Speedway Motors 91035140 Details

These forged steel drop axles are perfect for your next street rod project! Our dropped front axle sizes keep the wheels inside the fenders. Keeping the wheels tucked in the fenders allows for a lower ride height with adequate tire clearance. All of our I-beam axles feature a 4 inch drop and are designed as a replacement Ford front axle. With a versatile design, these dropped axles also allow you to use your stock 1937-48 Ford spindles or our Ford I-beam reproduction spindles. 47" wide from king pin centers, our street rod axles are sized according to original mounting specs, making a stress free conversion for your classic Ford styled front end.

1-piece forged steel design
Axle forging is ground smooth and bead blasted for a superior finish
4" drop
47" wide (king pin centers)
Accepts stock '37-'48 Ford spindles or Speedway Ford-style reproduction spindles
34" spring perch centers
Use with 29" cross spring
2-1/4" tall wishbone boss

Note: In order to use this axle with 2 inch wishbones, you will need to machine the inside of your wishbones and/or the axle for them to work together. The spring perch bosses on stock Model A wishbones are 2-1/4 inches, as are '37-and-later Fords, but '32-36 Ford wishbones come in at 2 inches.

Overall Assessment

Customers generally find the product well-built, with many describing it as high-quality and perfect for their projects. It's appreciated in the hot rod world for its suitability in ford axle and hardware systems. Most customers found that it fit well and exactly met their needs. Some skepticism was voiced about whether the axle was truly forged, but despite this, the customer recognized its heavy-duty nature and confirmed a willingness to repurchase. Overall, its qualities seem to set it apart in the market, with customers repeatedly praising its construction and stating they would buy it again.

Quality axle at good price

Bought this axle for a 1929 Model A project I am working on- It looks to be high quality and the cost was very affordable.

3.0

Doesn't appear to be forged.

Although this axle is "very stout" it is lacking the telltale signs of a true forging. The thick parting line down the center (usually ground down but still prevalent) leading me to believe this is a casting not a true forging. Even a casting would have a parting line (though a lot thinner) this is lacking a parting line altogether leading me to wonder just how this axle was made. Again this axle is very heavy duty and should work fine for many applications but I wanted to see some evidence of a true forging. This is the only reason I gave it 3 stars and not 5. Would I buy it again? Yes I would. Speedway has never let me down yet.
