Frequently Asked Questions About Mack CX Truck Shock Absorbers
Will these shock absorbers fit my specific Mack CX model year?
Our Mack CX shock absorbers are designed to fit CX613 models from 1998-2007. However, there can be variations based on your truck's suspension configuration (air ride vs. spring suspension) and whether you have a day cab or sleeper. We recommend checking your current shock's part number or calling our tech support at 1-888-875-2425 with your VIN to ensure proper fitment.
What's the difference between OEM and aftermarket shock absorbers for my Mack CX?
OEM shocks are built to original factory specifications and typically last 50,000-75,000 miles under normal conditions. Aftermarket options like Gabriel or Monroe often feature upgraded valving and heavy-duty construction that can extend life to 100,000+ miles. Many aftermarket shocks also offer better dampening control for loaded conditions. The main trade-off is price - aftermarket shocks usually cost 30-40% less than OEM.
Can I install these shock absorbers myself, or do I need special tools?
Front shock replacement on a Mack CX is generally straightforward and requires basic hand tools - socket set, wrenches, and jack stands. Rear shocks can be more challenging due to limited access and may require removing wheels. You'll need a torque wrench to properly tighten mounting bolts (typically 85-95 ft-lbs for upper mounts, 125-140 ft-lbs for lower). Allow 45-60 minutes per shock for DIY installation. Always replace shocks in pairs per axle.
How do I know when my Mack CX shocks need replacement?
Common signs include excessive bouncing after hitting bumps, nose-diving during hard braking, uneven tire wear, or visible oil leaking from the shock body. You can also perform a bounce test - push down hard on each corner of the truck and release. If it bounces more than once, the shocks are worn. Most drivers report needing replacement between 75,000-150,000 miles depending on load conditions and road quality.
Do you offer heavy-duty or specialized shocks for severe service applications?
Yes, we carry several heavy-duty options for Mack CX trucks used in construction, logging, or heavy hauling. These feature larger piston diameters, reinforced mounting eyes, and nitrogen-charged designs for better heat dissipation. Brands like Bilstein and Gabriel FleetLine offer severe-service models specifically engineered for trucks that frequently operate at maximum GVWR or on rough terrain. These typically cost 20-30% more but can double the service life under harsh conditions.
