I assume you are talking about getting your
oil pan or bell housing over your ramp when you are loading your car.
If so there are a couple of things you can do.
1) Jack your trailer up higher in the front to reduce your loading angle.
2) Add an extension to your ramp. I used a piece of 3/4" exterior grade plywood 18" Wide by 8' long. I attached it to my loading ramp with a piano hindge and used four two by fours (2x4) about 15" long cut into a wedge to support the tires as they are rolling up on the ramp.
No problems holding the weight of the Cobra but it does make the ramp a little heavier to lift. When it warms up I will play with the tension on my spring that helps lift the ramp.
I hope this is what you are refering in your post. Good luck!
