BOSS Lowering blocks mount between the axle and springs on pickups to statically lower the vehicle 3″.
The BOSS 3″ Lowering blocks are angled to correct the pinion angle when dropping 3″.
The U Bolts are manufactured from hardened U bolts.
The blocks themselves are extruded from Aluminum (stronger than cast blocks) and have steel locating pins pressed in to provide secure centering.
BOSS lowering blocks fit most of the 2wd Utility vehicles equipped with leaf springs
