Thread: Distance between rear axle and frame?

That is why I said I thought 3-4 was more than generous. On my T I had shocks originally that were too long, and only had about 1.5 inches of travel. I used the car that way in the beginning and they never bottomed out, even over RR crossings and hitting rough bumps at high speed. I just pulled those shocks off and replaced them before Billetproof because with two passengers in the car it reduced the travel to less than I liked.

I agree that the figure Ken uses is probably correct in the real world, and that we don't need much more travel than that. But being the over-engineers we all are, we put a whole bunch of room in there we probably don't need.

I have also watched my front end dip over RR tracks and bumps, and it probably only moves 2 inches max., if that. On my '27 I have a frame tab on each side to mount the F100 shock mounts, it sits directly over the spring and is only about 2 inches away from the top of the spring. In many years of using it the spring never came up and hit that tab, the paint in that area is still perfect.
