I got a pair of bilstein 4600, and looking for a correct way to install it. Probably it’s a dumb question, what side goes up, blue or yellow? Does it matter? I just googled it, and I see different people install it in different ways...

 

Boot down.

Just installed 4600s rears on my 18 SCREW last weekend. You will like the difference.

 

Cool!
I got one today, somehow the second one should arrive next Tuesday. Cannot wait for it

 

Excellent...can't wait to hear your thoughts.

I wouldn't say it is night and day difference but it is a good improvement. A lot less hop/ shudder on rough bumps and a bit less body roll in turns.

 

BTW, did you torque the shocks lug nuts?

 

Install so the label on the shock is oriented correctly. If the label is upside down, the shock is upside down.

I did not. Probs my will check then once I get it back from the shop.

 

OEM spec is 66 ft lbs. I just installed rear 5100s on my truck on Monday.

 

Installed it today... After all positive feedbacks, I was expecting to bit more. I took a quick ride to the city, didn't notice any difference at all. After that I took some dirt road, it was a bit better than the OEM shocks. I will test it for a few weeks, and will decide if I want to keep it.

 

I did the same, Not the big improvement I was expecting. In some ways the stock shock was better.
