Thanks. I was told I need new shocks my front tires are cupping. Any recommendations on new shocks. I’ve read on line the bilstein 5100 are good.

Stock (factory) shocks suck. 2 of my 4 were done at 30k miles. Bilsteins get all the rave around here along with Fox, I think.

I'd use those up front but for the rear I'm gonna go with a regular, non-gas charged shock, probably from zone off road. Did this on my 2014 F150 and it rode so much better. I'm not doing the Baja 1000 in my truck so I don't feel like I need the gas-charged shocks.

I would also have the front end aligned. The alignment from the factory sometimes is off. Especially on duallies.

You have a 5th shock in a steering stabilizer.

thanks for the advice. Helps out a lot. But is there a difference between the 150 and 250 as far as shocks go. I ask cause of the big weight difference

If you have the factory “snow plow” option, the Bilstein 5100 std. works well, otherwise the 4600 series is just right. The reason is the 6,000 lb spring rating vs. the 5,000 lb. spring rating has the front end sitting up more level with the back end. And yes, also replace the factory steering stabilizer with a Bilstein as well.
I caught all 5 pieces on an amazon sale for a little over $400.

I run my 295-65-20 Toyo Open Country Extreme tires at 66lb. Pressure for normal driving and the ride is just what I’d expect from a pickup

If you tow a lot you may also want to consider rancho rsx9000. They are adjustable. Makes a big difference if you are towing a RV or gooseneck.

My 12 had them...I haven’t towed the rv yet with my 16. It only has 9500 miles on it. I may just change them any way.

on the Rancho I’ve read a lot of people saying they leak and go out fast but I guess it’s like anything else there are always bad eggs. But I appreciate you telling something good about them

The OEM Rancho that come on the FX4 package wear out fast. But the Rancho 9000 have held up well for me. Totally different shock than the OEM FX4 OEM shocks

My 16 is a fx4 with Rancho branded Motorcraft shocks....they look pretty but wear out fast..IE bargain basement jobbers.

The RSX 9000’s are another completely different animal. The 5000s are as well.
