According to Dexter, your 130123 axle is a 7,000 lb axle with a 91-1/2" hub face measurement and 72-1/2" spring center. I do have a solution, but unfortunately none of our 7k axles match this length. What I can offer is the Timbren Axle-Less Trailer Suspension System # TASR7KS01.
This system will fit any frame width so there is no need to match your existing axle length. It also upgrades and replaces your suspension components. For a hub and drum assembly you can use the # AKHD-865-7-2-EZ-K.... view full answer...
