Yes.. the PVC inserts i picked up from trail Fab Worthy. it was just easier and they are lighter than the rubber run flats. I didn’t not want to contend with cutting the ribs of the MV rubber runflats.
When off on a trail, I will air down the tires. 15Psi in front and 10 Psi in rear for stability and traction. With the MV run flats, the ribs, over time will destroy the tire from within from running low air pressure, with the PVC inserts- no ribs to rub on inside of tire Still gives the ability as a double bead lock.
I picked this frame repair/upgrade kit from ORD. its it to be welded to frame, its already cut, pressed and drilled to fit frame snug and will greatly stiffen the frame channel by steering gearbox.
All that, and having the 4th Steering gearbox drilled, ported and tap'd for hydraulic lines, and putting a hydro ram in place of the steering stabilizer. This will move the force of steering to better mounting points and add roughly up to 2000 lbs of pressure( or so, I’ve been told…), to assist the factory power steering and making the whole system stronger, more reliable, and safe. And hopefully no more broken steering gear boxes. You have no idea how hard it is to limp it back off trail 5 miles with no steering..lol
I just recently found this site, and have added a build thread here, I haven’t posted much details, but will take plenty of pics and add here, once I can get started installing the above mentioned parts. Please note, 2 pictures posted were pulled from Trail Fab, i want to ensure, credit is given.
