Part No. 2133-202 (also written 2133/202) Splined Sleeves & Slip Assemblies, 1.160" Splines Dia, Butt Dia 1.844", 27 Spline

The 2133-202 is a splined sleeve and slip assembly for BMW & MORE driveshaft applications, providing 27 splines at 1.160 inch diameter. Splined sleeves serve as the sliding element in a non-integrated slip joint, allowing the effective driveshaft length to vary with suspension travel while maintaining full torque transmission through the spline engagement.

Splined Sleeve Design and Function

Unlike a conventional slip yoke that slides on the transmission tailshaft spline, a splined sleeve assembly integrates the sliding function into the driveshaft itself. The sleeve -- splined internally to match the stub shaft -- slides axially while transmitting torque, eliminating the need for a non-standard transmission extension. This design is common in European and import driveshaft applications where the OEM does not use a conventional tailshaft slip arrangement.

The STEEL construction of the 2133-202 provides the torsional rigidity required for sustained torque transmission while maintaining the close tolerance needed to minimize backlash in the slip joint. Butt diameter of 1.844 inches accepts the specified tube wall for welding into a complete shaft assembly.

Fitment and Assembly Notes

• Verify the 27-spline count matches the mating stub shaft before assembly
• Apply driveshaft slip joint grease to the spline engagement before assembly -- dry splines wear rapidly and can gall under high torsional loads
• Confirm end-to-weld dimension (3.625) provides sufficient tube engagement for a full-penetration weld
• After welding, dynamic balance the complete shaft assembly to within specification before installation
