Pitman Arm 120 OE numbers
What this part does
Rotary-to-linear motion conversion
The steering gearbox sector shaft rotates through a limited arc — typically 30–35 degrees each side from center. The pitman arm is fixed to that shaft and swings through the same arc. Because the drag link or center link is pinned to the tip of the arm at a fixed radius, the arm's angular motion becomes a horizontal push-pull that can move the front wheels through their full steering lock.
Mechanical advantage and steering ratio
The length of the pitman arm directly affects the steering ratio. A longer arm converts a given gearbox rotation into more linkage travel, producing lighter steering effort at the expense of response — useful on heavy trucks. A shorter arm gives quicker, heavier steering — preferred on lighter performance applications. Aftermarket arms in different lengths are used by off-road builders to correct steering geometry after a suspension lift.
Load transfer into the linkage
All steering force generated by the driver and amplified by the gearbox flows through the pitman arm before it reaches any other steering component. This makes it one of the highest-stressed parts in the entire system — it must resist bending in the plane of motion, torsional twist from the splined shaft connection, and sudden impact loads from curbs and road hazards transmitted back through the wheels.

Where the pitman arm is used
Pitman arms are used on vehicles with a recirculating-ball steering gearbox, in either a parallelogram linkage or a solid-axle drag-link layout. These include many body-on-frame pickups, SUVs, vans and light trucks. Vehicles with rack-and-pinion steering do not have a pitman arm.
Sourcing notes for buyers
The pitman arm's spline must match the gearbox output shaft, and its length and drop set part of the steering geometry. Two pitman arms that look alike can differ in spline or taper, so the OE number is the reliable identifier.
What to match before ordering
- The OE number of the pitman arm
- Spline count and pattern at the gearbox end
- Taper and thread at the linkage end
- Vehicle model, model years and the steering gearbox fitted
How OE cross-referencing works
An OE (original equipment) number is the part number a vehicle maker gives a component. Each part in this catalogue is listed under the OE numbers it replaces and under the equivalent numbers other parts makers use, so the same part can be found from any of those codes.
Search an OE number to see the matching part, the vehicles it fits and its full cross-reference list. SLOOP parts are aftermarket replacements; vehicle brands and OE numbers are cited only to identify fitment. Search

What is a pitman arm?
A pitman arm is the forged-steel lever bolted to the output shaft of a recirculating-ball steering gearbox — the first mechanical link between the steering gearbox and the rest of the steering linkage. When the steering wheel is turned, the gearbox rotates its sector shaft, and the pitman arm converts that rotation into the lateral push-pull motion that drives either a drag link (on solid-axle vehicles) or a center link (on parallelogram-steering IFS vehicles). Without the pitman arm, the steering gearbox output has nothing to push against.
How many pitman arms do you carry?
120 OE numbers across 15 vehicle brands. Use the brand chips above to filter by your target vehicle.
Are these aftermarket or genuine OEM parts?
Aftermarket. SLOOP has been forging chassis components at our Taichung factory since 1984. We reference OEM part numbers under nominative fair use solely to identify vehicle compatibility — every part is form-fit-function tested against the listed OE specifications.
What is the minimum order?
USD 5,000 invoice minimum. In-stock parts: 20 pcs minimum per part. Make-to-Order parts: 1,000 pcs minimum per part (USD 5,000 auto-satisfied at MOQ). Ships globally from Taiwan. Payment terms, samples and letters of credit: please contact us by email.
How fast can you ship?
In-stock parts ship in 15–30 days from PO. Make-to-Order parts are 90–120 days (forge → machining → finishing → QC → packing). Sea freight from Taiwan port (standard); air freight available on request.
How do I confirm that a pitman arm fits a specific vehicle?
Search its OE number. The OE number page lists the vehicles the part is cross-referenced to by make, model and year. If you only know the vehicle, use the vehicle-brand links on this page to see the OE numbers listed for that make.
Can I order these parts under my own brand?
Yes. OEM orders (your brand on a standard part) and ODM orders (a part produced to your drawing or specification) are accepted, subject to minimum quantities and, where needed, tooling discussions.
Why can one vehicle model use more than one pitman arm?
A vehicle maker may fit different steering gearboxes, axle types or drive types across one model's range, and each combination can need its own pitman arm with its own OE number. Search the OE number from the old part or the vehicle maker's catalogue rather than choosing by model name alone.
Which parts connect to a pitman arm?
The steering gearbox output shaft at one end, and either a center link (parallelogram linkage) or a drag link (solid axle) at the other. Center links and drag links are listed in this catalogue as separate categories.
