Why the Hinge Kit?
Uniball-Based Design – Stronger and smoother than trailer bearing alternatives.
Weather Sealed – O-rings are sandwiched between the steel housing and aluminum spacers, keeping out water, dirt, and grime.
Smooth Operation – A light coat of grease along the O-rings ensures quiet, reliable movement over time.
DIY Friendly – Perfect for fabricators building custom swing-out bumpers or carriers.
This hinge kit is the ultimate solution for swing-out bumper builds, giving you strength, durability, and maintenance-free performance where it matters most.
