2008.5 WK CRD rear suspension

I'm sure this has been beaten to death already, but I'm ordering new rear springs and shocks within the week and need some advice.

RC budget boost lift, 265/65R18 tires, roof rack, 4xguard matrix brushguard, engine skid plate, transmission skid plate, winch mounted on front receiver 6 months of the year. I plan on building a front skid this summer as well.

All suspension appears to be original mopar. Driving is mostly highway and city (not the best roads either, lots of bumps and uneven pavement), but sees occasional high speed gravel/dirt road driving.

Springs I was going to go with are the Moog 80919, and was thinking Ranco RS5000X or Bilstein 4600.

I'm trying to get as smooth a ride as possible, so advice is appreciated.

You might need a small wheel spacer with 265 wide tires. Also I've had Rancho5000 and i wouldn't recommend them over the bilsteins. They were too stiff in the cold .

Personally having both before, If you want a smoother ride and you're obviously driving on snow and ice and gravel ( like me ), you would be much better off running a 245/70-18 . Same diameter tire as the 265/65, but you will have better traction, less clearance issues all around and get better fuel economy too.

The lift and tires have been installed for a while. I do have 1.5" wheel spacers all around.

Do the Rancho's get that stiff in the cold? It's been averaging -30C here the last two weeks. What shocks do you have now and do you like them?

AH, sorry i forgot to look at your sig details.. . Moo point then .lol

I found the Rancho's great in the middle of summer but very stiff in the cold.
I've had my bilsteins for 7 years now and they've been great. I think it might be the monotube design that helps because i have skyjacker hydro twin tubes on the YJ and they are pretty stiff in winter too.

We pretty much have the same climate i'm sure. I live in rural MB and drive 10Km of rough gravel and another 20km of MB highways every day, so my shocks and suspension in general takes a beating .

I'm in rural Southern SK, 50km of highway every day plus the back road driving. Which Bilsteins did you put on? 4600 or 5100?

I have the 4600s. Bought them from Kolak, a vendor on the forum for cheaper then I could get them anywhere. I couldn't buy them at Rock auto today for what I paid 7 years ago.

Sounds like the 4600s are the way to go then if you're driving nearly identical conditions as me. I think they're only about $20 more than the Ranchos anyways. Thanks for the help

I have the 5100's with the 2" rear lift. They are great but are smoother at speed than when slow. I wish I had done the rear springs at the same time, I need to get around to that soon as they can't handle any extra weight in the vehicle without collapsing.
