Nobody one wants to scrape their low rider, or wrestle with removing the front bumper! Trailer ramps are designed to notch into your existing trailer door to reduce the approach angle, allowing you to drive up into your trailer with no fear of scraping. Here are all the factors that go into finding a trailer ramp that will work for both your vehicle and your trailer.
Find your vehicle’s maximum approach angle
So that you can be sure your front bumper won’t hit the ramp on the way up, calculate the maximum ramp angle that will work for your specific vehicle. We've made it easier than ever to work it out with a simple step-by-step Yardstick Test.
Measure Your Trailer Door Length
Now that you know the biggest angle of approach that your car can handle, it’s time to measure the length of your trailer’s door length and height off the ground. This will contribute to identifying the trailer ramp length that will work best for your angle of approach and your trailer. Race Ramps has a convenient trailer ramp calculator that will help you visualize your options and provide you with some information about your measurements. Trailer ramp lengths can vary anywhere from 45" to 130", however it is ultimately your trailer door measurements and angle of approach that will determine the trailer ramp you need for your vehicle.
Measure the thickness of your trailer door
It might be a small measurement, but it's important. Each of our trailer ramps feature a notch cut-out, so you want to make sure that the trailer door can comfortably rest in that notch cut-out without creating too much of a dip or protrusion.
Make sure the ramp height is suitable
The ramp you choose should ideally not be taller than the combined height of the door thickness plus the notch, with an allowance of .5 inches. That is another important reason why we incorporate door height into our trailer ramp calculator.
Identify if your trailer door has flaps
Flaps could influence the angle that your car drives up the ramp, so if your trailer door ramp does have flaps, you will need to make sure that the ramp you choose has a cut-out to accommodate them. Measure their length, and be conscious of that measurement as you look for trailer ramps. Race Ramps offers two ramps that have 16 inch and 18 inch cut-outs for trailer door flaps.
