Description

4062K Front Steer U-Build-It Kit – Build-Your-Own Racing Lawn Mower Front Axle


The 4062K EC Front Steer U-Build-It Kit is designed for racers and builders who want full control over their prepared-class race mower front axle setup. This kit includes the core components needed to assemble a front-steer spindle system, ideal for stock chassis builds with higher ground clearance—commonly used in USLMRA, ARMA, and other grassroots racing formats.


This system positions the steering tie rod in front of the axle beam, with a drag link spindle arm on the left side to connect to the pitman arm on your steering shaft. Just add your own axle beam, tie rods, and drag link to complete the build to your specifications.


If racing under specific class rules (USLMRA or ARMA), we recommend using one of our pre-built front axles that meet sanctioning body requirements.


Kit Includes:

  • 728 1/2" Heim Joints (undrilled)
  • 1/2"-20 Jam Nuts
  • 1/2"-20 Slotted Jam Nuts
  • FCRP-4053 Aluminum Caster End Plates
  • Steel Caster Back Plates
  • 1/2"-20 x 4.5" Hex Bolts (undrilled)
  • 12× 4065 1/2" x .154 Washers
  • 4062 EC Front Steer Spindle Set
  • 14× 2511 5/8" Radius Spindle Spacers
  • 5/8"-18 Slotted Jam Nuts
  • 999-31 Large Reusable Cotter Pins


Key Features:

  • Ideal for prepared class racing mowers with stock frames
  • Allows custom steering geometry and tuning flexibility
  • Compatible with 5/8" front hubs (spindle shaft diameter is 5/8")
  • Durable components ready for track use
  • Modular design—finish the build with your beam, tie rods, and drag link


Brake Compatibility Note

Spindles are not pre-cut for front brakes. If you plan to run front brakes, you will need to notch the spindle shaft for a brake key.


Recommended For:

  • USLMRA Prepared Class Racers
  • ARMA Racing Mowers
  • Builders using a stock mower chassis with front-steer setups
  • Custom mini-chassis and off-road kart conversions
