Mechanical Shock Absorbers

Match the shock absorber to the vehicle or equipment make, model, and year or to the machine’s specifications (mounting type, stroke length, and load capacity). Check whether the application requires twin-tube or monotube designs, and confirm compatibility with original mounting hardware and suspension geometry

Key specifications are load capacity (or spring rate compatibility), stroke length, mounting type (eye, stud, or ball), damping type (adjustable vs. fixed), and operating pressure or gas-charged versus hydraulic construction. Materials and corrosion protection are also important for durability in harsh environments

Adjustable shocks let you tune rebound and/or compression to suit driving style, load conditions, or work tasks, which is beneficial for towing, performance driving, or variable payloads. For routine street use or simple replacements, fixed-rate shocks often provide adequate performance at lower cost

Inspect shocks periodically for leaks, dents, broken mounts, or excessive rust; check for abnormal tire wear and handling changes that signal failure. Keep mounting points clean and replace worn bushings or hardware; shocks are typically replaced rather than rebuilt once oil or gas leakage and internal wear occur

Service life depends on use and conditions but commonly ranges from 30,000 to 100,000 miles for vehicle applications; industrial use varies with duty cycle. Replace them when you notice reduced damping, increased bounce, fluid leaks, uneven tire wear, or damaged mounts

Budget shocks usually cost less and can restore basic ride control, but may use simpler valving and shorter-lived seals; premium options offer more advanced valving, adjustable features, and corrosion-resistant materials for longer service life and improved control. Choose based on required performance, expected use, and total cost of ownership

Use the vehicle or equipment fitment lookup by entering exact make, model, year, axle position, or consult part-number cross-references; verify mounting style and measurements like extended/retracted length and stud/eye dimensions before purchase
