Eibach Pro-lift installed

Did you do a before and after measurement… I forgot to.

Nope i slipped up as well and forgot. And i think you said yours is 43. Something” on your measurement now correct? But you have 37’s right.

I’ll measure ground to fender tomorrow.

Mine lifted approx 2.25” Front and 1.5” rear. Will need to check again in another week or two to see if they settle a bit…

Glad someone got a beginning measurement How do you think the ride quality is?

 

[Syclone0498]

Anyone have pics of 1.6 front and 1.5 rears with stock wheels/tires?

 

[WhiteTRX]

The ride quality on the “lift” springs (2.7 fronts & 1.5 rears) is pretty good. Much flatter in corners. Truck feels more solid and just slightly less floaty over bigger bumps. I have noticed, on small imperfections in the road, the truck feels a little squirrelly, just for a split second. I have not recalibrated the height sensors yet. I tried to reset the suspension in AlfaOBD, but it does not seem to have had any effect. Dealer said they’ll recalibrate for $160…I’ll go that route at my next oil change and see if that changes anything. Was considering purchasing the RC kit, just to use the height sensor relocation brackets…someone should come out with a TRX Spec bracket for everyone to use. One that would get you closer to a stock location, between 1.5” to 2” of lift in the front! Heck, maybe even one that had a few holes for adjustment. Sensor relocation options for lifts of 1.5”, 2” and Gieser’s 3”…or, even better and cheaper, replacement sensor rods like the 5th gen air suspension guys use to adjust ride height on the reg Ram 1500’s…just a small, cheap tie rod with ball cups on either side. I would have fab’d one up, but I don’t know the stock location/angle of the sensor arm before the lift…that would solve the issue of a dead battery, necessitating sensor recal again, in that situation…

I agree with all of your consensus I fell the same
way about how my truck feels now. The small imperfections or wash board in the road gives the squirrelly jumping around of the front end, I think I want to take it out on some Off-road to see if it still Has the same effect. And yea possibly the relocation of the ride height sensor might make a difference but I feel it’s the the increased preload of the springs now causing it

 

[WhiteTRX]

Yeah. Probably right! Could just be the slightly stiffer springs. I find it hard to believe that the subtle unsettling of the suspension is from the shocks sensing a discrepancy in height…would still like to see if the recalibration or relocation of sensors or adjustable sensor links could help.

Love the look and reviews of these springs with 37s! As far as performance does the truck feel much slower or the same as with 35s? That's the only reason I haven't made the jump yet. I know bigger tire will make it a tad slower but is it really noticeable I guess is really my question lol

I haven't tested mine vis Dragy since switching to 37s but the DA is way higher right now than when I last tested. My first couple of hits felt slower and didn't spin the tires as much but they are also brand new tires. Yesterday, I hit it a few times and thought, yep, it's still fast. I'm sure 0-60 is off a few tenths but it is still fast especially for a big truck.

It’s really hard to say if it’s the bigger, heavier tires, or the suspension.

The washboard effect that people are mentioning… I thought was much more pronounced before I put the springs on. My impression has been that it’s actually tightened that up significantly. Sometimes the road is just the road… and there are some stretches here that it doesn’t matter what you’re driving, the wave in the pavement is going to cause that sensation.

I took it to the east coasts answer for west coast off roading… Hudson County and the Cross Bronx Expressway… and it handled the terrible road conditions like a champ. Better than any vehicle I’ve ever driven.

I did feel more oversteer today in the rain. It was at tad "all over the place" when I would hit it. It seems like it handled wet roads better before. Maybe softer sidewalls? I haven't checked that. I am running right at 35 psi.

My issue is Springs, Exhaust, and Tires all went on at the same time, so can’t really isolate what is a function of the tires vs suspension. Truck “feels” heavier, more connected to the ground, but that feel could also be somewhat attributed to the louder exhaust sound when I’m on the throttle.

I would say watch all those tyrant videos like from TFLT and you can see how the 37’s affect the performance for a better idea. It’s basically why I’m still rocking the stock 35’s I’m not looking to give up my power. Now when I finally get some real good power mods then I’ll probably go 37 or 38

I still have stocks tires so I have to say suspension for me maybe my alignment isn’t dialed in all the way perfect. Now I’m not saying it’s bad but I can say if I don’t have a hold of the wheel in a couple of certain places by my house it will jump pretty hard now I have only felts this in places where the road is waved up from traffic like 18 wheelers that have caused. Driving down the highway or whatever or like a road change in pavement or height I have not seen any issues.

My alignment is about perfect

Could be the extra weight in the wheels dials it in.

As far as loss of power, a tenth or two off of 1/4 Mile time means very little to me. It doesn’t feel like it’s lost any.

That makes me want to cry, I can't tell you how many thousands I have spent in my lifetime chasing a tenth in my drag cars.

Lol but you are building an overlanding rig… you plan on racing it too?

The extent of my desire to race this thing is to make a few cocky Mustang and Vette owners feel ashamed…
