I am looking to get the Rancho 4" kit for my 06 Screw 4x4. I was wondering what shocks you guys would recommend. I dont do any off roading with the truck. I know they have a special going, and if you buy the lift and 4 RS5000 shocks you get a $400 rebate and with the RS9000xl you get a $500 rebate. Are the rancho shocks any good or are the Bilsteins better. Also I was looking to keep the stock 20'S for now, so what tire size can I run with those and the 4" lift without doing ang hacking of the inner fenders. Last, where does anyone recommend getting the lift online for the best price. Thanks for any help. Mark

 

I thought the Rancho lift came with shocks. Anyway, the Bilstiens are better in my opinion but the Rancho's are also good. As for tires, I'd go with a 35x12.5-20.

 

I'm running the RS9000 adjustable shocks and I think they're great. Also running the stock 20's with 35x12.5 Mickey Thompson ATZ's. They fill the wheel wells perfectly and I didn't have to cut anything. At full lock the side biters barely touch the lower control arms, but it is only if I have it at full lock and keep the pressure on it while turning, it's so minimal I can't consider it an issue. It's a great lift kit. Fit and finish are excellent, you won't be disappointed!

 

I've had both Bilsteins (with 2" level) and now the R9000 adjustables with my lift and both are excellent shocks. To be honest, I give the edge to the Rancho shocks with adjustable valving as they allow you to better tune your ride especially if you intend to carry a load or tow, etc. But as mentioned, you cannot go wrong either way.

 

What he said. ive put about 2500 miles on my rancho lift with the r9000 shocks so far i really like them

 

thanks for the info. What about the best and cheapest place to get the lift and tires. Thanks again

 

Stovetop, how come you had a rubbing issue with the new wheels, but with the stock 20's you say I wont.

 

It's a combination of width and backspacing of the rims. My old Helo Maxx rims were 9" wide with 5.5' of backspace. The new rims are 10" wide with 4.5" of backspace which pushes the rim farther out past the fender. The less backspace you have, the farther the outer edge of the rim will be (relative to the centerline of the rim). The outer edge of the tire rubbed when turning the wheel to full lock. The extra 1" of lift allowed the tire to clear.

See a similar thread: https://www.f150online.com/forums/su...ancho-4-a.html

Someone correct me if I am wrong, but your OEM rims are only 8" wide with close to 6" of backspace. Therefore you should have no issues with the tire rubbing at full lock, as long as you stick with a 35x12.5 tire.

Hope this helps!

 

Pretty close, the OEM 20's are 8.5" wide. Just want to clarify that in case the OP is looking for tires within the approved width range.

That would be the same combo I'm running... As StoveTop said you won't have any issues.
