I remember reading this interview, where Bacal mentions they were getting almost 15" travel, both front and rear... and with stock 200 series, upper and lower control arms.
"We utilize all stock suspension parts for instance upper and lower A-arms, bushing and the solid axle 5 link in the rear. All bushings are stock. The only change in suspension are the actual shocks.
We are sponsored by
King Racing Shocks, and the front runs two King Shocks per wheel. I have mounted a 3.5” coilover that passes through the upper mount (cut out) into a higher custom shock mount location that ties into the roll cage. the secondary shock is strictly a 3.5″ triple bypass. At the full droop and full bump, I get almost 15” of usable travel. This is possible with the stock arms, 4WD half shafts, and stock steering components.
As for the rear suspension, I punched through the bed floor, and from eye to eye, the top and bottom shock bolt mount is 47” in length at full droop, with the
King Kong 4.5” triple bypass. The rear coils have been removed, and a 2.5” air shock coilover holds up the LX in the rear. The rear suspension also has close to 15” of travel, but does not utilize air bump shocks front or rear due to the stock full class rules."
