The closest spring pads I can find are for a 3" diameter axle. Will these work? Can the gap be filled in and be strong enough? | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | O'reily's has universal spring perches. They may fit better than what you are finding.

They can also make you custom perches, I believe... Axle perch parts

Thanks | | | | | Joined: May 2005 Posts: 8,878 . | | . Joined: May 2005 Posts: 8,878 | I like the ruffstuff perches, one of the few places with narrow ons that are also long, not for a trailer axle. The ones I needed were to fit about a 3-5/8” tube, they wouldn’t custom make them at the time so I ordered some for smaller tube and machined the radius to suit. Wouldn’t weld a gap, get them to fit real tight before welding in place. Also, don’t forget to carefully measure and set pinion angle before welding spring perches on.
