prevent premature wear. Anti-squeak pads or liners between leaves are also recommended and may need to be ordered separately depending on the kit you choose.
