Part Details

  • Quantity: 4 Piece Set

Direct Fit

Fits and functions correctly.  Competitors combine applications to reduce the amount of parts they carry, resulting in: incorrect vehicle height, poor response and an uncomfortable ride.

Rigorously Tested

Made from higher quality materials than the competition. Built to have a longer life in any environment or road conditions.

Matched Parts

Not all shocks and struts are manufactured the same.  Mixing and matching can result in ride quality issues and decrease the life of the parts.

Saves Time & Money

Over buying the parts individually, or having to search different parts that are correct for your vehicle (because we did it for you!)
