Mopar Performance Torsion Bars
Do you know which thickness I’d want for a street strip 383 car?
Here are Torsion bar part numbers and specs:
0.81 90#/in P5249148 drag bars
0.83 100#/in 2535888-9 slant six bars
0.85 110#/in 2535890-1 slant six w/air - 318 w/o air
0.87 120#/in P5249149 (2535892-3) 318 w/ air - 340 std bars
0.89 130#/in P5249150 383 std bars
0.92 150#/in p5249151 *h/d handling
0.99 200#/in p5249152 solo/road race
1.04 250#/in p5249153 h/d solo road race-oval track
1.09 300#/in *p5249154 oval track 1/4 mi--optional 1/2 mi
1.14 300#/in p5249155 oval track 1/4 and 1/2 mile *
The bars I am selling in this post are one step above the factory size 383 bars. They would be a slight handling upgrade over the factory big block bars, but for the drag strip they may be too stiff and the weight transfer at launch may not be what you are looking for. I guess it depends on how often you plan to take your car to the strip vs. how much street time the car sees.
