What Is a Mazda Steering Rack OE Number
Every Mazda steering rack carries a unique OE (Original Equipment) number stamped on the housing during manufacturing. This number is the most reliable way to identify the exact replacement part for your vehicle.
Mazda OE numbers follow a standardized format:
- KD31-32-110 — CX-5 2013
- GJ6A-32-110C — Mazda 6 2002
- UC2B-32-110 — BT-50 4WD
The same Mazda model can have multiple steering rack variants depending on production year, engine type, and market. Matching the exact OE number ensures correct fitment and reliable steering performance.
How to Identify the Correct Mazda Steering Rack
Step 1: Locate the OE Number on the Original Part
The OE number is stamped or engraved on the steering rack housing. On Mazda vehicles, the number is typically found on the main body near the input shaft or on the rack tube.
Step 2: Record Vehicle Details
- Full model name (e.g., Mazda CX-5 KE)
- Year of manufacture
- Engine type and displacement (e.g., 2.0L Skyactiv)
- Steering system type (Hydraulic / EPS / MSG)
Step 3: Cross-Reference with OE Database
Mazda occasionally issues supersession numbers when components are revised. Always confirm the latest compatible part number before ordering.
Step 4: Verify Physical Dimensions
If the OE number is unreadable, compare these measurements:
- Overall rack length (mount to mount)
- Input shaft spline count and diameter
- Tie rod thread size and pitch
- Hydraulic port positions (hydraulic systems)
- EPS motor connector pin layout (EPS systems)

Common Mistakes When Matching OE Numbers
Using only the model name
The same Mazda model can have 2-3 different steering rack variants. A 2012 CX-5 and a 2017 CX-5 use different racks. Always confirm the stamped number on the original unit.
Ignoring hydraulic vs EPS vs MSG type
Mazda uses three steering system types - hydraulic, EPS (Electric Power Steering), and MSG (Motor Steering Gear). They are not interchangeable.
Confusing LHD and RHD variants
Some Mazda models have different steering rack configurations for left-hand drive and right-hand drive markets. Confirm the vehicle's drive orientation before ordering.
Missing supersession updates
Mazda updates OE numbers when components are revised. Always check for the latest replacement number.
Compatibility Tips for Replacement
Year range coverage
Most Mazda steering racks fit a 4-6 year production window. The OE number KD31-32-110 covers CX-5 models from approximately 2012 to 2017.
Market-specific differences
Mazda models sold in Japan, North America, Europe, and Southeast Asia may have steering rack variations. Verify the vehicle's market of origin.
EPS calibration
Mazda models with electric power steering require IDS calibration after rack replacement. This applies to newer Mazda 3, Mazda 6, and CX-5 models.
Hydraulic system flush
When replacing a hydraulic steering rack, flush the power steering system and replace the fluid. Contaminated fluid can damage seals in the new rack.
Frequently Asked Questions
Where is the OE number stamped on a Mazda steering rack?
The OE number is stamped on the main housing body, usually near the input shaft or on the rack tube. Under-vehicle access or removal may be required to read it clearly.
My exact OE number is not listed. What should I do?
Check if Mazda has issued a supersession number for your application. Contact your parts supplier with the original OE number and vehicle details - they can confirm the current replacement part number.
Can a hydraulic Mazda steering rack be replaced with an EPS rack?
No. Hydraulic and EPS systems are not interchangeable. They use different mounting hardware, fluid connections, and electronic controls. Always replace with the same steering type.
What is the expected lifespan of a Mazda steering rack?
Under normal driving conditions, a Mazda steering rack lasts 150,000-200,000 km. Driving on rough roads or skipping fluid changes reduces this lifespan.
