Thank you for the kind words, Lonner!

The Demco Hydraulic Brake Actuator w/ Electric Lockout # DM62VR is designed for disc brakes which require a higher psi rating than drum brakes do so you'll want to use one rated for drum brakes like the Dexter DX7.5L A-60 instead:

- Dexter DX7.5L A-60 Brake Actuator # DX83FR

Please note the slightly different bolt pattern for this coupler, plus it it doesn't come with a lockout so you'll need to add the Solenoid Valve # T4748800 to get that electric lockout feature added to this.

Hello Eric, The #K2R35DKG is Dacromet-coated, and the calipers are treated with KodaGuard. The #K2R35DS, on the other hand, is made entirely of stainless steel, hence the higher price. If you're in an area where road salt is common or if…

Atwood is no longer making actuators at this time so there are no replacement shocks for their actuators anymore. Especially for ones as old as yours. So what you'd need to do is replace the surge actuator with a similar A-frame actuator like the…
