Description
A hidden wiper system for 1947–1954 Chevy and GMC Advance Design trucks. The hardware tucks up out of sight, so the cowl keeps its factory look while the wipers do the work.
Features
- Two-speed operation, with a delay circuit available.
- The kit includes everything except assembly lube, arms and blades, escutcheons, and model-specific switch knobs.
- Your stock pieces will still work in place of those parts.
- Runs off the switch supplied with the system rather than a GM column switch.
Choose your option
- 2 speed
- 2 speed with delay
Fitment notes
On 1954 trucks the stock defroster ducts will not clear this system. Use ducts from a 1947–1953 truck, or ducts from an aftermarket A/C supplier. Original upper-dash radios will not clear the system either, and one customer reported interference with an aftermarket radio. Cross-mount master cylinders likely will not fit once the system is installed.

Installation
A GM column-mounted wiper switch cannot control this system. GM switches ground the wiper motor while this system switches the positive wire, so wire in the switch that comes with the kit.
Have assembly lube, wiper arms and blades, escutcheons and a switch knob on hand before you start. Those are not in the kit, though your stock pieces will work. Escutcheons are the trim bezels that cover the pivot posts in the cowl.
