Redline Trailer Suspension - Leaf Spring Suspension - APS1 Review Video

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind…

I spoke with my contact at Dutton-Lainson regarding your Hand Winch #DL15303. On this particular unit the handle can in fact be reversed (to be on the left side instead of the right). In order to do this, you will basically need to take apart the…

If the shackles aren't angled slightly you run the risk of the equalizers angling and having the shackles on the wrong side of the springs. 28 inch leaf springs are hard to come by so your best solution will be to either go with replacement…
