OTK Engine Mount Clamp 1 Screw 92x28mm Full Clamp

The OTK Engine Mount Clamp 1 Screw 92x28mm Full Clamp (part number 0039.AB28) is a genuine OTK full-circumference engine mount clamp for OTK chassis with 28mm engine bay tubes. Unlike the cut-away variant, this full clamp completely surrounds the chassis tube to provide maximum clamping surface and grip. It is tightened using a single screw and is designed for OTK’s 92mm rail spacing. Two clamps are required per engine mount installation.

The choice between a full and cut-away clamp depends on the chassis geometry and engine mount position. The full clamp (0039.AB28) provides the maximum contact area around the tube, making it suitable for applications where maximum grip and minimal movement are required. The cut-away variant (0039.AB28A) is used where the chassis tube geometry or engine bay clearance requires a clamp with a section removed.
