G-70 arm: eliminating bridge bumper impacts between upper and lower sections after tuning

What the thread found

  • The Tiffen G-70 has a different internal structure than the G-70X and does not achieve the same smooth iso-elastic response, which may contribute to unwanted bumper contact.
  • If the lower arm section exhibits excessive swing, it is likely misaligned; operators should inspect all fasteners and verify the tilt setting at the socket block.
  • Manufacturer support and tuning videos from established arm experts provide reliable guidance for resolving this issue.

Depends on

  • Depends on proper socket block adjustment and fastener tension.
  • The behaviour may vary between G-70 and G-70X models due to structural differences.
