lock Warranty Information keyboard_arrow_down
Moog fulfills their warranty through their individual dealers. That means that in order to receive warranty support, you will have to refer back to the original dealer you purchased the part from. Be sure to check the dealer's warranty support before you buy the part to make sure that they will properly support the warranty. If a dealer will only refer you back to the manufacturer in order to receive warranty support, then you may not actually have any warranty at all.
Part of our warranty process includes reviewing evidence of the defect provided by the customer. This is easily accomplished by providing video or images of the defective part so our staff can verify the claim and move forward with the warranty process. This removes the necessity of shipping the part back to our facility at the customer's expense.
WARRANTY:
Moog Premium Steering Components carry a Limited Lifetime Warranty. Moog R-Series Control Arms, Hub Assemblies, and Knuckle Assemblies carry a 3 Year or 36,000 mile Warranty (whichever occurs first). Above warranties are based on customers who own a car, van, SUV or light truck (less than 8,000 lbs. or 3,625 kilograms).
Moog warranties their parts to be free of defects in materials and/or workmanship during these timeframes as measured from the date of purchase.
If a Moog part should fail due to materials or manufacturing defect while under warranty, we will provide a replacement of the part upon return of the defective part.
Wearable RUBBER parts are not covered under warranty (Dust boots, bushings, bump stops, etc.)
Moog 4 Spline Heavy Duty Pitman Arm | '01-'10 GMC Sierra 2500HD

Unhappy Play
Play in your steering wheel, moving the steering wheel while your tires remain stationary, is a sign your truck's steering could use some help. Play is often caused by worn out joints in your truck's front end that have tangled with too many rough roads or potholes. A heavy duty 4 spline Pitman arm from Moog is a great solution for eliminating loose connections and restoring the steering of your 2001-2010 GMC Sierra 2500HD.
Sensitive Steering
Worn steering that allows your tires to meander back and forth, even just a little bit, is a quick route to wearing the tread off of your tires. The toe angle portion of your alignment is very sensitive to change as adjustments are often measured in the hundredth of a degree while camber adjustments are measured in tenths of a degree. Help your truck maintain its alignment and extend the life of your tires with a new Pitman arm from Moog.


3 or 4 Splines?
Identifying the correct Pitman Arm for certain Chevy and GMC trucks can be a trick thanks to GM using two different steering box output shafts that require different spline counts. We gathered a few pointers to tell which version your truck has as well as some tips for a smooth replacement in our Pitman Arm Blog. If you identify that your truck needs the 3 spline version we also have that variant of Moog's pitman arm available as well.
Fix & Forget
Moog understands how important steering is for your truck which is why they worked so hard to design features that promote precise steering into their Pitman arm. A heat treated stud with a greaseable design creates a robust part with an ongoing maintenance solution to deliver long term results for you and your truck. Fix it and forget it with the help of Moog's heavy duty Pitman arm.
