Old Products: threaded stuff

When we ran a full service chassis fab/turn-key hot rod shop a number of years ago, it was always useful to have threaded things around to weld into the frame for some kind of mount, etc.

Here’s a list of all our threaded things for your reference:

Step Notch Kit, Universal, PR

In stock
Product Details
Brand: Welder Series
Thickness: 3/16"

A universal step notch kit that's really easy to assemble and install. The pieces fit together using alignment tabs to make clamping and welding on your bench a breeze. Available in two widths: 2-5/8" and 3-3/8".

Typically used in the classic/mini truck market to drop the frame past the rear axle. 2 widths available: 2-5/8″ and 3-3/8″ wide outside. 6-1/2″ from the top of the original frame to the top of the notch. Made from 3/16″ pickled and oiled mild steel. Sold in pairs.

The notch depth will vary, depending on how tall the frame rails are, and what sweep the original frame rails have. The S10 we used for our installation article, for instance, has 4″ of axle clearance with 18″ wheels when the frame is laying on the ground.

On the market since 2010.

Ready-to-weld or welded. Save some money buying the ready to weld kit, or save some time buying the welded kit. You’ll probably spend less than an hour welding it yourself.
Alignment tabs. No guesswork when it comes to squaring it up. Easy to clamp while you’re tacking it together. The original two piece step notch. Inner boxing plates are also included.
Weld it off the frame. The majority of the welding is done on your bench, where you can position the piece for the best weld. When you’re done welding the notch, just set it on the frame rail and weld it in place.
Sits on outside top corner of frame rail. If you choose to grind the welds, you’ll have a smooth transition from the notch to your frame rails.
Integral inner frame rail boxing plates. The inner plates weld to both the upper and lower flange of a C channel frame rail for strength.
