The old one wasn’t seven months old, but the left side of the F250 seems to take more of a beating than the right! Replace left side for softer feel
Reviewed in the United States on November 3, 2024 by Toddman
Great product and happy I went with these shocks. I drive a 17 F-350 platinum and started getting uneven wear on the front tires along with light death wobble in the steering when hitting a bump just right. Had the alignment checked by two different shops and both told me it was perfect. I had already replaced the steering stabilizer with factory ford part and still got the same feeling. I decided to get new tires and try these 9000 series shocks out. I tow a trailer almost everyday so I set the shocks to Max to see how it would ride loaded. Surprisingly the ride was a hair stiffer but got rid of all death wobble and felt 10x better on the freeway. Over 10k miles on the new tires and shocks it feels the same as the day I installed them. Tire wear is perfect and all thanks to these shocks. Will definitely buy from here on out

I bought this shock on February 7th and installed it and a few days ago I noticed oil down the side of my truck . the shock had blown I know they say that, they limited lifetime warranty but when I contacted Ranchero they said I had to go through Amazon to cover the warranty my Amazon did a great job and said that give me a one-time replacement so just let you know Rancho does not cover the warranty unless you buy it from them

I put these on my 2017 f250 October 2023. Thought they were great. Update to May 2025. The shocks are both completely shot. Maybe 20k miles on them and 5k miles towing. I would not recommend these. On top of all this the manufacturer makes it very difficult to try and get their "lifetime" warranty. Very disappointed start to finish. Would not recommend. In the end Amazon refunded me for the order because the store no longer existed. This was the only benefit.

Read Carefully. Had to buy 7 shocks to get 4 undamaged. Problem is the shipper & manufacturer's packaging both. Shocks - 5 star Adjust-ability - 3 star (The adjusters freeze up if not adjusted constantly, tears up your hands adjusting and you dont want to do anything stupid like use pliers. I have read guys have had the red adjuster break into pieces.) ***Problem*** This was so f-ed up it is almost unbelievable. Shame on Rancho and Amazon both. I mean you cant make this up. I didn't have "A" problem I had "ALL" problems you can, I think. Spoiler - Bottom line I bought 7 shocks to get 4 un-damaged shocks 1. Starts at Rancho. They only have 1 box for all 4 shock product lines whether no-lift, lifted, and huge lift 1 box no internal packaging as far as support packing. 2. A 0 or No Lift Shock literally can slam around over 6 inches in the box when tipped and shoot right thru the bottom on to the floor or your foot. ( didn't hit the ground but cough it with my foot) I didn't say opening it. I just said taking it out of the brown box and setting it on the bench to open the product box to be clear. 3. All 7 manufacturer product boxes were damaged or destroyed regardless of the amazon brown box condition which was a mix of excellent brown box to half of the box wrinkled up aka accordion, including a single shipped shock came in manuf product box and no brown box it was half wrinkled and heavily tapped on both ends. 4. The only unit that came in product box only and not double boxed came with a fairly good size dent in the middle of the shock where the piston slides up and down internally. I would bet my truck it shot out of the package and was put back in and taped closed. like who wants that. I have an open RMA for that right now. 5. All 7 shocks had excessive tape on 1 end of the box. 3 of the boxes has excessive tape on both end of the shock boxes and still 1 of the 7 shocks shot straight out of the box (caught by my foot) with a wad of tape on both ends. 6. THE DECALS OR STICKERS....... 7 shocks.... Not even 1 usable decal not 1. all of them were wrinkled up like they had been thrown away. But in reality they in a loose product box. that is no big I use wrinkled decals all the time im a hobbyist. But when they wrinkle in the manner they lift off the paper they get dirt on the sticky and wont seat flat or lay properly. All good. I put WP dirtbike fork decals and it looks perfect. No Rancho Pride. 7.None of these ship overnight or available overnight. The fact i can install 4 shocks in 1hr turning this into a 2 week process was literally a baloney sandwich. 8. PERSPECTIVE I hate Bilstein. But this is the steering stabilizer I went with. 1 order 1 unit received product box good condition not flawless but noting to overly comment on. opened package support packing on both ends box was exact fit for the exact item i ordered package was likely able to be dropped over 6ft and sustain NO damage. Rancho fly's out of the box just holding it not drop the box on purpose from a ladder. 9. 1650mi trip from CA to AZ back to CA I love the shocks quality so far. Bottom line I bought 7 shocks to get 4 un-damaged shocks

Amazon has a unbeatable price on these shocks, and I highly suggest them. I have a 2007 F-250 with 48,000 miles. I put Rancho RS9000XL shocks on the rear end last week because I'm going to be towing a 12,000 fifth-wheel trailer pretty soon and wanted the ability to stiffen/soften the rear end as required. When I got the old shocks off, I was shocked (haha) to find the stock Rancho's were completely dead. I figured the front ones would be even deader (Not a word, I know, but I like how it sounds). I got these in the mail from Amazon on Friday, and today (Saturday) they are on and set to 5. The truck rides better than new now! I keep them set at 5 in front/3 in rear for when not towing... I haven't towed with them yet so I cant make a suggestion there, but others I've read seem to use 5 in front/8 or 9 in rear.

I had the dreaded 'death wobble.' It looked like the shocks were original to my 2011 F350 with 125k miles, so I decided to replace them. I wasn't sure what kind of dampening I would need to get rid of the death wobble issue, so I bought these adjustable shocks. Installation was simple with the proper tools, although I wish my socket wrench for the upper bolt was thinner to allow better clearance. You can compress these by hand, if needed to re-position. To expand them during install, turn the top post about 1/4 turn, and it will expand slowly. I did get one without the upper bushings, but I used Amazon's return policy and got what I needed. This solved my death wobble issue, but I also bought some track bar bushings that I am going to install too.

I replaced my oem shocks that were about 8 years old with these and I really can't tell any difference. I wish I had just bought the standard non-adjustable shocks and saved some money.
