Does anyone know what kind of shocks this '99 Jimmy came with? I need to replace the ones that are on it and want as close to OEM as I can get. THX, Larry

best shocks you can buy have them they are great this is from ther web site

The wait is over: now you can buy Edelbrock Performer IAS Shocks with the same advanced technology that has won the last four runnings of the prestigious Paris-Dakar rally, one of the toughest and most dangerous off-road events in the world. The Inertia Active System (IAS) Valve is the key. Unlike any other shock valve design, the IAS Valve can distinguish between body-induced rebound (as in cornering roll) and wheel-induced rebound (the wheel dropping into a pothole). It lets the shock respond instantly according to the driving situation, giving firm, stable control in cornering, and soft, compliant action when the wheels start bouncing along like basketballs. Its like having computer-controlled active suspension its just faster, smoother, more durable and less expensive.

you might get lucky and find an aftermarket shock that's close to OEM or will make you happy, but depending on how picky you are about the ride, the only place you will get a true OEM shock {ride} is at a dealer.

I asked the same question a few weeks ago, see this thread:

Blistiens for me - it's what my truck came from the factory with and will roll to the junk yard with. ;)
