Replace your old trailer door spring with this heavy-duty system. This dual-spring setup lets you easily open and close the ramp door on your enclosed trailer and eliminates the risk of freefalling. Fits 81" to 96" wide trailer doors.Perfect device to making our life easier while closing our snowmobile trailer door. The video on line was excellent, product quality excellent as well. Like always, the shipping was perfect. Install took some time, but we got it done. The price was outstanding as well. We can always count on superior products, service and delivery from etrailer.
After destroying my single door spring I opted for this dual spring setup due to the door always being heavy to raise.
Wow what a difference! 3 turns on each spring and I can easily lift the cargo door with 1 hand (fingers).
etrailer always comes through when you need them. Fast shipping and a great product.
Door spring installed on a Mission 22ft 4 place deck over sled trailer.
We have a enclosed snowmobile trailer that was always difficult to open. Not now the new set up works great. Thank you for having a great product.
Works great I did beef up the support and added a center support and bearing. Probably would have been fine as it was but I’m an over do’er.
ive installed many ramp doot assemblies. the new brackets are much easier to install by myself. most times i would need a 2nd person. keep up with making things easier and better
We received our door spring and the drums were damaged. I called etrailer and they sent new ones out quickly so we could get our trailer door fixed right away. They were most excellent in customer service :)
The service is fantastic all the time!
The M394FR ramp spring I purchased a year ago has been working great. It was easy to install and out performs the original spring on my 24’ car hauler trailer.
Everything worked out great. Installed on a snowmobile trailer. The door originally only had a spring system on the bottom of the door. It took 2 people to close. After installing the M394FR it is a 1 arm operation. Highly recommend this product
jus what i needed
when installed it should be an excellent addition to trailer.
