Redline Trailer Suspension - Leaf Spring Suspension - 30-20 Review Video

What happens to slipper springs over time is they elongate and flatten, which is exactly what seems to be what happened with your springs, as opposed to the wrong length being put on (that is, of course, possible, but less likely). You can replace…

Building a single axle trailer you will need the following items to install leaf springs. I have listed the part numbers for the PR626 Springs next to the items needed. 2 Springs - #e27SR 2 Front Hangers - #115917, 1-1/2 inch tall or #28-5, 3-1/4…

On the Redline Rear Hanger, part #30-20, the hanger has top stamped into one of the sides of the hanger. The hanger is welded to the trailer with the side marked top, facing the outside of the trailer with the word top showing. I am including a…

The inner bearings should be #LM48548 (1.375 inch inner diameter), outer bearing should be #L44649 (1.06 inch inner diameter) and the grease seal should be #58846. I would recommend you pull your bearings out to verify that but that SHOULD be what…

Your hubs are not directly compatible with any axle we currently carry. The 8-147 hubs are agricultural hubs and although very close to fitting will not work with the new axle spindles. My recommendation is to get your new axle with the kit that…

I'd be happy to help you with that. For starters, the #F008584-2 fenders you'd looked at are designed for 14 inch wheels, you'd be better served going with the #F008585-2 which are designed for 15 inch wheels like the ones you have.…

On the Redline Rear Hanger, part #30-20, which is the rear hanger included with kit #APS1, it is welded to the trailer with the side marked top, facing the outside of the trailer with the word top showing. So the U-shape part is what gets welded to…

The bushing on the Rear Single Axle Trailer Suspension Hanger is welded in place, and is not available separately. I walked out to our warehouse and pulled one of the hangers off the shelf. The outer diameter of the bushing is .76 of an inch as…

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 and…

Thank you for providing a photo of your trailer shackle straps showing the extra non-threaded portion of the Redline zerk-fitted bolts #126B2. Shackle bolts are intended to have a fairly loose fit with the shackle straps when installed properly. This…

If you check out the picture I attached you can see that the knurls of the wet bolts like the part #126B2 are supposed go through the shackle straps and not the bushing. I believe the issue you are having is you are trying to force the knurls through…

You will want the equalizer to angle in about 1/2 an inch so you'd need to compensate that by taking one inch off of the distance you mentioned so 27 inched would be correct distance between the hanger bolt centers.
