Stiletto Steering Systems – Second to None




Originally introduced in 1973 for drag racing, the Stiletto Small box rack & pinion is compact, lightweight and smooth; the choice of Champions – the benchmark for driving control. With it's unparalleled performance and durability, it has also grown to be the standard for many other types of motorsports competitions.


The NEW release of the Stiletto Gen5 Small box is Next Level.


In addition to several design enhancements listed in more detail below, this 5th Generation update of the Stiletto Small box is also now available in four different ratios – further increasing it's versatility and enabling you to match the steering response to your application and driving style.



Ratios available:


  • 10:1 - Fastest
  • 12:1 - Faster
  • 15:1 - Medium
  • 20:1 - Slowest

Popular uses include:


  • Drag Racing
  • Micro/Mini Sprints
  • Off-Road
  • Land Speed
  • Formula/Baja SAE
  • Solar/High Mileage
  • Mini-Modified Pulling Tractors


What if you want a different steering response at a later date?



Gen5 has you covered – for ease of changeover, the pinion gear location relative to the mounting bolt holes is standardized on all Stiletto Gen5 Small boxes. This eliminates the need to relocate the steering shaft if you desire to switch to a different ratio assembly.





Gen5 – Outperforms your Expectations






Stiletto Gen5 Steering housings are the foundation for the ultimate experience in steering performance – masterpieces of engineering and precision machining, read on for more details.


To obtain the optimum rigidity and torsional stiffness necessary to maintain proper gear alignment, the housing is crafted from ultra tough 2024-T4 billet aluminum.


This aerospace grade aluminum alloy is significantly stronger and has proven to be superior over 6061-T6 or cast aluminum alternatives.


The knowledge gained as the industry leader over the last 5 decades has provided invaluable information about what works – and what doesn't.


You can trust Stiletto Steering's experience and commitment to excellence to deliver you to the winners circle.



Gen5 – The Smart Design





Unnecessary material has been removed in all the right places to save weight without reducing strength where it's needed.


The gear box housing and internals are also stabilized from the effects of thermal stress created during production with a patented Sub Harmonic stress relief process.


All aluminum components are anodized for corrosion resistance, added durability and good looks.



Gen5 – Super Secure & Durable Boots





Positive sealing anodized aluminum "threaded boot collars" provide the ultimate seal and retention of the unique nylon interwoven neoprene boots – adding life by keeping moisture and foreign debris out of the mechanism.



The Aurora PTFE-lined rod ends provide a secure and dependable connection.



We could save a few dollars by using cheaper components as others do – but why sacrifice performance and longevity of an important assembly?



Gen5 – Optimized for Performance





State-of-the art manufacturing methods have elevated Stiletto's legendary 'Swiss Watch' performance by holding critical tolerances to microns.



Both the rack & pinion are crafted of durable heat treated chromium alloy and exceed AGMA specs.



Black oxide conversion coating improves lubrication retention on critical contact surfaces and corrosion protection.



The hardened pinion gear is mounted on precision grease sealed ball bearings, and the rack glides on micro finish, align-honed, wear resistant silicon-bronze bushings with proprietary formulated Stiletto Lube.



Every detail applied in the construction of a Stiletto Steering rack and pinion steering assembly plays an integral part in delivering Stiletto's benchmark smooth action with near zero backlash and durability.



We can't (won't) tell you all the finite steps required to produce an assembly of this caliber – but will share that a Stiletto Steering System rack n pinion should be your only choice.



Gen5 – Rear vs. Front Steer Flexibility



On "rear steer" applications (with the steering arm pointing to the rear), the housing mounting bolts are to be positioned below the rack for proper steering wheel rotation. On "front steer" applications (with steering arm pointing to the front), simply invert the housing when mounting for the proper steering wheel rotation.



Built with out compromise in the USA.
