2015 Duramax - reg cab long bed -- 2" rear lowering

[dennislbrooks]

Ok this stuff may be old news but I used the 1 inch hole in the lowering shackle - trimmed top hole - lowered rear about 1 1/4 inch. Clearances disappear if you go top hole.... Then I gave each front torque arm bolt 4 full turns. Looks like you raise about 3/8 of an inch for every 2 full turns --- total was 3/4 inch --- raised front of truck to take the weight off before adjusting. I still have about of inch bolt left.

This gave me 41 1/4 inch in the front from ground to top center of fender wells and 41 3/4 inch in the rear.

Headlights raised 2 inches on low beam. Have not adjusted them yet as I may like them better. Will see if it bothers others.

I may go 2 more turns on the front but will test drive first. I need to finish mowing before more rain tonite and tomorrow.
