Suspension Questions: Bilstein 4600 vs 5100 vs Coil-overs

So I am hoping to level (leave back stock height but new shocks) my truck next year and need some advice. I currently have the standard shocks with the TRD Off road package (2015 DC) which I believe are the 4600s. I feel like every bump and road imperfection is jarring at speeds above 40 mph. This especially blows driving 70 miles a day. My budget is $1200 installed. I think I have a couple of options:

1. Upgrade to 5100s all around (middle setting in the front, leave back stock height). This meets the budget but I have read that the 5100s are almost the same as 4600s so I think the ride quality won't be much better.
2. Upgrade to 6112 in the front (1.9" setting) and 5100s in the back stock height. This might work but I think it will break the bank. I could probably handle the rear install to save money if this really is the best option.
3. Upgrade to Fat Bobs Coil-over package with 5100s in the back stock height. I have read mostly good reviews but not that many people have this package. This is probably right at the top of the budget.
4. Upgrade to Old Man Emu coil-over package fronts and rear. This looks good but I think the truck will be lifted more than I want for the amount of miles I will be putting on. I did not want to have to add a shackle or block in the rear. This will probably be over budget installed.
5. Eibach front coil-over package (set at 2" to level) with 5100s in the rear stock height. This was my top option but I recently read of a lot of people having issues with these coil-overs. Not sure if this has been resolved at this point.

Also, I live in NE PA and know that some of these packages do not handle the salt/winter combo not as well.

Thanks in advance for all your wisdom!

 

Old man emu with 612 springs if you are keeping your factory bumper and toytec adjustable shackles set at 1 inch, seriously for about $1000 plus labor, or no labor if you install yourself, you get a pretty impressive ride and handling. All depends on how you want to use your truck.
For me the OME worked out great, highly recommend them

 

No other opinions? BUMP!

 

Based on what you said about the bumpiness, I’d go 6112 for budget, and I also noticed less bump using Toytec shackles mainly due to the new poly bushings that optionally come with them. I think you’ll find 5100 feel the same as what you’re experiencing now, they’re less beefy than 6112 and you’re still using the stock coils. 6112 replace shock and coil.

 

6112 front, 5100 rear, because that’s what I’m in the middle of doing.

I installed the rear 5100’s last week. Ride feels much better than the 11 year old 4600’s that came out (still have gas pressure and dampening when cycled by hand). Front kit is backordered for another month or so.

I knew the fronts didn’t come with the top hats and bushing, but was disappointed to find no upper bushings / washers with the rears.

I used

$20 Gabriel 143340 Suspension Mount Regular

Gabriel 143340 hardware kits for the rear, and have 143339 top hat kits for the front.

 

What did you end up going with? Sorry to bring up old chat, currently in a similar situation

 

Casting for for 5100 rear 6112 front, because that's what I'm doing right now too! 5100s went in the rear already, improved ride feel and a little less bed bounce. 6112s to go in in the fall with new tires and alignment.

 

I ended up with the Eibachs (not the threaded version but the pro-truck shock that has a ring for multiple heights) on my 2014 Doublecab.

I then bought a 2016 Crewmax, upgraded to Ironman FCP fronts (6112s had crazy lead times) and Fox 2.0 rears. I HATED the Ironman FCP shocks and would not recommend them. I ended up swapping them out for the Eibach pro-truck shocks again because I liked them and they were inexpensive.

Now I have a Sequoia and I plan to keep it stock suspension wise for awhile as I like how soft it rides and the fam is happy.

You still running 6112 and 5100? If so how do you like them

 

$1200 installed with alignment...your only choice is monroe shocks with all old hardware.
install easy run you 500, good alignment is around 120, that only leave you with 580 for parts...no tax or shipping.

 

I am. I’m happy enough with them overall, but my socks aren’t blown off by them either considering that I spent about $1700 CAD.

Two years with no leaks is a good thing, and they do ride better than worn stock 4600’s. They are better at soaking up the big bumps than little stuff.
