DIMEnSIOn “B” IS THE TAILPIPE LEnGTH.
For approximate unladen stack height (12,000 pound springs) use the following frame heights:
tire size top of rail
11R24.5
43.5”
11R22.5
42.5”
285/75R24.5
42”
295/75R22.5
41.5”
*Use Prospector frame heights for more accurate results.
sample:
Tailpipe height 13’6” = Desired overall stack height = 162.0”
(–) Prospector frame height (–) 43.5”
(+) Frame rail depth (+) 10.6”
(–) Dimension ‘A’ from chart (–) 68.6”
= Tail pipe length = 60.5”
