I still can't decide on the Rancho 9K XL vs Bilstein 5100, but I think Bilstein is a better built product.

All street driving and truck is stock. I do tow a 24 ft enclosed car trailer with a decent amount of tongue weight. Perhaps the Rancho would be good since its adjustable?

I called "4 wheel parts" and they told me there is no 5100 available for a 2500 2006 or 2007. Part number F4BE5C604-HO (front) and F4BE5C14-HO (rear).

Hmmm!

 

go to ebay
top gun customz have one set for sale.....

 

I use them...

i also got mine for a 2006 on ebay from top gun customz

 

Got mine for my '07 from Lorenz.

Obviously, 4 Wheel Parts, or whom you spoke to, doesn't know diddly.

 

I just got a set of Bilsteins (Blue/Yellow)from Geno's Garage and I love them. Had 60K on the original crap... god what a difference a good shock makes.

 

I have a level lift. Is it the same part number or different?

 

shagginwagon...be sure to join out iaff thread we have going on!

If im not mistaken I think you have to go with 5150. My buddy just ordered mine for my truck.

 

5100s are good for 0" to 2" lift as per Bilstein. I was shopping locally last week and the shop had the rears in stock and could get the fronts the next day.

 

Thanks all. I spoke with Sean at Lorenz, nice guy! He said to really get rid of the rear bouncing, caused by the high spring rates, I would need the Bilsteins and also his DP leafs for the rear. That should do it since my truck is stock.

Well, crap... that is now about $2K for the anti-bounce mod. Very rough calculation
$294 shocks
$1,100 DP Rear Leafs
$250 apprx. Shipping
$200 apprx. install
$1,844

 

do the install your self and save the money. whats wrong with the way it rides? ill pee blood before i spend 2k on just the rear suspension. id take that money and save it for the tranny, but since you dont have the 48re, im sure i could put it to another use! look into thuren fab and kore too

I got an email reply from the guys at bilstein for this exact question. Remember that their shocks are made specifically for a particular vehicle. They have not released their 5100's for the 2006/2007 2500 or 3500 and said that they did not see it happening within the next 6 months. That being said, the guys at Top Gun Cumstomz advised me of the ones that could be used. basically, they are advising that you use the ones for other years as the truck has not changed all that much and they should work fine. Its your decision. I was thinking of going with their advice.

 

Ummmm......how about just get the shocks and install some weight in the back of the truck. Way cheaper than new springs.

But it is your money.
