The solid butt designation on the 3-40-2512U means there is no center bearing journal machined into this shaft — it is not intended for a two-piece driveshaft setup requiring a center support bearing. The 6.530" spline length provides extended engagement depth compared to standard-length variants; confirm the mating slip yoke has sufficient bore length to accommodate full insertion at minimum compression.
The 2.270" butt diameter fits 2.500" OD x 0.120" wall tube; the 0.120" wall is a heavy-wall specification. The 8.760" end-to-weld dimension must be factored into overall driveshaft assembly length calculations. For this spline configuration (16 x 1.500"), verify the mating slip yoke carries identical spline count and diameter before ordering the 3-40-2512U.
