Propshaft Spacer for BMW xDrive Front Propshaft / Driveshaft The original equipment (OE) propshaft engages only approximately 25 mm of spline into the transfer case, which is insufficient. This limited engagement can lead to excessive wear, instability, and potential shaft wobble over time. Installing this spacer increases spline engagement by positioning the propshaft further into the transfer case, improving alignment, stability, and durability. This helps reduce premature wear and enhances overall drivetrain reliability. * All spacers are supplied with 4x longer bolts *
