2002 yukon xl shock options

[Fless]

ZW7 indicates a variation of the "Premium Smooth Ride" suspension. On the GMT800 chassis the "G65" RPO indicates the Nivomat shocks in the rear (and likely a front shock that is different from the Z71 or standard suspension). The rear springs are also softer. Take both RPO codes into consideration.

Those pics do look like the OE Nivomats. You can replace them with like shocks (manual, self adjusting Nivomats - $$) or convert to conventional shocks if you replace the coil springs with standard or Z71 springs.
