new shocks for 95 k2500 suburban

eran tomer · Feb 23, 2021

hello
need to replace 4 shocks, want both on road and off road.
i prefer oil over gas since i heard they live longer.

there are bunch of types made by acdelco, am very confused.
for the fronts for instance there are couple of HD, 525-55 and 525-36, and there's 550-178 which is the most expensive and is "SLP"- what does is stand for?
and for the rears thers's HD 525-42 and what they call premium 540-5043.

thanks

Dear Newbie,

I feel that 4 EA 4600 Series BILSTEIN Shock Absorbers
Part # BIL24-016971 should serve you well both on and off the road, and you won't regret it! Although they are a little pricey but well worth it in my opinion, I hope you can acquire some.

Bilstein 4600 shocks are the best you can get for a GMT400.

For a K2500 Suburban:
Fronts are part # 24-104050
Rears are part # 24-024198

X3 for Bilstein 4600s. I run them on both of my '97s. Great shocks.

Been told that gas shocks have much shorter life than oil.

I've got Bilstein shocks on all corners on my C1500. My front have about 100K on them and the rear have ~40K (this was when I didn't know about doing all four at the same time.)

It's been nearly 8 years since I put the front shocks on and the truck rides just as good as it did when I first put them on.

If you're going to replace them, don't cheap out. Bilstein and KYB I've heard are the best OEM for these trucks.

I also vote Bilstein 4600 yellow shocks. I have them on my 1998 K3500, although I haven't put many miles on them. They're a little bouncy at first, but eventually, they smooth out and really improve drivability. Even with a heavy trailer bouncing around, handling is still comfortable. Unloaded, I think the ride is unmatched.

Although if you want off-road performance, I would suggest Bilstein 5100 silver shocks. They have valve tuning for off road and on-road more than the 4600s.

I know folks with over 150k on their shocks and they still ride like they did at 10k.
