Common questions
- How many miles will HD Shocks last on a tractor?
- We have HD Shocks on semis running past 300,000 miles. Mileage depends on the truck, the load and the roads, so have them checked once a year and rebuild them when they need it instead of replacing.
- Can HD Shocks be rebuilt?
- Yes. Every HD Shock is fully serviceable, so we rebuild it instead of you buying new.
- Will these help with cab ride and driver fatigue?
- Yes. Better damping means less pounding through the seat and steering wheel, and a fresher driver at the end of the shift.
- Can you help with more than one truck?
- Yes. Tell us what you run and we'll match parts for every truck.
- How fast can you ship?
- In-stock orders usually ship in 1 to 2 business days. Special or quote-only parts take longer, and we'll give you a date when you order.
