I'd go with a double spring personally, Scott. These are typically going to be used on more heavy duty applications like your enclosed trailer with a pretty heavy door. In order to get a proper replacement though, you'd need measure the width…
Thanks for your question, Dale! That’s actually a pretty smart way to use these springs. We do have a couple of higher-capacity options that may work better for a heavier shed door: - Part #M326FR – 6-1/2 ft. long and rated for 150 lbs - Part #M346FR…

Yes. The Conventional Ramp Door Spring for 8' Wide Enclosed Trailer #M394FR fits 67-3/4" to 95" wide trailer doors. Your door with the brackets 81" apart falls in this range, so this spring will work well for you.
The spring with the black cable drum should always be mounted to your LEFT, standing on the inside of the trailer looking out. This is very important for proper operation. Dual spring systems, like #ERS160D96, have a red-coned and a black-coned…
Hey Rene, so the ramp door springs like the part #M394FR are not all identical in spec and capacity. So what that means is a double spring setup does not mean it's just the same spring on both ends compared to a single spring. This is why the…
For a 6' wide trailer we have the 120lb capacity #362SA6 and 80lb capacity #M364FR ramp door springs from M-3. Both of these options can be shortened by sliding the mounting bracket down and cutting the tube to fit your trailer. The #362SA6 fits…

Hello Ranieri, thanks for reaching out. You are on the right track here. The Curt Trailer Hitch #C99RV will indeed fit your 2026 BMW X3 M50 with the M Sport package. I was able to confirm this with Curt - it will install normally and properly on that…
Hi Steven; all of our axles are going to have the spring seats mounted underneath. If you can tell me the length of your axle (hub face to hub face measurement), I can see what is available for a replacement. If the spring seat measurement matches…
Single ramp springs are perfect for making your trailer ramp door easy to lift and lower. Ideal for small to medium-sized trailers, these springs provide the right tension to save your back and ensure smooth operation. Upgrade your trailer with a reliable solution that enthusiasts trust for quality and performance.
A single ramp spring significantly reduces the effort needed to lift and lower your trailer door. It provides the right tension to counterbalance the door's weight, making it easier and safer to operate. This is especially beneficial for those with heavier doors or who frequently use their trailers.
While installation is generally straightforward, some find adjusting the tension challenging. It's important to ensure the brackets are correctly placed and the spring is wound properly. Using tools like a rebar can help with winding, and having a friend assist can make the process smoother.
Single ramp springs are best suited for small to medium-sized trailers. They provide adequate support for doors that are not excessively heavy. For larger trailers, a dual spring system might be more appropriate to handle the increased weight and size.
Regularly check the spring tension and ensure all components are secure. Over time, the tension may need adjustment to maintain optimal performance. Inspect for any signs of wear or damage, especially if the trailer is used frequently or in harsh conditions.
Upgrading to a single ramp spring can transform your trailer experience by making door operation effortless. It enhances safety by reducing the risk of injury from heavy lifting and ensures smoother, more reliable performance. This upgrade is a game-changer for frequent trailer users.
