Anybody off the top of their head have a reasonable idea on how to lower the rear of a 55 with TL? Fabricated load pins for the front.

I'm thinking of loosening the U bolts and fabricating longer ones and just inserting 2" blocks that have a circular groove to conform to the axle tube.... Any objections besides the usual...Why?

I am lowering the overall height of the car, A flick of the TL switch will level it, or drag the tail or rake it towards the front, i have fabricated adjustable pins for the height on the front. I am just trying to decide the safest way to lower the rear about 2 inches. Inexpensively.

Why not just adjust the turnbuckle??

If you just want to change the rear, then adjusting the turnbuckle will do it but if you want to lower the entire car equally keeping it level, then I believe the proper way is to reduce the amount of twist on the long bars allowing the vehicle weight to lower it.

This is usually done by the different links in front. A shorter link equals less twist so overall, the car will lower. Whether you can get the two inches you are looking for is not known--each notch on stock lengths was said to change height 3/8" on new bars. Not sure if the spacers you are thinking about would do that since the tension on bars would be the same--although raising the axle would lower the rear, am thinking the front might be high.

After the new height and neutral point is established, the compensator position for short bars would have to be determined for neutral. The turnbuckle attachment to the long bar would then be clamped to the new location.

EDIT: Under car at approx front drivers seat location is a short rod connecting the level switch to the long bar. In the middle of the rod is an adjustment turnbuckle. Lengthening or shortening the rod changes the point the switch activates the compensator.

As HH56 indicates above i would start by using SHORTER front load links.

ok. it's a 55. 55 used differnt front load link pins from 56. Count the grooved rings on the load link pins and report back.

Guys....my load pins in the front are fully adjustable.(see pic) I am just wondering about the rear. Also my TL system has no compensator, it is on a two way momentary switch and you kind of use your ear to know where to stop it one way or the other.

It is a little misleading saying you don't have a compensator. I think you mean to say you do not have the control box wired in but just ground one solenoid or the other to engage the compensator to change the stance of the car. Perhaps you could mount a small level so that you could see where the car was regarding attitude. If you don't have the control box wired in, then the turnbuckle has no effect. I hope you haven't bypassed the limit switch as that can have a disastrous result.
