They're Patterned after Gold Seal shocks which act with big end of rear spring to form what is technically a 4 link theory design. By making T-Bars parallel to & pivoting at/with big end of rear spring pinion no longer moves in arc when springs are loaded up. The preffered 2deg Pinion angle is constant, no bounce/change.
All inertial force gets fed back towards pavement plant patch & springs do not wrap up or deflect. Zero Wheel Hop, instead front of frame lifts left high like a huge lever which "springs" it off the Line, & truck gets gone in a hurry and decisively. Use tires that you can control spin on.
If there is too much Plant, hook up, & stick, things can break. I count on a bit of wheel spin to absorb initial impact shock. Too solid of a bite is too much,at least with torque of a decent 460.
I used Seamless Mild Steel Round Tube stock, MIG welded 'em up. I also used mild steel for my brackets & pivots, with some poly G bushings I had under the bench. Also they are on top & do not hang down where they can be seen.
FBp could you email me with details on those traction bars and maybe a simple skech. I 'm in the process of dropen a 460 in my 64 F-100 SB and will be changing the rear end to a f-150 31 spline rear end in the future. I have been taking a welding class at the adult school for the last 2 semesters and have access to there full blown welding shop to make the mods....thanks
