HUDY 107644 Limited Edition 4.0 mm Arm Reamer - Tuner Edition  [HSP-107644]

Exact hole sizing for suspension tuning

The HUDY 107644 Limited Edition Arm Reamer lets you accurately rework plastic suspension holes to the 4.0 mm dimension required for smooth, play-free movement. It is a straightforward tool for getting consistent pivots across arms.

Materials and feel

Manufactured from ultra light CNC machined Swiss 7075 T6 aluminium, the handle features a diamond knurl for confident handling. The pin has fine hand-ground micro scurfies that resize plastic cleanly without inducing stress or enlarging beyond the target size.

Personalise with cap colours

The handle ships with a black plastic end cap which can be swapped for optional colour-coded caps in violet, red, or blue to help identify different tools or setups.

Cleanly made and easy to use, the HUDY 107644 Arm Reamer is a useful specialist tool for builders who want repeatable suspension alignment and minimal slop.
