My 2002 Silverado extended cab Z71, probably the most common version of the silverado. So heres what I've done to make it different.

Suburban Z71 rims with 285/70/17 tires
HD Guage cluster with transmission temperature guage
2009 Police Pursuit Vehicle Tahoe 13" front brake swap
2003 Suburban dual piston rear brakes
Upgraded parking brake hardware
ARE cap with windoors
Clear corner marker lamps
Aux lighting switch and wiring
Derale 9000 11x9" Transmission cooler w/ Donaldson hydrualic spin-on filter
Powersteering cooler (My truck has Z71 and heavy-duty cooling but didn't have a powersteering cooler)
KYB Steering stabilizer
Future mods:
GK Torsion bars
Hydrobooster swap
Zone 1.5" Body Lift
