Introduction:
Simply, Jessie Haines Fabrication JHF portal setups use fabricated housings, JHF outer C's, Hummer/JHF portal boxes and run either Toyota 8"/8.4" dropouts or Ford 9" dropouts. Portals offer an additional 3.9" of ground clearance over standard axles.
Budget: $25/30k complete. Housing, C's and knuckles, portal gears upgraded, axle shafts, steering, brakes, loaded differentials, tabbed out. Ready to run.
Parts Suppliers:
ComTac / Wolfer (Ebay)
Seco Parts (EBay)
Military Surplus Parts (EBay)
ADV 4x4
RubberDuck 4x4
Measuring/WMS:
Install diff with crosspin. Measure from pin to the end of housing (the 3.5” tube). Add 5”. Basic reference numbers, if you want a 65” WMS, the housing will be 39”. The combined length of both axle shafts will be 48”. A centered diff would require two 24” inner shafts. If the diff is offset 8” (not the pinion, THE DIFF), the shaft lengths will be 32” and 16”. NOTE: Spool diffs have no crosspin - a 1" spacer is required.
My 70" WMS with 42's on 20x10 wheels and 5" backspacing yields ~85" outside of tire (top)
