I currently have 5100's on the middle setting with stock springs. Have had them for about 50k miles, mostly pavement with one trek through Death Valley and some trips to the off road park. I drive 90% on pavement. I wish they had more rebound damping, I'm sure on the low setting they are perfect, but then I'd lose my ~ 1" of lift. And I'd really like 1.5" of lift, but then it will just ride worse.

I'm contemplating the OME lift coilover package (90003 shocks with OME medium springs) from nisstec $626 plus shipping preassembled as a replacement/ugrade from the bilsteins. They have good reviews for ride and yield the amount of lift I'm looking for. Although, this puts me close to the price range of the Nisstec MK84 $725 and Nisstec adjustable coilover $750. And from here you can go Radflos, but then I'd looking to get new UCA's and that's out of my budget and overkill for my uses.

What are your thoughts on upgrade options for 1.5" lift in the front?

Truck: 2005 KC Nismo, rear suspension is Bilstein 5100's w/ PRG shackles on lowest setting.

Thanks

By needing more rebound damping,does the truck continue to bounce after you hit a sharp bump? Or does the suspension feel soft and mushy after hitting a gradual dip?
By going to a lower settings,you are lessening the compression of the spring at ride height making for a softer ride.Is that what you want
but not lose ride height?
Sorry for all the questions but we need more information to determine your best option.

Thanks for the reply. Yes, the truck continues to bounce after a sharp hit. Granted, right now the shocks are fairly worn so it's exaggerated. But, even when new I felt similarly.

If it continues to bounce after a sharp hit you need more rebound like you said.
If the ride was acceptable when you first did the suspension work,then maybe you just need new shocks.
If by going to a lower setting and are happy with the ride than couldn't you just use a spacer?
If you want to get more rebound then purchase valveable shocks.These shocks are more expensive than what you have and will take a lot of experimenting.Not recommended unless you know a shock tuner.
To many variables in the systems you mentioned.They may work for you or again they may not.Lot of money to risk.
I would try going to spacers first.Less than a $100 bucks.
I am no suspension expert by no means. Just my opinion.

Thank you for the insight, less preload on the spring and then adding a spacer, that makes a lot of sense and is very economical!

As an owner of bilstein 5100 front struts I know exactly where you are coming from. Mine are on the 1.5" setting and although most of the time on the road they are just fine, over bumps or gravel roads its horrible. They have very little rebound control as in they violently slosh you side to side. They are rough on down travel and then too soft and uncontrolled on up travel. I have ordered the OME 90003 struts and MD duty coils for my truck for $420 shipped and they are in my garage waiting to be installed along with the matching medium duty leaf springs. I should have these installed in the next week or two and can let you know what I think. Honestly cant be any worse than it is now. I researched everything and landed on the OME package, seemed like the best for what I need. Highway, mountain passes and lots of light offroad/gravel roads. Will see how it goes but I'm assuming it will be decently better

I would measure the height of the truck as it sits now. Put it on the lower setting and measure the difference. The difference would determine what size spacers you will need.You probably New that but just in case you didn't.

I could be wrong but I assume since the OP was going to buy the New struts and coils pre assembled that possibly he doesn't have access to a spring compressor or doesn't want to do the labor himself? That would make lowering the current 5100's a decent pain or expensive if he decides to do something different.

Since he said that his 5100 Bilsteins are on the middle setting, they must be adjustable Bilsteins.
They use OEM springs so they had to be installed.I assumed he did it himself (one reason, he understood rebound).
If he doesn't have a spring compressor, you can rent one cheap.
If he can remove the shocks, it would take less than 10 minutes to adjust them at any decent brake and alignment shop.
Not to throw salt into the wound but either way, it is a whole lot cheaper than $420 with no guarantee it will do what you want.

Okay yea that all makes sense. To each their own for sure, If I had 50k miles on my struts and wanted to change the lift I would probably go ahead and get new struts. The lift and suspension stuff gets confusing so much to think about. Im sure lowest perch and spacers will be just fine for him

I appreciate all the input. Whistler's suggestion of lowest perch and spacers is something I hadn't even thought of. It's an option to buy 5100's again and set them up this way and save some money.

Durangofrontier is correct in that in that I was/am looking for a complete kit to bolt on that would be an upgrade. Looks like he's been down the same path and experienced the same thing. ---> I'm very interested in your review of the OME 90003 with medium coils. Please share your thoughts and comparisons to the 5100's once you have them installed!

I have 5100's on the second to highest position with .5 inch spacers on top. The ride is pretty good, but sometimes too mushy and other times to harsh although I attribute some of this to a larger tire that weighs 60lbs also. Mine have been in for 70k with original springs at 97k currently and it's time to think long term... titan swap?

Radflo's sound cool but I hear they have quirks... I like the stock style of the kit your looking at.

Will someone please tell me the spring rate of a medium OME spring?

Unfortunately,trying to attain a good working suspension in many different conditions,is difficult if not impossible using off the shelf systems.

I know I've seen the spring rates in one of the OME posts but couldn't find it. Very true about not finding a perfect setup off the shelf for multiple uses. I think the 5100 adjustable lift probably satisfies most who use it. I still think it's a great, low buck option that does improve ride quality over worn out stock struts.

If there was only one suspension option for the frontier and it worked perfectly for everything what would be the fun in that? Oh and also for the titan swap people I think Greg has a new front suspension option using bilstein 5100 and the eibach springs for around $600. Should be more reliable than radflos.

I was being facetious,is that the word? The point I was trying to make is that "medium"coil means nothing to me.
When I started building the truck(2007),I never even thought about asking questions on the internet.
I had no clue what the approximate stock spring rate was. I could not start designing anything till I knew that.
Thought and thought about it till I figured out a solution. Once I knew that,along with the corner weights,at least I could give that information to the engineers at King and Fox.
Yes,a heavier tire(unsprung weight)will effect how your suspension reacts. You can compensate for that also.Had to figure out how to determine what that was also.
I had to figure out things for myself besides I like doing it.
The word I was looking for was sarcastic.

Both the OME 607 and 608 carry a spring rate of 480lb/in, only difference is the 607 is 370mm length and the 608 is 380mm in length.

Those spring rate seems low.
I looked over the Nisstec website and checked out those 9003 shocks.
They are non-adjustable,right?
I still don't know what you are getting.
Just read Nisstec description of the 5100 adjustable shocks.Said they are ideal for hauling,occasional off roading with maintaining an exceptional street ride.
Sounds great but look how it turned out.
Personally with the Bilsteins at least you have some adjustability.
I have never used spacers but with stock struts and a small raise would be the way to go.
Ok,I am done ranting.
