I'm looking at replacement shocks for my 2017 ram 1500 quad cab 4wd. The truck has 20" wheels and according to the build sheet, has a factory 1" lift. Does that mean the 4600's wouldn't be the right fit and I should go to the 5100's because of the lift?

To the best of my knowledge only the Rebel and Outdoorsman models have a factory one inch lift. I have a 2018 crew cab BigHorn with 20 inch rims and no factory lift. The 4600 series is a replacement strut and shock that is designed for standard factory replacements. If you are interested in leveling your front end up to 2.5 inches higher the 5100 series is what you want. If you are keeping everything stock height the 4600 is perfect. Again I do not believe that any model except the Rebel and Outdoorsman employ a factory lift. Your build sheet may state a factory one inch lift because of the larger rims and accompanying larger circumference tires. You can reach out to Nick@gotexhaust who is a preferred vendor on this forum who specializes in Bilstein shocks for a more definitive answer or contact Bilstein directly.

Yes. You can set them as high as 2.1” without needed to upgrade upper control arms. Or if you want to keep it stock, the second lowest snap ring on the 5100s (0.7”) is what you’ll want

I've been running with 2 3/4" spacers and stock shocks since 2016 and have had no problems. I have a set of Moog upper control arms and Billsteins on the shelf waiting for signs to be replaced but it hasn't happened yet.

The old , if it ain’t broke don’t fix it comes to mind. That said I’ve been running Bilstein 5100’s set at 2.1 since 2019 and absolutely love them. They cured the rear end “hop” over rough patches while turning and slightly stiffened up the ride which I prefer. I stayed at 2.1 so I wouldn’t need angle correcting UCAs although I did replace the OEM UCAs with the standard Mevotechs due to the sketchy OEM ball joints on the factory setup. Very happy with the Bils.

Thanks all. Don't want to change anything from stock ride height. Concerning the build sheet, it says "raised ride height" on the next to last page. From what I've read in the forums it's a 1" lift from the factory .

I'm leaning toward getting the 4600's if they'll set up the same. From the pics online of them, it looks like they have 2 circlip positions, presumably for either factory position. I emailed Bilstein last week about it, but haven't heard anything back.

If your truck stays mostly on pavement you’ll probably be happier with the 4600s, I’ve never had them but I hear they are softer then 5100s.

Pretty sure your assumption on the circlips is correct, pretty sure I’ve read the same thing elsewhere but can’t find it now. The 6112s and 5100s have a printout sheet in the box that shows the correct setting for each model/desired height but I also couldn’t find any such thing for 4600s

Yes, mainly on pavement and do quite a bit of towing a 6500 lb travel trailer.

Just an update. I got this reply back from Bilstein in case it helps anyone else looking at these:



"In the interest of clarity, I have pasted your questions below and written my answers beneath them. Thank you.

It looks like the 4600 front struts have 2 circlip positions on them. Is this correct?

I assume you are referring to part number 24-317894, this product does have 2 circlip settings.

I'm assuming the lower one is for the factory standard ride height and the upper one is for the factory raised ride height. Is this also correct?

The lower setting is for stock ride height and the higher setting will provide .7” of lift through spring preload. Maintaining the same ride height you have now will largely depend on how RAM lifted your vehicle from the factory. They likely used a slightly taller than stock coil spring to give you the lift instead of a taller setting on the shock. Ultimately you would want to lay down your OEM shock next to ours and compare the spring seat height to pick the correct setting.

Also, is there any difference between the 4600 and 5100 series shocks other than more ride height adjustability with the 5100 series?

The 5100 series is slightly taller than stock to accommodate for being used at the higher lift settings. Besides the length, the coating and the amount of grooves, they are very comparable products.


I'm leaning toward getting the 4600 shocks unless there's a reason I should go with the 5100 series. I frequently tow a 6500 lb trailer.

If your vehicle is stock ride height we would highly recommend our B6 4600 series. They are considered by most to be an upgrade in comfort and performance over the OEM system and provide superior handling and control when towing. At stock ride height they are our best riding and longest lasting damper. There is a lot of misinformation online that suggests our 5100 series is stronger, better or more heavy duty than our 4600 series. Nothing could be further from the truth. Both are made out of the same high-quality materials; the biggest difference is the coating and the fact that the 5100 is physically longer to accommodate for a lift."

awesome, I have used both on current and previous trucks, 4600 was the firmest out of 4 4x4 shocks I have used, the 5100's are the least. But that doesn't tell the story, it projects as least firm because it allows for the most travel, so even though dampening is the same, the travel makes for a better ride, assuming you are at 2.1 or 2.8 setting. The other shocks were rancho and kyb red tube, for me the best OEM size shock was kyb, but the best shock by far was 5100. Rancho and 4600's very similar and I did not prefer the ride, and I like firm rides. They are firm and feel dead when the hit bottom rancho/4600, whereas kyb's had some bounce to them. I liked them better then gushy OEM, but not much.
