    Howdy Everyone:


    I am sending out an SOS on what I should do regarding my suspension dilemma. First, off big thanks to the AccuTune and the installer- great professionalism.

    I got my shocks and new tires installed today. Installed were Fox 2.5 (2-3 in lift), SPC UCA and 275/70/18 Falken Wildpeak AT3w. I ended up with the front end higher than the back end. Note, when I ordered the 2.5 Fox shocks, I went with the standard 700 lb spring rate instead of the option of the 500 lb spring rate that AccuTune offered (probably my big mistake). My plan was to simply raise the front end 2” from stock.

    These shocks were set at 3” from the factory. During install, we found that the coilovers limit was ½” in reduction of coil tension. This would equate to 1” drop of the front end to get the 2” lift- perfect right?! Well, it didn’t work out that way. As you can see in the picture, the coilovers are at their max reduction in tension.

    Measurement (middle of hubcap to center of finder well):

    1” higher in the front than the back.

    Let me know if anyone suggest any other measurements that I should take.

    ****

    For some reason, even when the front end was higher than the rear end, there was still tire rub against the skid plate- even cut in the outer tread of one of my new tires. Removed the front small air dams too. Installer sawed off part of my skid plate to fix that issue. I’ve read where people went 275/70/18 on stock suspension with no rub. Just wondering why I had so much rub after everything got dialed in after realignment? Is it because the front end is higher than the rear? Note, I kept the stock TRD wheels.

    Anyway, I am thinking about the possible courses of action to bring the front end down to the appropriate 2 in lift:

    COA 1: Purchase 500 lb springs to drop the front end. I had a great conversation with AccuTune today and they stated that a 500 lb spring should make the front end go down. As I remember right, the 500 lb springs are 1 in longer than the 700 lb springs that I have now. Downside: purchasing the springs, new labor costs to remove and dial in new springs, and reinstall. I may need a realignment done too. Since the shocks where tuned to the 700 lb spring rate, there will be a slight rebound difference when going to the 500 lb spring. Positive: 2 in lift.

    COA 2: Add weight to the front end. Examples would be a wench, bumper etc. Downside: more weight on truck, cost of wench, etc. Positive: Possibly the install cost plus the “front end weight” would negate the cost of COA 1. This would allow me to keep the 700 lbs springs that were tuned for my shocks. Question here is how much weight should I add? I am trying really hard to justify a wench. Haven’t done the math yet.

    COA 3: Raise rear end with a block, leaf, etc. This may seem ideal but it still leaves the front end higher than I want. Downside: front end doesn’t do down. I maybe wrong, but I don’t want create a complication on the front diff (+2.5”). Purchase and install of rear raise. Positive: I don’t have “Carolina Squat” anymore.

    I need help and I am not an expert. Please let me know if y’all have any additions to my COAs above or any if you have other COAs I should consider. Thanks!


    V/r,

    Mike

    I would be stoked on the front and getting a new leaf pack for the rear. +2 and +600 pounds.

    Leave the front as is if you’re planning on adding more weight

    I’ve got 5100s on the top notch on the front with 275/70/18 Pro wheels and at full lock I rub a little bit on the stock skid plate. I plan to replace it with an RCI or TRD at some point and will eliminate that.

    As for your height dilemma, I’d say do what you want to do. It sounds as if you’re not happy with how high the front turned out. So, bring it back down. The quickest and cheapest would be to add a block in the rear to level it back out. But ultimately it doesn’t sound like your too thrilled to go that route.

    Put up pics of the full truck from the side on level ground and pics of the tire touching the truck. Likely a combo of the wildpeaks tread running on the wider side of 275 70 18 ucas and not using any other front lift parts to correct the geometry.

    I have a 17 SR5 crewmax with 1.5 inch $25 Amazon spacers over the factory obnoxious blue and yellow struts and springs and I am 1/4 inch lower in front than factory rear. I have the regular factory steel wheels which are 18x8x+60mm offset (same as trd wheels) with 275 70 18 pategonia ATR tires and I'm about an inch away from rubbing anything with no hacking on it.

    when you state, “Likely a combo of the wildpeaks tread running on the wider side of275 70 18 ucas, what do you mean running on the “wider side”?

    This. Now he's got enough height in the front end to accommodate a nice grill and winch setup.

    pcs make it look more level than it really is. It feels like I’m taking off in an airplane.

    Personally, I’d leave the front and get a custom leaf pack to fit your needs and make the back end buttery smooth. Just my $.02. Oh yeah, upgrade the bushing while you’re in there. Would recommend you do it even if you don’t upgrade the pack

    Airplane takeoff lol climb a hill in a lifted rig then make that statement.

    The pics are quite deceptive but yeah I can see a slightly higher front end. An aftermarket bumper would level you out.

    I mean the tires in the size of 275 70 18 have different widths at the tread. My cheap Patagonia all terrains have a narrow tread. Yours are probably much wider at the tread even though they're both the same size I think this usually means that you need more positive offset wheel to prevent rubbing, but I'm not 100%

    Tundra wheel wells and wheel location geometry are not forgiving as something like a ram

    I like this option instead of putting the dollars into an ad a leaf in the back I would put the money into something like a heavy ranch hand summit or stesl craft elevation, bumper with brush guard

    Just make sure you see how much they weigh first and put that much weight on the front of the truck to see if it drops it down to level or slightly past level to be sure

    Another option is to just throw a cheap rear block spacers on the back until you get to a point where you want to dump more money into the rear end to level it out

    I'm running 295/70/18 on the same toyota rims...I do have bora spacers all around which pushed the tires further out in the wheel well. Have 2.5 toytecs with shims from coachbuilder and 3 inch shackle in back with add a leaf. Add a leaf was not a big expense and needed it to raise the back end...I have about 200 extra pounds in front with my bumper set up.. Call Dave @Coachbuilder1

    I understand what you mean. Thanks for the information. This is why I also kept my OEM TRD wheels.

    Quick fix, just put a 1 to 2 inch shackle in The back and it will level out just fine. I have king 2.5 shocks front and rear with a 1 inch shckle in The the back. 20220226_065509.jpg

    I have to be careful as the fox rears can only be lifted to 1.5 in.

    So I decided to look at the UCAs today. Is only having a finger width between the tire to the closest part of the UCA ok?

    I had spc uca and never had an issue with rubbing. I did change them to total chaos and what a difference. The ride was much smoother and best of all no more squeaking. The spc sucked in comparison. No matter how much i greased them they were never quite after 7 months. I have 35x12.5 tires on an 18in wheel with a +18 offset for reference.

    Was it the bushings making the noise?

    It was both the bushings and ball joint. Since the bushings dont have zerk fittings like total chaos, it made greasing them a real PITA.

    Oh damn, SPCs don't have bushing zerks?! Even my Fabtechs have them.

    Nope. I think zerks on bushings are more common on urethane bushings and not rubber like whats on the spc

    I’m just more concerned on how small the gap between the tire and the UCA- is there any rule of thumb regarding this?
