Where can i find some springs for my hauler rear door. I already checked HD an Lowes and the ones they have are small compared to what i have. Any help

Garage door company or the internet.

Yup x2.. That way they can help get the right spring for the application.

i would recommend calling a garage door repair guy. the springs at home depot are for a flip up door and not a roll up door. the toy haulers use a rool up door on a torsional spring and they are DANGEROUS. i do alot of stuff myself, but im scared to death of the torsional springs. i recently had someone out to do mine and they lost it! put some dents in a pannel, lucky no one got hit by the cable cause that would have been ugly. service call should only be about a hundred bucks plus parts. well worth it

I was just at Walt's RV Surplus today and saw a bunch of em. They're # is (909) 823-0563 in Rialto, CA.

I was there today. I saw them too...

Are looking for Torsion springs ( wind up type ) or Extension springs ( stretch type )?? Torsion springs are mounted inside and use a cable and drum set-up. Extension Springs are generally mounted on the exterior along the sides of the door. Both are very dangerous- please be careful.

There is a company called Service Spring in Ohio that makes custom springs if that is needed.

I think your trailer is different, My WW uses the solid door garage spring.
