Why Customers Choose CarBus24

Our Promises to Every Customer

Genuine Promise

Checked against the OE numbers above before listing.

Money Back Guarantee

Get the item you ordered or your money back.

Secure Transaction

Your payment info is protected at all times.

14-Day Returns

Cross-referenced parts are cataloged as fitting the same application but are not guaranteed to be identical to the original manufacturer part. Verify fitment against your OE number or VIN before ordering.

How to Confirm This Part Fits Your Vehicle

Reference/cross-reference numbers vary by engine, transmission, chassis and production date — not by number alone. Before ordering, compare your original OE number against LR155421 number by HITACHI listed above, and check the dimensions or specifications against your original part.

If you’re unsure, contact CarBus24 with your VIN or the number printed on your original part and we’ll confirm the correct match before you order.

OE vs. Aftermarket Parts

OE (SACHS, Ford, Mazda)	Aftermarket (FAST, Valeo, LUK, Exedy)
Matches original manufacturer specification	Cross-referenced to the same application
Typically higher price	Typically lower price
Direct OE part number	Equivalent fit, different part number

Frequently Asked Questions

How do I know if a part matching LR155421 number by HITACHI fits my car?

Compare your original OE number against the OE Reference Numbers listed above, and check the dimensions or specifications against your original part.

What is the difference between OE and aftermarket parts?

OE parts match the original manufacturer specification. Aftermarket parts are cross-referenced to fit the same application, usually at a lower price.

Can I search by my vehicle instead of an OE number?

Yes — select your vehicle from the sidebar to see parts confirmed to fit your car.

What if I'm not sure which OE number I have?

Send us your VIN or the number printed on your original part and our team can confirm the correct match before you order.
