Product Details

The Moog RS503 is a precision-engineered steering king pin shim (also known as a king bolt shim) designed to restore proper front end geometry and like-new steering feel. Used during king pin service or replacement, this shim sets the correct axial clearance at the king pin joint, eliminating looseness that causes wandering, shimmy, and uneven tire wear.

Key Features:

  • Engineered to restore like-new steering and handling performance
  • Precision manufactured to exacting tolerances for accurate king pin preload and clearance adjustment
  • Construction and design validated by Moog engineers for long-term durability
  • Easy to install — fits into existing king pin service procedures without modification
  • Part of Moog's trusted Problem Solver line, the preferred choice of professional technicians

Moog's Problem Solver philosophy drives continuous design improvements that extend component life and simplify installation. As the chassis industry's most recognized brand, Moog parts are engineered in St. Louis, MO and built to meet or exceed original equipment standards.

Great prices and fast shipping!

Great prices and great products. When it was received, the merchandise was correct and packed well. Thanks, will be ordering oil from this buyer from now on. (order #5647)

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

Easy to order

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

Easy to use website. The belts I ordered didn't have a picture but I knwew what I was looking for.
