how do u tell how many inchs your truck has been lowered
 

i bought this blazer already lowered and i need to know how many inchs its been lowered. Can't i just measure from the wheel well to the center of the wheel. Thanks for any help!

find a stock blazer in a parking lot , pull out your tape measure. then compare to yours

I'ma guess you have a 2wd.

If so, look at the rear. Does the leaf spring pack have 4 or more leafs, or only 2? If there is a few leafs they are factory (probley) and if there is only 1 or 2 they are either a set of lowering leafs or someone removed a couple leafs from the pack to lower it. The most common lowering leaf pack is 3 inches.

Also if there is any blocks between the axle and leaf pack, measure them and add that. Blocks range from 1-3 inch, although some may run 4 inch blocks.

The front, if the coils are VERY close to each other or there arn't many coil spirals, someone may have cut the factory springs shorter or heated them to lower the vehicle. I think most drop springs are around 2 inches. Also the spindle may have been replaced to lower the front even further. Spindle is normally 3 inch drop.

If it's a 4x4 post up and I'll break that down for ya. Otherwise you could measure the tire gap on another blazer, but that might not be accurate. They might be lowered/lifted or have larger/smaller tires over factory. Good luck regardless.
