Q:Will this gearbox #97-8418GB fit my 2003 GMC SIERRA 2500 HD SLE 6.6L DURAMAX? If not what is the issue that prevents the fitment? Also why is a seal kit in the description, how is a seal kit applicable? Show Less

A:BEST ANSWERHi , thank you for reaching out. No, this will not fit. We have two listed for that truck. You can use the link below to see both. Do not forget to read the vehicle fitment information as they differ in spline count and and the number of banks on the sector shaft. You will have to check which one you have. Have a good one!

A Definitive Guide to Understanding Parallelogram Steering LinkagesThe pitman arm moves every time the steering wheel rotates. From the pitman arm, this steering movement is also transferred to the sector shaft, center link, and tie rods before reaching the steering knuckle on each front wheel.
A Handy Guide to Steering Box AdjustmentIt is able to accomplish this by multiplying the driver’s strength, meaning one rotation of the steering wheel is enough to change the directional course of the vehicle regardless of its size. This is why drivers are able to control and handle large vehicles like trucks with relatively small steering
