Common Questions
Before You Buy
What PSI actuator is included?+
The 1,600 PSI GEN 8 actuator is included. This is the correct pressure for both disc and drum brake applications.
Do I need anything else to complete the install?+
You will need DOT 3 brake fluid (not included). Basic hand tools and a way to mount the actuator to your trailer tongue.
What is the difference between integral and slip over?+
Integral kits replace your entire hub and rotor as one piece. Slip over kits mount the rotor over your existing hub — faster install, no hub removal needed.
Affects Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Colorado, Canyon & Hummer EV with integrated trailer brake controller.
That’s a known GM compatibility issue across the 2024–2026 lineup. Hydrastar has the fix — the GM Diode Module (#381-7074) is a plug-and-play inline solution.
