Hi Josh; we don't have a kit but I can get you the parts you need. I'm assuming you have electric brakes right now so you're going to need the EOH actuator along with the brakes and hydraulic lines. I recommend the following:
-Dexter Hydraulic Drum Brake Kit - Duo Servo - 12-1/4" - Left and Right Hand Assemblies - 8K # 23-402-403
-Hydrastar Electric Over Hydraulic Actuator for Drum Brakes - 1,200 psi # HBA-12 (the 1,200 psi model is required for 8k axles)
-Hydrastar Hydraulic Brake Line Kit - Single Axle - 15' Long # HS496-151
Or
-Hydrastar Hydraulic Brake Line Kit - Single Axle - 25' Long # HS496-251
I don't know how big your trailer is so you will need to choose the appropriate length for the brake lines. Since you said "axle" I'm assuming it is a single axle. If it is a tandem axle trailer you can use the # HS496-152 or # HS496-252.
