Product details

A six-piece trunnion and hinge set for the tailgate on a 1955–1959 Chevy or GMC pickup. It replaces the zinc-plated originals that rust and get noisy, so the tailgate opens and closes quietly.

Features

  • Six-piece stainless steel set that will never rust.
  • Trunnions CNC machined from 316 stainless steel and Delrin.
  • Hinge plates laser cut from 304 stainless steel.
  • Made in the USA.

Choose your option

  • Stepside
  • Fleetside (1958–59 only)

Fitment notes

The stepside trunnions include only the trunnion bushing, which is used with the stock tailgate bracket.
