1995 - 2000 GM OBS Truck Rear Shock Absorber Replacement (Cadillac, Chevy & GMC w/Bilstein Shocks)

In this video we will be going thru how to replace the rear shock absorbers on old body style (OBS) GMT400 type C/K trucks. But we will also be focusing on the regular production option (RPO) FG5 / 8X7 / Z71 / Y91 versions of shock absorbers, which would be for SUV vehicles factory equipped with 46mm Bilstein premium gas charged monotube shock absorbers in the rear.
The truck illustrated is a 1999 Chevrolet K1500 Suburban LT, but the shock removal and replacement procedure will be the same for any 1992 thru 2000 OBS truck or SUV. However the replacement parts ordering information below only applies to those vehicles with RPO FG5, as well as RPO 8X7, RPO Z71 and RPO Y91, for premium gas charged monotube 46mm Bilstein shock absorbers. So Cadillac, Chevrolet, and GMC for Escalade, Suburban, Tahoe, and Yukon across C1500, K1500, C2500, and K2500 ratings. Fitment for model year 2000 is limited to Cadillac Escalade, and Chevrolet Tahoe Limited/Z71.

great video real life situation appreciate the tips .thanks.

[@richh9904]

My 1998 K1500 still has the Bilstein rear shocks at 117000 miles. And the truck has very little rust. Benefits of living in the Southwest.

[@samsara2024]

Nice video! Please I need Help. I am looking for the right Blistein shocks for my GMC Surburban 1995 V6.5L Diesel 4x4. On the side it says 1500 but the axle looks like the one in your video with 8 bolts in the wheels. How can I know which is the right Blistein part number? Thanks

[@DrShock]

The K1500s with the 6.5L diesel over this model year range are all going to have 2500 grade chassis components. That's why you see the 8 lug rear. I don't see Bilstein shocks listed in the GM parts catalog for 1995 Suburbans which would imply that year didn't have them from the factory (but that could just be an error in the catalog currently). In the video description I include the current Bilstein numbers and they do support the application still from their own number. If you feel you still have original shocks from GM installed, in the video I mentioned the original GM number should be stamped into the shock itself, which you can use to map to something more recent or find NOS GM ones.

[@samsara2024]

@@DrShock Thanks a lot for your help! YesI have the rear diff with 14 bolts. I think is the same that you have in your video. I am thinking to buy the model Blistein 4600 24-024198 for the rear and the 24-104050 for the front. I hope I am doing well... i am new with this car :). My shocks are leaking oil

[@anthonyr829]

Thanks for this video, gonna try this myself. By chance do you have a video doing the front shocks?

[@enriquemartinez16]

Exceptional! Thank you!

[@MrBucidart]

Well done.

[@AmwayXS]

Hello Dr.Shock! Been following you ever since your OBS heads replacement videos, helped me out a lot on changing my heads on my 99 Suburban K1500. Question about these shocks, my truck came with a 3 inch block lift at the leaf springs. Currently has the Monroes GasMagnum, my question is if I need to upgrade to the Bilstein 5100, or if the 4600 would work just fine? Thank you, Alvaro

[@mybearisdead]

Gotta go with 5100s if you've got more than 1" of lift.

[@johnzamudio4230]

I have a 99 express 2500 rwd ND I just bought these shock b6 from rockauto but didn't come with hardware....where can I get the bolts ND nuts or can I just put regular nuts on the top ??? If the old one brake like in your video

[@DrShock]

Bilstein, or genuine GM repackaging of Bilstein, shocks should come with a hardware package. I have the GM part number for the mounting nut and bolt in the video description here, but that will be for these GMT400 style SUVs. It may not be the same part number for your Express van. The OEM nut is a prevailing torque type nut that is self-locking, so you can't use a plain nut or it will eventually come off/work loose.

[@johnzamudio4230]

OK yea I think that too I will have to see if the find oem style nut for it thank you

[@danielb-c9100]

What type of shots did the two thousand and eight silverado have I have z71 Package

[@DrShock]

The 2008 model year is outside the range of this video, but it would *not* be Bilstein for the pickup truck body style Z71s of that year originally. It's going to be one of two different black painted ACDelco premium gas charged parts which originally came on those 1500s. It depends on other RPOs the truck has, so running the VIN with the dealer will be necessary to clarify which one of the two shock numbers is appropriate for your 2008 truck.

[@danielb-c9100]

Ok
