I need a simple measurement off a 1 ton front end. A tape measure quality measurement will do.


Measure from the center of the driver's side A-arm front pivot out to the center of the tire with the tape perpendicular to the chassis.


A little eyeball calibration might be needed to get the tape perpendicular.

I have made some first approximation calculations for the relative loads our three different front ends input to the torsion bars: (1) OEM, (2) OEM + 2 inch wheel spacers and (3) the 1 ton front end with 3-1/2 inch spacers.

I measured our OEM front end with Alcoa wheels and Michelin tires and got ~16 inches.

The numbers I am using for the lever arms are: (1) 16 inches for OEM, (2) 18 inches for OEM +
2 inch spacers and (3) 19-1/2 inches for the 1 ton front end.

It is highly unlikely the 1 ton spacer mounting surface is the same distance from the a-arm pivot as OEM, so I would like a more accurate measurement.

All help and corrections appreciated.
