What have I bought? Rixtrix reckons I may have lucked out a bit on spec sheet.

Feedback so far..........

G80 and ZQ8 are posi track rear and sport suspension
G80 is the LSD, nice.
ZQ8 is a code and a trim package, so your truck is a ‘ZQ8’
They had a factory lowering kit, around 2in or so, springs and leafs. A tighter steering box and some other nice things. The Xtremes got the same setup but got a body kit and some badges.
This is kind of an aside since you're curious about rpo codes, but the guys who have the super sport S10’s look for the B4U code. SS trucks were the first to receive the ZQ8 suspension in 96 until they stopped the SS in 98. The ZQ8 then became its own trim package so to speak
That is the rear end. I think the codes that start with G are the gears for the rear. Not 100% but I think that's what it means. And G80 is a locking or semi locking rear end if I remember right.

GU6 = 3.42 gears
G80 = POSI limited slip
L35 = v6 4.3l vortec
M30 = 4spd overdrive transmission
ZQ8 = Sports suspension package


Thanks for the help.




YES..........


I know it is a repeat quote.


Just found this information, further to what we know.


Seems the S10 fans out there call this a ZQ8 truck.



Chevrolet S-10 and GMC Sonoma

The ZQ8 option suspension package comes standard on the 1999-2003 S-10 Xtreme and 1996-1998 S-10 SS models, but was also available as a sports package on either the S-10 or GMC Sonoma. 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. Some ZQ8 models were also equipped with a frame to axle "anti-hop" shock.
The lowered stance 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 Xtreme package used a different style rim than a standard truck equipped with the ZQ8 option. There are 2 versions of "ZQ8" wheels - 1996-2000 (also standard on 1996-1998 SS trucks), similar in design to 3rd generation Camaro wheels, and 2001-2003 (also used on Blazer Xtremes from 2004-2005), which bear a resemblance to an IROC Z28 wheel. Another variation among different models was in the center caps. S-10s and Sonomas used a grey center cap with the exception of the 2002-2003 S-10s, which featured a chrome center cap.
