Wiper Wonder Kit · Universal

Wipers that work. Kits that fit.

One of the first universal electric wiper kits ever built, and still the one that fits where others can’t. A single flex shaft replaces the rods and pivots of a mechanical linkage or vacuum system, so the motor goes wherever your build has room and the kit adapts to the cowl you have rather than the one a factory built.

How it's built

Why a cable drive suits a custom cowl

Less room than a linkage

A mechanical linkage system needs a run of rods and pivots stretched across the cowl, and it forces the motor to sit in one fixed place relative to the shafts. That is a lot of hardware to find room for on a chopped or scratch-built cowl, and in a car with a filled firewall or a tight dash there may be nowhere obvious to put any of it.

A flex shaft replaces all of it with a single cable. It routes around whatever is in the way and takes up a fraction of the space, so the motor mounts where the build allows rather than where a linkage dictates. If the run is longer than standard, the 144" XLWD cable covers it.

Set it up the way the car needs

The two shafts can be configured for parallel or opposing wipe, mounted top or bottom, with the sweep set anywhere from 90° to 160° in 10° increments. That covers windshields that were cut down, laid back, or reshaped into something no factory ever built.

The shafts take arms that fit ½" or ⅝" fine spline knurls, which covers most of what builders are already running. Arms and blades aren't included, so you pick the finish and length that suit the car.

Electric wiper conversions for street rods and customs

Wipers are the detail that gets left until last on a build, and then becomes the reason a finished car never gets driven in anything but sunshine. Vacuum systems were marginal when they were new and are worse now — they slow under load exactly when visibility matters. On a pre-war body there may be no provision for wipers at all.


The Wiper Wonder Kit was one of the first universal electric wiper kits on the market, and took Best New Product of the Year at the 1991 NSRA Street Rod Nationals. Its flex-shaft cable drive is what makes it universal: a single cable replaces the rods and pivots of a mechanical linkage system, saving considerable space behind the dash. The motor mounts where the build has room, the cable routes around whatever is in the way, and the two shafts work with whatever arm orientation your windshield ended up with.
