Installation is straightforward for home mechanics, with the main tools needed being standard hand tools and a bearing race/seal driver. The included spindle adapter may require light pressing or heating for installation. Detailed consideration is given to compatibility with different fluid port thread types (SAE vs. metric), and Speedway offers a variety of brake hose and fitting options to complete the build.

Application

Ford 1928-48 spindles are generally your best choice when using an original Ford axle or spring behind application using 37-48 Ford spindles.
Chevy 1949-54 spindles are specifically designed for use on tube axles. A shorter, thicker axle stub makes this a slightly stronger spindle ideal for use with heavier street rods.

Ford kit features:

1928-48 Ford Spindles
- One piece forged 4140 steel
- Modeled after the 1937-41 round-back design
- Standard king pins fit to spindles
Speedway 11" Brake Kit
- 11" vented iron rotor, 1" thick
- 5 x 4-1/2" or 5 x 4-3/4" bolt patterns
- Wheel studs - 1/2" Fine (4-1/2" BP), 7/16" Fine (4-3/4" BP)
- Hub flange (hat) diameter - 6-1/4"
- D154 Wilwood calipers
- 7/16" banjo bolt to AN-3 line adapter kit
Traditional or Cross Steering Kit
- Flat plate steering arms
- 5/8" tie rod steering link
- 5/8" standard heim joint rod ends
- Seals-it 5/8" rod end seals

Features

Cross Steering vs. Traditional Steering

Traditional steering provides an original, period look, but will only work in these applications:

Four bar setup with '68-'73 Mustang box
Split wishbone or hairpin radius rod with reversed Corvair or '48-'56 Ford Puckup steering box
Parallel Steering Set-Up Guide (GIF)

Cross steering (using a Vega box) is the preferred method for nearly all cross spring, beam axle suspensions. Ford used this design from 1935-on.

Less bumpsteer
More comfortable steering column angle
Frees up foot pedal / bellhousing room
Cleaner vehicle profile
