crawlster®4Wd-AX Steering Systems (Wraith/AX10/RR10*)

The world´s unique HighEnd BTA linear steering system for Axial AR60 OCP axles combined with Original Axial knuckles AX80061 (plastic) or AX30760 (aluminium).
Axial WRAITH pilots achieve an entirely new curve behavior with unprecedented curve radii, maneuverability and off-road capability. Steering angles are optimized up to 49° degrees.

  • outrageous steering angles up to 49° degrees
  • extreme maneuverability due to positive Ackerman effect
  • can be used on standard- and tuning knuckles
  • no steering bar in front of the axle – optimized banking angle
  • *not usable with dual shock setup

crawlster®4Wd – Spooky steering angle.
Up to unbelievable 49° degrees

The implementation of a BTA concept for the Axial WRAITH has always been considered difficult, if not impossible.

crawlster®steering systems accepted the challenge and tried a completely new approach. Using a linear guided BTA articulation with short hinge arms, in combination with meticulously dimensioned knuckle links, an incredible steering angle* became possible even with short travel distances and positive Ackerman, where the inside wheel (B) turns more than the outer wheel (A).

crawlster®4Wd – Not an 'off the shelf' solution

With the crawlster®4Wd steering system you can have a completely new driving experience – maneuverability and off-road capabilities are optimized to the limit by the positive Ackerman effect, with steering angles up to 49 degrees.

  • Positive Ackerman effect – immediate, drastic improvement of steering geometry/ steering behaviour
  • Significantly improved maneuverability even in difficult terrain
  • Corrects negative relative steering angle – the inside wheel steers more than the outside wheel

  • Fits all standard and tuning knuckles – optimizes the track angle difference to max. positive Ackerman

  • Totally new driving experience – plus the ultimate in looks

  • No steering bar in front of the axle – optimized banking angle – less snagging on the ground
