Freightliner Columbia 112/120 Leaf Springs-Hanger

Frequently Asked Questions About Freightliner Columbia 112/120 Leaf Springs & Hangers

What years and models are these leaf springs compatible with?

These leaf springs and hangers are specifically designed for Freightliner Columbia 112 and 120 models manufactured between 2000-2015. However, compatibility can vary based on your truck's configuration, including wheelbase length and suspension type. We recommend checking your VIN or contacting our support team with your specific model year and configuration to ensure proper fitment before ordering.

What's the difference between OEM and aftermarket leaf springs for my Columbia?

OEM leaf springs match factory specifications exactly and typically cost 30-40% more than aftermarket options. Quality aftermarket springs use similar steel grades and manufacturing processes but may have slight variations in arc height or load ratings. Most aftermarket springs we carry are rated for the same weight capacity as OEM parts and include proper bushings and hardware. The main differences you'll notice are in warranty coverage (aftermarket usually 1-2 years vs. OEM 3 years) and minor variations in ride height.

Can I install these leaf springs myself or do I need special tools?

While leaf spring replacement is possible for experienced DIY mechanics, it requires specific tools including a heavy-duty jack, jack stands rated for commercial trucks, spring compressors, and torque wrenches capable of 450-500 ft-lbs. The job typically takes 4-6 hours per side. Safety is critical - improperly compressed springs can cause serious injury. Most customers opt for professional installation, which runs $300-500 per axle at most truck shops.

How do I know when my leaf springs need replacement?

Common signs include sagging ride height (measure from frame to ground and compare sides), visible cracks or breaks in spring leaves, separated or shifted leaves, worn-out bushings causing clunking noises, and uneven tire wear. If your Columbia leans to one side when unloaded or bottoms out frequently, it's time for inspection. A 2-3 inch sag from original ride height typically indicates replacement is needed.

What's included with the leaf spring assemblies and what else might I need?

Most complete leaf spring assemblies include the spring pack, center bolt, and clips. However, you'll typically need to order bushings, shackle pins, U-bolts, and hangers separately unless purchasing a complete kit. We recommend replacing hangers and bushings at the same time as springs - old hangers often crack during removal and worn bushings will cause premature spring wear. Budget an additional $150-300 for these components per axle.
