The Demco Hydraulic Brake Actuator w/ Drop and Electric Lockout # DM8204311 does not have a torque spec listed for it. Instead you'd need to determine what the hardware you used torque specs are and go with that.

Hi Rusty; the Dexter #84546UC3-EZ and etrailer #AKHD-5475-35-K will both fit a 3,500 lb axle but they have different bolt patterns. You already ordered the Dexter in the past so I'm assuming your wheels are 5 on 4-1/2. For the same bolt pattern…
