Fitment tips
Fitment can come down to more than year, make and model. Sometimes the sub-model decides, so start with the fitment table below.
- Drive type. If your car is all-wheel drive, make sure the part is for all-wheel drive, not rear-wheel drive.
- Engine size. For engine parts, make sure the engine size on the product matches your engine.
- Transmission. Manual and automatic cars often take different parts.
- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.
Manufacturer data can sometimes have imperfections. Still not sure? We are happy to help.
