Frequently Asked Questions About Peterbilt 389 Glider Shock Absorbers
Will these shock absorbers fit my specific Peterbilt 389 glider kit model year?
Our Peterbilt 389 glider shock absorbers are designed to fit all 389 glider models from 2007 to present. However, there can be variations depending on your specific suspension configuration (air ride vs. spring suspension) and whether you have a standard or extended cab. We recommend checking your current shock part numbers or calling our tech support at 1-888-875-2425 with your VIN to ensure proper fitment.
What's the difference between standard and heavy-duty shock absorbers for my 389 glider?
Standard shocks are suitable for typical highway driving and loads under 80,000 lbs GVW. Heavy-duty shocks feature larger bore diameters, reinforced mounting points, and higher-pressure gas charges, making them ideal for vocational applications, rough terrain, or consistently heavy loads. Heavy-duty options typically last 25-30% longer under severe conditions but may provide a slightly firmer ride.
Can I install these shock absorbers myself, or do I need special tools?
Installation can be done with standard hand tools including socket wrenches, a torque wrench, and potentially a spring compressor for certain applications. Most drivers can complete a front shock replacement in 45-60 minutes per side. Rear shocks may require lifting the truck and supporting the axle. Always torque mounting bolts to 125-150 ft-lbs for upper mounts and 200-250 ft-lbs for lower mounts. If you're not comfortable with the installation, any qualified truck shop can install them in about 2 hours total.
How long should I expect these shock absorbers to last on my Peterbilt 389?
Under normal highway driving conditions, quality shock absorbers typically last 150,000-200,000 miles. However, this varies significantly based on load weight, road conditions, and driving style. Signs you need replacement include excessive bouncing, nose diving during braking, uneven tire wear, or visible oil leaking from the shock body. We recommend inspecting shocks every 50,000 miles during regular maintenance.
Do you offer different brands, and what's the real difference between them?
We carry several trusted brands including Gabriel, Monroe, and Bilstein for Peterbilt 389 gliders. Gabriel offers solid OEM-replacement quality at competitive prices. Monroe shocks feature their signature gas-charged design for consistent performance. Bilstein shocks use monotube construction and are often preferred for heavy-haul applications due to superior heat dissipation. All brands we carry meet or exceed OEM specifications, but Bilstein typically offers the longest service life for severe-duty applications.
