movement When installed on the axle will they move? Forward or backwards while driving? One seems to be looser than the other that I received. How are they locked in place after its been installed and aligned. Can anything vibrate loose and does it need to be checked often or can it be set and not worried about?

The U bolts that clamp the rear end to the leaf springs must be loosened in order for this lowering block to be adjusted. Once the U bolts are tightened up the lower block will not be able to move or be adjusted. You shouldn't have to check the adjustment of the lower block but you will want to re-torque the U bolts after some miles have been put on the vehicle.

Will these work for a 1992 gmc Typhoon? How are you able to tell if it's adjusted to far to one side vs the other? Is there any tools for this or should I bring it to a alignment and frame place to have them installed?

Take some measurements of the spring width and the centering pin diameter to be sure if these will work for your pickup. We do not suggest adjusting the block any further than full contact of the spring pad on the rear axle. If you are not confident in the installation you may want to have them installed by a professional.

This item was designed and intended for circle track racing. If used on a street vehicle where it is exposed to winter weather and road treatment chemicals I would anticipate it being very tough to adjust after a length of time in that environment.

This adjustable lowering block is made from a machined aluminum block and uses a hardened steel bolt and pin adjuster. It has proven to take the abuse of circle track racing well. Depending upon the application you will want to limit the amount of offset you use this for. You do not want the block adjusted so far that it hangs off the end of the spring pad on the axle.

Bottom plate is not affected, only the axle moves as the bottom is fixed in position. For street use you need both sides the same with no rear steer or truck will drive weird . The are mostly used for circle track racing to add rear steer in the cars.

When adjusted so that the block is at the extreme front or rear then the U bolts will have some noticeable angle in the U bolts.

Pin moves an inch forward and an inch rearward from center. Block is all aluminum except the adjusting bolt which is steel.

The adjustable lowering block is made from billet aluminum, no cast aluminum. The design of part allows for the center pin to be adjusted on either side of center upto 7/8" which nets a total travel front to back of 1-3/4"
