Precision link for performance tuning

The 3RACING Crawler Ex Real M6 x 86mm Linkage (CRA-123) is specified for builders wanting reliable link behaviour during aggressive crawling and setup sessions. Its dimensional accuracy supports repeatable geometry adjustments and consistent on-track response.

Engineering and setup considerations

With an M6 thread and 86mm nominal length, this linkage allows fine tuning of roll centre and steering leverage in competitive crawler rigs. Use it to micro adjust handling balance when pairing with different axle and link configurations.

Installation for tuners

Install the CRA-123 with standard metric tools and verify torques to maintain positional accuracy. Periodic checks of fastener seating and thread condition are recommended to preserve tuning consistency over time.

What tolerances should I expect?

Expect standard hobby grade tolerances; measure against your existing links to confirm alignment. The CRA-123 is intended for precise, repeatable setup work rather than custom machining fits.

How does link length affect roll centre?

Link length changes alter the lateral and vertical position of suspension pivots, influencing roll centre and body roll. Use small incremental changes with the CRA-123 to dial in handling.

Recommended maintenance for repeatable setup?

Maintain clean threads, apply appropriate threadlocker where needed, and check fastener torque after initial runs to ensure the linkage retains the intended geometry settings.
