Technical Overview of 27mm Axle Tubing

The 3RACING CRA-126 Crawler Ex Real Axle Wall Tubing is manufactured to provide a tighter axle envelope for competitive crawler setups. The 27mm section is intended to match Crawler Ex geometry and reduce play that can affect steering and traction during technical runs.

Engineering and Fit Characteristics

  • Compatibility: Dimensioned to align with Crawler Ex mounting points and axle interfaces for predictable integration.
  • Durability: Specified to withstand repeated trail stress without compromising alignment-critical surfaces.
  • Precision Fit: Designed to minimise runout and simplify setup adjustments for tuning-focused hobbyists.

Setup Notes for Tuners

When integrating the 3RACING CRA-126, check axle runout and verify link geometry under load to fine tune tracking and steering response. The reduced flex characteristics can change handling balance, so recalibrate shock and link settings when moving to this tubing.

How does this tubing affect axle alignment in tuned builds?

The tighter tube diameter and wall profile reduce play at mating surfaces, which helps maintain axle alignment under load and simplifies setting up toe and camber corrections on tuned crawlers.

Any recommended checks after installation for competitive setups?

Verify axle straightness, check link geometry through full articulation, and reassess steering endpoints and servo throws to capitalise on the improved rigidity.

Will changing to this tubing require uprated components elsewhere?

Upgraded tubing can shift load to other drivetrain parts; consider inspecting or reinforcing bearings, shafts and link mounts when moving to heavier tyres or aggressive running styles.
