What did you do to your NBS GMT800 Tahoe/Yukon Today?

[#1taho]

I got 4600s for $62 us on ebay

5100s likely come in varying lengths. Also keep in mind that the hd trucks have different shock mounts so dont get one of those. Also takenote that there is an old part # and a new part # for thw same shock.

5100s besides length are valved differently than 4600s btw. 5100s are digressive and 4600s are linear.

The two different front shocks in tbe 5100 series are:

Could you please explain the difference between progressive and linear, concerning shocks. Thx. I have kybs on my 03 dropped How, what would work best for my setup?

I was going to ask the same thing!

5100's are for raised/lifted vehicles; 4600's are for stock height or lowered vehicles.

For the 4600 is there a maximum height it can be dropped?

I'm sure that depends on how you drop it and whether you're talking front or rear. Drop spindles maintain suspension geometry so nothing changes. And I suspect that using keys to drop more than an inch causes the shocks (stock or 4600's) to be compressed further than normal so that's probably one of the reasons ride quality suffers. But I just installed 4600's in the front and they were the same length as the Arnott's I replaced which were supposed to be stock length. Rears need shock extenders when you use shorter springs so the geometry doesn't change, but the extenders only come in one size so that's a good question there. But 4600's are supposed to be stock length shocks I believe.

Friday I blew my trans so Saturday I ordered a Level 3 "Invincible" 4l60e rated at 800 HP from Performabuilt, including an FTI triple disc torque converter with a 2800 stall. This thing is a beast of a tranny.

I've never tried Belltech but I can say the 4600's I just installed on the front are some great shocks. Highly recommended.

I think I'm gonna go with the Crown lowering kit and either 4600 or Belltech shocks just a 2/3 drop the Belltech drops it a lot more
