Monarch Spartan chassis info
Just had some work done on my "98" Monarch (built 8/97 on a 4/95 Spartan Mountain Master chassis)

The front axle was rated 9,000 lbs by Barth, but it is actually an Eaton EFA-12F4 solid axle rated at 12,000 lbs.
Perhaps the tire or suspension limits lowered the rating...

15.0 x 4 inch brakes ABB1-551-C linings
Reyco air suspension
air bag (Goodyear) 1R11-201

The rear axle, rated 17,000 lbs has 16.5 x 7 inch drum brakes:

drums (TRP) DB1657B
shoes (TRP) RK4311EPR23
axle seal 393-0112
air bag (Firestone) W01-358-9213

All are widely available.

"98" Monarch 37
Spartan MM, 6 spd Allison
Cummins 8.3 300 hp
