1326-21 – Weld Yokes – 1351-21 Series – Butt Dia 2.435″ – Tube Dia Wall 2.560×0.065

• 1351-21 is a Toyota-specific series -- the U-joint cap geometry is Toyota-standard; do not substitute a domestic 1310 or 1350 joint
• 2.560" OD tube is a Toyota metric-derived specification (65mm); not interchangeable with 2.500" SAE tube pilot dimensions
• 2.435" butt diameter -- 0.060" larger than the butt used on 2.500" tube variants; confirms the Toyota-specific tube bore size
• 2.000" CL-to-weld is slightly longer than the 2351-20 variants (1.750" CL); indicates a different U-joint body length in the 1351-21 series
• Complete with a Toyota 1351-21 U-joint; see our catalog for the correct Toyota-application cross-reference

The 1351-21 series handles Toyota trucks and 4WD applications that fall in the capacity range above the 2351-20 used on lighter platforms. The 0.250" longer CL-to-weld on the 1326-21 versus the 2326-26 (both at the same 2.560" tube) indicates the 1351-21 joint body is taller than the 2351-20, requiring the weld to be positioned further back. Mixing the two series weld yokes on the same Toyota shaft is inadvisable -- the resulting mismatch in effective length will shift the rear joint operating angle and may cause vibration or interference with underbody components. This weld yoke is appropriate for all stock Toyota truck applications in this series.
