Want to drop my Tahoe to level.

[NORCAL SS]

if you look at the stock struts you will see there is only a little snap ring holding the lower spring mount. to lower the truck you run no spacers which in turn moves the lower spring perch lower down. Ive used thse struts on trailblazers/f150s/tahoese etc no issues. So you know the belltech ring is much thicker than the snap ring used on the stock gm shocks.
