351-893HD (top) vs 351-893XHD


Installed the xhd set today, ended up also putting my front 5100s to the 3rd notch (+1in) to offset the rake from all the height gained with the new springs.

My current stats are:
F- 37 7/8”
R- 40 1/2”

The xhd drive exactly the same as the hd springs did, which blew me away. I expected them to be stiffer. Well see if I screwed my self with the added height in the front, but i suspect it will all work wonderfully.

I'm probably just too tired tonite to focus; but I read this entire thread, and I'm kind of curious. Which of the springs would you recommend for a little more control while towing, but without raising the rear (too much?)? And it sounds like you also installed shocks in the front if I read that correctly?

So I'd like a little more towing control, but also like the stock unloaded feel and don't want to mess to much with ride height.

I've sworn off other suspension helpers like sumo springs/timbrens and air bags, tried them, done that, didn't like it; but I might gives these springs a shot.

I would think the 351-893HD would fit the bill. I'm running the Air Lyft 1000hd bags with 10ply tires and a weight distribution Hitch, and my truck handles our 26' travel trailer great with the factory springs. Our travel trailer has around 600lbs of tongue weight.

I also recommend 351-891HD or 351-893HD. Ive run both.

Both made the ride a LITTLE (intentionally emphasized) stiffer, but really not at all. The truck rides like a dream unloaded with all three sets ive run so far. I routinely drink coffee from a regular open top mug while driving, and the upgraded springs haven’t stopped me! The hellwig makes more impact on stiffness than the springs did for sure.

My TT has a DRY tongue weight of 715lbs. I estimate 750-800 as it sits loaded. Which is honestly heavy for the 1500, within its capabilities, but heavy.

The 891s gave me 1/4”-1/2” of lift in the rear. It was COMPLETELY imperceptible while looking at the truck and driving. With a WDH i was dead even front to rear with my TT.

The 893s 1”-1 1/4” raise in the rear. A little more noticeable to the eyes, but I couldn’t tell while driving. I sat 1/4-1/2” high in the rear with the TT with these.

BOTH sets handles the camper WAYYYY better than the stock springs.

I do have Billstein 5100s on all four corners. Pretty much just because I could and assumed I would end up where I am now, using the 5100s to lift the front to compensate some. They are definitely a little stiffer than stock, but I prefer that feel personally. If you want stock feel id suggest sticking with the oem shocks for now and see how the springs do ya.

Overall Im beyond pleased with these cargomaxx springs, and i know you will be as well. Get some sleep and re-read through the thread to be sure you’re tracking all the info. Its been a heck of a ride experimenting with these. Thankfully these springs are relatively inexpensive enough that you can try one and if you dont like them..try another.

Im excited to see how my current setup does with the TT. Im loving the look of the truck with the 1” lift in the front and the 893XHDs in the read.

^^^Here is where Ive been getting the springs.^^^

Youll find them under the 2018DT rams, but they fit the newer DS rams perfectly.

@Gren71, did you replace your upper control arms when you installed your 5100's ?

@Gren71, did you replace your upper control arms when you installed your 5100's ?

Nope. Stock as heck. I have the the 5100s set to the 3rd notch which is about 7/8th inches of lift. As far as I know they dont need replaced until 2in or so.

First pull with the new set up

351-893xhd

No weight-stock front
F-37
R- 40 1/2
(3 1/2in rake)


No weight - +0.9” front (3rd notch)
Day of install
F-37 7/8
R- 40 1/2
(2 5/8in rake)


1st hook up @ storage
F-37 7/8
R-38 7/8
(1in rake)


After drive home
F-37 7/8
R-38 5/8
(3/4in rake)
(1 5/8in of drop)


No weight, after unhooking
F- 37 7/8
R- 40 1/4
(2 3/8in rake)

Overall the springs drive amazing, and feel great with the truck.

But im a bit let down with the minuscule improvement in rake. If it maintains 1/2in of rake after a trip ill probably be content, but i have a habit of not leaving well enough alone

Im wonder what height the rear sits with the 351-905xhd springs

Unloaded

Looks pretty awesome from the pictures.

Do both the 891 and 893 HD's have a tendency to slip out when the axle is dropped down? Only reason I haven't pulled the trigger yet, kinda worried that this might cause issues down the line.

The 891s would go loose at full drop on a lift, but my shop never reported them coming out.

The shop has said the 893s stay in place. And I can verify that as I had to tape my upper spring isolater in when i installed both the 893hds. When i just swapped them out the tape was in the exact same spot. Which to me means no one has messed with it.

I'm (obviously) completely green when it comes to aftermarket suspension. How do the 5100's work when it comes to raising your front end? You just need the shocks themselves, no other hardware to lift the front a bit?

I'm thinking I might go 893's and get a bit of unintended lift in the rear, I'd want to match that increase somewhat in the front as well as I don't want too much rake.

The 5100s have the ability to be set to anything from stock height up to 2.4in if memory serves. There is a ring system under the bottom plate of the shock that allows you to adjust it. You are also able to take them off and change it, like i recently did, if you want more or less front lift.

And if you’re after 351-893HDs ill be selling mine since i went up to the XHDs.

The combo of the 893hd rears with the front 5100s set to either 0.5” (2nd clip) or 7/8” (3rd clip) would look fantastic

Like I said..i cant leave well enough alone.

Went out today to mess with the WDH since now the ball is more that 1” over the top of the trailer coupler…and equalizer wants the top of the ball level or up to 1” over the top of the coupler.

It got dark so I had to stop but now that I raised the front im just not sitting exactly how I want. I have a trip this weekend and i anticipate the nee springs will settle to where the truck is nearly perfectly level, where i want it to settle and have 1/4-1” of rake, while keeping the trailer level and my front end close the normal height once the wdh is engaged.

Sooooo

I ordered the 351-905XHD variable rates

2019 - 2023 Dodge Ram 1500 Rear Extra Heavy Duty Variable Rate Coil Springs

General Spring provides heavy duty rear variable coil springs for 2019 - 2023 Ram 1500, 70% increase. Meet your needs with us today!

www.generalspringkc.com

They’re only 1/4” taller than the 351-893XHD i have in now. But the spring has a larger diameter so should (god willing) handle the weight a little better and give me what im looking for.

For reference since this get buried in long threads, or across multiple on the same topic.





My stock rear was 38” ground to bottom of wheel well.

With the 351-893xhd its 40 1/4”

This info shows the 905xhd to only be 1/4” taller which should put my
Rear at 40 1/2”

Front-37 7/8
Rear- 40 1/2

Potentially giving me 2 5/8” rake. Which will work well.

I'm glad I'm retired and don't have a lot of money to play keep up. I do plan on eventually going with the HD'S and bilstiens. I was planning on being up in Moab this week with a bunch of tjwrangler forum members. They're doing harder trails and breaking things. Fortunately I had to stay home and have our master bathroom remodeled. I think I'm ahead?

You sure do love uninstalling/ reinstalling springs huh

Honestly, I blame being a Jeep Owner. I always feel the need to do something to the vehicles that I own. Thankfully, these springs are relatively cheap in the long run and once I get this dialed in for towing, I’ll go back to working on my beater car.
