- Series: 1810

When fitting the 6.5-4-4571X, confirm the output shaft has 44 splines at 2.274" pitch diameter. The hub diameter of 3.000" and through hole of 2.500" are critical clearance dimensions for the bearing plate mounting configuration. The 5.250" CJ-to-end measurement affects driveshaft working length — verify this against the driveshaft build specification.
The 1810 series has higher torque capacity than the 1710 series. The BP (bearing plate) style uses a flat plate for U-joint retention rather than straps. Confirm that the mating U-joint cross is also rated for 1810 series before installation. The 6.5-4-4571X is designated as 1810BP — verify the BP plate bolt pattern matches the mating cross cap dimensions.
