Ford I-Beam Front Axles
Our experience has shown that these axles sizes keep the wheels inside the fenders. Keeping the wheels tucked in the fenders allows for a lower ride height with adequate tire clearance. The correct spring part number is provided for each axle.
Please note: If you are ordering an axle for use with original wishbones, measure the perch boss. Both 2″ and 2 1/4″ perch boss axles are in stock. Most 4-bars will use an axle with a 2 1/4″ perch boss.
We also have drilled axles and chrome plating available.

POSIES do’s, don’ts and tips
When you split the wishbone or run hairpin radius rods, the axle is forced to twist a little when you hit a bump, drop one wheel in a pot hole or simply go around a corner. I-beam axles will twist to accommodate this. I-beam axles work well with either split wishbones, hairpins or 4-bars.
Tube axles are very rigid and will not bend or twist without failing. Do not use tube axles with a split wishbone or hairpin radius rods. You will break something and it won’t be pretty! Use only a 4-bar setup with tube axles because the four separate bars and somewhat flecible rod ends allow the axle to rotate and compensate for a one wheel bump without twisting. Tube axles are great. We use them on our own cars, but they must be used with a 4-bar setup.
This is also why rear ladder bars that mount rigidly to the rear end and run out to the frame rails will twist the rear axle housing or break when run on the street.
