Fitment help
The exact information that decides whether a part fits, and where to find it on your vehicle or boat.
Start with the product page
Every product page lists the applications the manufacturer publishes for that part number. If your year, make, model and configuration are on the list, the part is correct. If your configuration is not listed, assume it does not fit and ask us.
Fitment data is accurate but not infallible. Mid year production changes, trim specific brackets, factory option packages and previous modifications all cause exceptions. Two minutes of checking beats a return.
Trucks and SUVs
Bed length
Measure the inside of the bed from the front bulkhead to the inside of the closed tailgate, along the floor. Round to the nearest inch and compare to the listed length. A 5 foot 7 inch bed and a 6 foot 4 inch bed on the same truck take completely different covers. Never go by the marketing name of the trim.
Cab configuration
Regular, extended, double, crew and mega cabs differ in floor length, which changes floor liner part numbers and step bar lengths. Count the doors and check whether the rear doors are full size or rear hinged.
Bed features that block accessories
- A factory cargo management rail system changes which covers and racks mount.
- A spray in liner can raise the bed rail height enough to affect a clamp on cover.
- A fifth wheel or gooseneck prep package puts hardware in the bed floor.
- A factory bed step, tailgate step or multi position tailgate changes clearance.
- A deleted or relocated spare tire changes under bed storage fitment.
Drivetrain and engine
Filters, ignition and cooling parts are engine specific, not model specific. Get the engine displacement and, on diesels, the engine family from the emissions label under the hood.
Cars and crossovers
Floor liner fit depends on the floor pan, the seat rail covers and the retention posts, which change with trim and with whether the vehicle has heated or power seats. Note the number of retention posts in the driver footwell and whether the vehicle has a dead pedal. For cargo liners, note whether you have a spare tire well, a subwoofer or a two position load floor.
RVs
Recreational vehicle parts are identified by the appliance or component brand and model, not by the coach brand. Find the data plate on the appliance itself. For a toilet, note the bowl height, the flange bolt pattern and whether the water line enters from the left or the right. For holding tank components, note the tank capacity and the valve size. For covers, measure the coach length including the bumper and any ladder.
Roof, awning and slide components often depend on the year the coach was built rather than the model year on the title. Use the build date on the federal certification label.
Boats
Marine fitment depends on the hull, the transom and the power, not on the boat brand. Note the hull length and beam, the transom type and thickness, the outboard or sterndrive brand and horsepower, and the existing wiring and plug type.
- Trolling motors: bow mount or transom mount, shaft length measured from the mounting surface to the waterline plus 16 to 20 inches, and the voltage of your battery bank.
- Transducers: hull material, deadrise angle at the mounting point, and whether the head unit is a matching brand or needs an adapter cable.
- Seating: pedestal base bolt pattern and post diameter, usually 2 3/8 inch.
- Propellers: shaft spline count, hub kit, diameter and pitch.
Where to find your numbers
- Vehicle identification number: driver side dash at the windshield, driver door jamb, and your registration and insurance card.
- Engine and emissions label: under the hood on the radiator support or the strut tower.
- Tire and loading label: driver door jamb, also gives you the factory tire size and axle ratings.
- Boat hull identification number: starboard side of the transom, upper corner.
- Appliance data plate: inside the access door or on the back of the unit.
- The old part: the part number stamped or printed on the part itself is the most reliable identifier there is.
