All Belltech spindles for 88-98 trucks are cast with 2400 in the back of them. The spud that the bearings ride on is different between the 2400 and 2500 part number. They use the same cast body though. You have the right units. Just take a tape measure and check the length of the machined spud on the Belltech versus your stock spindle. If they were wrong, it will be very obvious, like an inch difference. I ran into this exact same deal years ago. It scared me till a phone rep told me what the deal was.
