Yes. It arrives fully assembled and dynamically pre-balanced for a fast, hassle-free installation on the specified makes, models and years.
What is the driveshaft made from?
It is made from drawn over mandrel (DOM) seamless steel tubing, offering superior concentricity, uniform wall thickness, and more torsional strength and dent resistance than standard welded steel.
Are the components new or remanufactured?
The assembly uses 100% new — not remanufactured — components, including new tubing, yokes, CV joints and U-joints, and is built in the USA.
What are signs my driveshaft may need replacing?
Vibration at speed, a clunk on acceleration, or worn U-joints can indicate driveshaft problems. Diagnose the cause first; if the original shaft is at fault, this assembly replaces it.
