Do All Suspension Bolts for Leaf Springs Need a Bushing

Question

Question:

Does the upper shackle mount use a bushing? Or does it just ride on the outside edges of the shackle bolt when installed? Can a tube be welded in to install a bronze bushing for longer wear and less stress on the shackle bolt?

You need to have a bushing installed on each bolt that comes in the Single-Axle Trailer Hanger Kit for Double-Eye Springs # APS4.

For this I recommend picking up the Nylon Bushings # SP05-060 which have the appropriate inner diameter and length for the hangers, and comes with 6 bushings to match the number of bolts in the kit. The only thing you'll need to check on is the 3/4" outer diameter to make sure these fit inside the leaf springs (if your leaf springs didn't come with bushings).

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Answer 9

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…
