HUDY 107634 Arm Reamer Kit 4.0 x 120mm Replacement Tip Included  [HSP-107634]

Fine Adjustment for Suspension Components

The HUDY 107634 Arm Reamer is aimed at RC enthusiasts working on 1/8 scale models who need exact hole sizing. It resizes plastic bores to eliminate binding while avoiding excess clearance.

Reduce Unpredictable Handling

Small imperfections in arm holes can make handling inconsistent. The HUDY 107634 reamer puts the bore back to the right size so suspension motion is regular and predictable.

Purpose Built for RC Parts

With a 4.0mm tip and 120mm length, the tool suits common 1/8 scale fittings. Its hand-ground cutting features shear plastic cleanly, so the arm material retains strength without fraying.

Quick Reaming Method

• Align the reamer tip with the suspension arm hole.
• Apply gentle forward pressure while turning the tool.
• Push until touching the handle, then rotate as you withdraw to avoid chipping.

Do this process for a snug, non-binding fit that helps the car behave more consistently when driven hard.
