Kenworth T600 Shock Absorbers
Frequently Asked Questions About Kenworth T600 Shock Absorbers
Will these shock absorbers fit my specific Kenworth T600 model year?
Most aftermarket shock absorbers for the Kenworth T600 are designed to fit models from 1987 through 2007. However, there can be variations based on your truck's suspension configuration (air ride vs. spring suspension) and whether you have a standard or extended cab. Always verify the part number against your VIN or existing shock absorber measurements before ordering. Key measurements to check include extended length, compressed length, and mounting style (eye-to-eye, stem-to-stem, or combination).
What's the difference between OEM and aftermarket shock absorbers for my T600?
OEM shocks typically use the original Kenworth part numbers and match factory specifications exactly, while quality aftermarket options from brands like Gabriel, Monroe, and Bilstein often provide similar or improved performance at a lower cost. Aftermarket shocks may offer enhanced features such as nitrogen charging for better heat dissipation, heavier-duty construction for increased payload capacity, or adjustable damping rates. The main trade-off is that some aftermarket options may have slightly different mounting hardware or require minor modifications during installation.
How difficult is it to install shock absorbers on a Kenworth T600, and what tools do I need?
Installation difficulty varies by position, with front shocks typically taking 1-2 hours per side and rear shocks 30-45 minutes per side for experienced mechanics. Essential tools include a floor jack and jack stands, socket set (typically 18mm-24mm), penetrating oil for seized bolts, and a torque wrench for proper tightening to 65-85 ft-lbs depending on application. Common challenges include rusted mounting bolts, limited clearance around the upper mounts, and the need to support the axle weight during removal. Many drivers recommend replacing shocks in pairs to maintain balanced handling.
How do I know when my T600 shock absorbers need replacement?
Key indicators include excessive bouncing after hitting bumps (more than 2-3 oscillations), visible oil leaks on the shock body, uneven tire wear patterns, nose-diving during braking, or a noticeably rougher ride quality. Physical inspection should reveal any bent shafts, damaged mounting bushings, or corrosion on the shock body. Most T600 shocks last between 75,000-150,000 miles depending on driving conditions, load weights, and road quality. Heavy-haul applications or frequent off-road use typically requires more frequent replacement.
What shock absorber specifications should I consider for different driving applications?
For highway driving with standard loads, standard-duty gas-charged shocks work well and provide a comfortable ride. Heavy-haul operators should opt for heavy-duty or severe-duty shocks with larger diameter pistons and reinforced mounting points. Regional delivery trucks benefit from monotube designs that handle frequent compression cycles better. Off-road or construction applications require maximum travel shocks with protective boots and stronger seals. Consider shocks with zinc or e-coating finishes for better corrosion resistance in harsh weather conditions.
