Question:

Question re Roadmaster Road Active spring kit. I have a 2023 Ford Transit T350HD. This rig does *not* have dual wheels but it is a 350HD highest GVWR without having duallies. Will the Road Active suspension kit fit this rig? Thanks!

Hello Alan, thanks for reaching out. Sadly, the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3623-HD will not fit the Transit 350HD models. If you need to beef up the rear suspension, a better option would be the SuperSprings Custom Suspension Stabilizer and Sway Control Kit # SSA43. This will work with the SRW 350HD models. it mounts above the factory leaf springs to help reduce sagging and improve stability.

The video I linked will show you the # SSA43 kit in more detail.

Many thanks for the reply and alternative. I see there's a used set of springs available at a significant discount. The picture on the product page is cropped so I cannot tell exactly what hardware is missing. If only commercial nuts and bolts are missing, I'm interested. Thanks for the help.

@AlanO So that used item is missing the poly spring pads, spring clamps, flange bolts and nuts. You might be able to find the nuts and bolts locally but the pads and clamps are more unique pieces and would likely need to be obtained from the manufacturer. I would have to recommend just getting a new one instead of the used one in this case.
