[edit] Chevrolet S-10 and GMC Sonoma

The suspension package comes standard on the S-10 Xtreme and 1996-1998 S-10 SS models, but was also available as a separate package. The package included a total lowered ride height of approximately 2" over stock (1.5" from suspension, ~0.5" from shorter tire diameter), thicker front sway bar (33mm), rear sway bar (23mm), quicker ratio (12:1) steering box,upgraded Decarbon or Bilstein gas shock absorbers, and a frame brace on extended cab models.

The lowering was achieved using front coils with a different spring rate, and a 3-leaf rear spring pack.

Wheels and tires were also upgraded to 16" x 8" cast aluminum rim with 235/55/16 Goodyear Eagle GA tires. The style of the wheel was determined if the vehicle had the Xtreme package or not. There are 2 versions of "ZQ8" wheels - 1996-2000, known most commonly as "old style", and 2001-2003, most commonly known as "new style".

The suspension package can be retrofit to any 1982-2003 2wd S-Series truck, although some parts require modification.
