Applications

- Class 8 conventional drive axles using the Eaton ES2 16.5 in x 6 in S-cam brake
- Heavy-haul tractor configurations rated to 23,000 lb GAWR per axle
Order one kit per axle end (two kits per axle, four kits per tandem). Confirm shoe length (16.5 in) and width (6 in), FMSI 4725, and Eaton ES2 hardware before installing — the 4709 / 4720 / 4707 shoes are similar in appearance but use different anchor and roller geometry.
