6-3-3441KX – Slip Yoke – 1710 Series – 2.500″ Splines Dia – 16 Spline

Built for Spicer, the 6-3-3441KX slip yoke provides the axial compliance your driveline needs to accommodate suspension movement without vibration or binding. This 1710 series unit carries 16 splines at 2.500" diameter for a precise, rattle-free fit on the transmission output shaft.

Product Description

Slip yoke replacement is often overlooked during driveshaft service, yet a worn yoke is frequently the root cause of vibration complaints that return after U-joint replacement. The 6-3-3441KX restores the correct spline-to-bore clearance and presents an undamaged sliding surface to the extension housing seal, eliminating leak paths that develop with worn OEM yokes.

Part Details

Series Compatibility

The 1710 series U-joint cross bores must match the yoke ear dimensions of the 6-3-3441KX. Do not mix series -- a 1710 slip yoke should be paired only with a 1710 or compatible-series cross and companion yoke. Mismatched series results in incorrect snap ring grooves and potential joint separation under load.

Replacement Guidance

• Confirm 16-tooth count and 2.500" diameter match your transmission output shaft
• Measure center-to-end dimension if your application has tight length constraints
• Use assembly lube on splines during installation
• Reinstall transmission extension seal if it shows any sign of wear
• Phasing: reinstall driveshaft in the original orientation (mark before removal)
