Sorry, They are the HD units. the part number is 116-324-0804 and the coil spring buffers are 115-325-2444. The springs list for $210 each and the buffers list for $7.00 each.
They fit most 116 chassis and 126 chassis. Check part number to make sure they fit your application.
I'll sell them shipped to the lower 48 states for a total of $80.00 for everything.
