Safety Considerations
Always secure the hood with secondary support before removing existing shocks to avoid accidental closure.
Wear gloves and safety glasses to protect against pinched fingers or snapped clips during removal/installation.
Never attempt to force a damper into position—always align ball sockets carefully to avoid damaging the ends.
Double-check that both ends of the shock are securely fastened before releasing the hood weight.
After installation, slowly test the full range of hood motion to ensure proper function and no obstructions.
Installation Instructions
Park the vehicle on a level surface and engage the parking brake to ensure safety.
Prop the hood securely open using hood support or a helper before removing old shocks.
Release the old hood damper by prying off the ball socket clips or unbolting the ends (if bolt-on style).
Align the new hood damper with the mounting studs and snap both ball sockets into place until they click securely.
Test hood movement by lifting and lowering it a few times to confirm smooth operation and proper damping.
When to Replace Your Truck's Hood Shock
The hood fails to stay open or starts closing on its own.
Noticeable difficulty in lifting the hood due to loss of spring or gas pressure.
Visible oil leakage, rust, or physical damage on the shock body or rod.
Excessive vibration or rattling of the hood while driving.
As part of routine maintenance or fleet part replacement to ensure consistent performance.
