IC34 – Increase Bushing – Length 0.9″ – From Tube 2-120 – Inside Dia 1.764″ – Outer Dia 3.5″

IC34 Increase Bushing 2-120 to 35-083

The IC34 is a driveshaft increase bushing transitioning from a 2-120 tube (2.0" OD x 0.120" wall) to a 35-083 tube (3.5" OD x 0.083" wall). Inside diameter is 1.764", outer diameter is 3.5", and length is 0.9".

Specifications

• Part Number: IC34
• From Tube: 2-120
• To Tube: 35-083
• Inside Diameter: 1.764"
• Outer Diameter: 3.5"
• Length: 0.9"

When fitting the IC34, confirm the existing tube is 2.0" OD x 0.120" wall (2-120) and the target tube is 3.5" OD x 0.083" wall (35-083). The 1.764" ID matches the IC35 (also from 2-120), but the IC34 has a larger 3.5" OD for connection to a 3.5" outer tube rather than 3.0". Verify both tubes against these specifications before ordering.

The IC34 represents a larger step-up than the IC35, going from a 2" heavy-wall tube directly to 3.5" OD in a single bushing. This applies to custom driveshaft builds where a significant diameter increase is needed. Confirm the 3.5" target tube is 35-083 spec (0.083" wall).

The IC34 ID of 1.764" and OD of 3.5" are the critical matching dimensions. Confirm both tube specs (2-120 inner, 35-083 outer) before ordering. Do not substitute the IC35 (3.0" OD) in an application requiring the IC34 (3.5" OD).
