Frequently Asked Questions About Kenworth T880 Shock Absorbers

Will these shock absorbers fit my specific T880 model year and configuration?

Most aftermarket shock absorbers for the T880 are designed to fit model years 2013-present, but compatibility can vary based on your truck's suspension configuration (air ride vs. spring), axle setup (single or tandem), and whether you have a vocational or highway setup. Before ordering, check the product specifications against your VIN or contact our technical support team with your truck's model year, suspension type, and axle configuration for a guaranteed fit.

How difficult is the installation, and what tools will I need?

Installation typically takes 2-3 hours per axle for experienced mechanics. You'll need basic hand tools including socket wrenches (typically 18mm-24mm), a torque wrench, and possibly a spring compressor for certain applications. The upper and lower mounting bolts can be challenging to access, especially on trucks with auxiliary equipment. Many customers report needing to support the axle with a jack during installation. Professional installation is recommended if you're not comfortable working with heavy suspension components.

What's the difference between OEM and aftermarket shock absorbers for my T880?

OEM shocks typically use a standard valving designed for general-purpose use, while quality aftermarket options often provide application-specific valving for vocational trucks, heavy hauling, or highway use. Aftermarket shocks from brands like Gabriel, Monroe, and Bilstein may offer better heat dissipation, larger pistons, and more durable seals compared to standard OEM units. The main trade-off is that OEM shocks guarantee exact fit and maintain warranty compliance if that's a concern.

How long should T880 shock absorbers last, and what are signs they need replacement?

Under normal vocational use, expect 50,000-75,000 miles from quality shocks, though severe-duty applications like construction or logging may see 30,000-40,000 miles. Replace shocks if you notice excessive bouncing after hitting bumps, nose-diving during braking, uneven tire wear, visible oil leaks on the shock body, or if the shock can be easily compressed by hand. Operating with worn shocks accelerates tire wear and can damage other suspension components.

Do I need to replace shocks in pairs, and should I upgrade springs at the same time?

Yes, always replace shocks in axle pairs (both fronts or both rears together) to maintain balanced handling and prevent premature wear on the new shock. While you don't necessarily need to replace springs simultaneously, it's worth inspecting them during shock replacement. If springs show signs of sagging, cracking, or if your truck sits lower than specification, replacing them together saves labor costs and ensures optimal suspension performance.
