Is this a front or rear shock absorber?
The 66412 is cataloged as a front suspension shock absorber for the listed Class 3-6 commercial applications.
Is the 66412 gas-charged?
Yes. It uses a nitrogen gas-charge that maintains tire-to-road contact by reducing aeration and shock fade, which helps improve ride and handling.
What are signs my front shock may need replacing?
Signs a worn shock may need replacing include excessive vibration, poor ride control, and reduced handling. Diagnose the cause before replacing, as other suspension parts can share these symptoms.
Should I replace shocks in pairs?
Replacing the left and right shocks on the same axle together as a matched pair is recommended for balanced ride control. This listing is for one shock; order two for a complete axle.
