Frequently Asked Questions About Freightliner Century 112/120 Shock Absorbers
What years and models are these shock absorbers compatible with?
These shock absorbers are specifically designed for Freightliner Century Class 112 and 120 models manufactured from 1996 to 2011. They fit both single and tandem axle configurations. Always verify your truck's exact model year and axle setup before ordering, as mounting points can vary between early and late production models.
How difficult is the installation process, and what tools do I need?
Installation typically takes 1-2 hours per axle for experienced mechanics. You'll need basic hand tools including socket wrenches (typically 3/4" and 7/8"), a torque wrench, and jack stands or a lift. The upper mounting bolt can be challenging to access on some models, so having a ratcheting box-end wrench helps. Professional installation is recommended if you're not comfortable working with suspension components under load.
What's the difference between OEM and aftermarket shock absorbers for my Century?
OEM shocks typically last 150,000-200,000 miles under normal conditions, while quality aftermarket options can match or exceed this lifespan at a lower cost. Key differences include warranty coverage (OEM usually 1 year, aftermarket varies), and nitrogen gas charging pressure. Popular aftermarket brands like Gabriel and Monroe offer heavy-duty options specifically valved for Century Class trucks that often provide better ride quality than original equipment.
How do I know when my shock absorbers need replacement?
Common signs include excessive cab bounce after hitting bumps, nose-diving during braking, uneven tire wear, or visible oil leaking from the shock body. A simple test is the "bounce test" - push down hard on each corner of the cab and release. If it bounces more than once before settling, the shocks are likely worn. Most Century drivers report needing replacement between 150,000-250,000 miles depending on load conditions and road quality.
Are heavy-duty or standard shock absorbers better for my application?
Heavy-duty shocks are recommended if you regularly haul maximum loads, drive on rough roads, or want extended service life. They feature larger piston diameters, increased oil capacity, and stronger mounting hardware. Standard shocks work well for highway driving with moderate loads. Heavy-duty options typically cost 20-30% more but can last up to 50% longer under demanding conditions.
