I'm so frustrated with my new Fox 2.5s.

I would guess that it takes more weight to compress them so he wouldn't have to crank down so much in order to get the lift he wants.

 

Thank you for responding. It’s rare for me here. I’m having challenges with my fox 2.5‘s I just had installed as well and I’m trying to learn from this thread. I would start my own thread but I fear no one will respond. Usually the senior membership just says to go online and do research.

 

Boom. That might explain it

 

Nope, same part #. The 880 is the Kit part # because they come in pairs. The 980- is the single unit designation.

 

If he’s got that much weight and sag on the 600’s, a high spring weight is definitely going to give some extra lift.

 

I think you all are missing the point. He's maxed out his lift because the distance from the top hat to the lower shock eyelet is at nearly 21". He's not limited due to coil bind, which is the limit of the lower spring rate. Yes, it will compress more under dynamic loads, but that's not what we're talking about. He's saying he's only got limited lift while sitting in the driveway. There's something amiss with his measurements (I believe).

Whether he's at 20.75" (top hat to lower eyelet) with a 600 lb spring or a 2000 lbs spring, it's not going to change the ride height while sitting still in the driveway.

 

I cranked it up to 21 1/8th like they said and I am now getting the proper lift but the preload is too much so Im thinking I need more spring.

 

Right now im at 2.3 inches of lift on the drivers and 2.5 on passenger but the ride is too stiff.

 

Here's some super high tech diagrams to explain. Note that regardless of which coil used, it will have to compress more or less to support the weight of the truck... but regardless of coil choice, the shock length at rest will be the same.

The only limits to this is coil bind. If you compress the coil so far that the coil rings contact each other, that's no bueno. Also, a lower spring rate can be too squishy, leading to excessive body roll or nose diving while under dynamic loads. But neither of those issues were reported by OP.

 

then why do 3rd Gen front struts give a 2nd Gen 1” lift in the front? They are clearly not the same


So much bad information in this thread. Wow.

 

this is the answer.

I had bought ADS front coil overs for my truck and had this same problem. 21” from the top of the strut to the middle of the bottom eyelet and only gave me exactly 2” lift in the front. Even with 14” 700lb springs.

the only strut that is actually designed FOR the 3rd Gen is the Eibach pro-truck struts.

Everything else was designed for 2nd gens and they just so happen to fit 3rd gens.

When these manufacturers claim 3” lift , it really means 2” lift on 3rd gens and 3” on 2nd gens.

 

Right now im at the lift I want. I have the shocks at 21 1/8th inch which accutune said would be ok. 2.3 inches on the drivers and 2.5 on the passenger. The problem im getting now is the ride is very stiff. So I think if I get a 650 coil then I can maintain the height but smooth out the ride with less preload.

 

You really should consider keeping 600 lbs springs but get a 14 inch spring vice the stock 13 inch. If you are complaining about a rough ride now, a higher spring rate will make it worse.

 

vehicle weight is different which is why a 3rd gen shock lifts a 2nd Gen more. Geometry is the same

 

Ok i see. Im going to be adding more weight to the front too. Maybe 150ish pounds. Should I go 14 inch 650lb? I might even go dual batteries some day as well.

 

I’m still trying to tell if you’re trying to argue with me or if it’s a legitimate question.

The simple newer is your paying “big dollars” for the product, which is standardized for large qty manufacturing.

What everyone fails to realize is that the vehicle setup is subjective to each application and preference. There’s too much variation for a “one size fits all.” Even if you buy shocks from a vendor that assists with the setup, it’s very difficult to nail it every time because what you are looking for and what I am looking for are vastly different.

You’re also ignoring the fact that the OPs original question was based on ride height, even though the experts have implied that he’s trying to exceed the recommended “lift,” but now he’s saying the ride is too stiff. You can’t have everything. The vehicle suspension has other limitations to consider.

 

I understand there is no one size fits all which is why there are specific lift sizes and shock/spring rates people buy. Im not trying to exceed the recommended lift. The shocks are at 21 inches per recommendation. The kit says 0-3 inches and so I would think 2.2 inches or 70% of the max height wouldnt be a problem. 3 inches would be impossible for these shocks on a 3rd gen even if someone wanted that even if they didnt care about them being stiff.

Also it being a massed produced product, fox is one of the world wide leader in performance shocks sales wise and accutune is a well respected name in the industry and I gave them 4k and every detail about my truck so get it right.

I have the solution to solve this from happening again. It would be very useful in the description of the item to state 1 7/8th inch ride height max for performance purposes. Or accutune should ask the goals of the rig before building the shocks.

 

If more weight is in the future, then yes, probably 650 lbs springs are ok.

 

I was asking you a legitimate question. Let me put it this way. I know more about the space shuttle engines than I do about suspension systems for Toyota Tacoma‘s and I know nothing about the space shuttle engines. Perhaps that helps.

I would think that at this point every suspension/wheel/tire configuration known to man has been done on this third-generation Tacoma. I would think that at this point it’s known 100% what works, what kind of works and what absolutely doesn’t work. However finding that information here it’s like pulling teeth. I guess what you were telling me is that everybody is still pretty much winging it. If it works awesome, if not try again. It’s pretty frustrating. Please know I have nothing against you but I was asking you if you expected him to go above and beyond what the lift shop is telling him and it looks like you were. It also looks like that’s the only way he’s going to find answers. It also looks like it’s the only way I’m going to find answers. It sucks. Anyway thank you for your response.

 

Well put. I agree 100%.
