How to Toyota Tundra 4x4 Toytec Add a Leaf Spring Installation

My truck was riding like a soggy bottom boy so I added a progressive leaf pack to add some height to the rear end and support all my tools. I tried to document the process as best as possible. I hope you enjoy the video.
My truck has a 3 inch Toytec Ultimate suspension lift in the front with Coachbuilder beefy shackles and Bilstein shocks in the rear for about 1 inch of lift. In this video I'm adding the Toytec Progressive Add a Leaf pack for an additional 1.5 inches of lift in the rear.
The truck is equipped with a roof top tent from Go Fast Campers, the Active Cargo System from Leitner Designs, and the Decked drawer system for added storage. The add a leaf pack will help with the extra weight in the rear end.
I travel across the country for work and use the truck as a mobile work space hauling all my tools and it doubles as a place to sleep with the tent.

I watched your video and two others over and over again for like 3 hours yesterday so I could do this to my truck without surprises. Went perfect! Thank you for this video!

[@davidlowe4421]

Great work sir, I really enjoyed your work

[@zachmcbride4367]

Nice truck and thanks for posting the video. Im going to take this project on myself in a couple weeks, thanks for the confidence!

[@goatsinapond]

You got it dude. Get after it. I believe in you.

[@docric]

This is what I’m leaning towards. Great info

[@jakemarlow8998]

Soggy Bottom Boy is the name of my next band! Killer truck, my friend.

[@goatsinapond]

Haha

[@toddhardin7169]

Good job on this video!

[@goatsinapond]

Thanks for the feedback!

[@Juan-VargasJV]

Outstanding video

[@goatsinapond]

Thanks for the feedback. I really appreciate it!

[@miztrusa]

Couple things wrong here, 1st is 2 center springs are suppose to come out because new pack replaces them +1 spring. 2nd removing that plug out of the overload spring takes away keeping ur leaf springs perpendicular to the axle and lastly once they are all together you shoulda C clamped all the springs together to make install alot easier. Jus my 2 cent

[@christophervasquez8743]

Without having to lower the jack under the differential so much, you can lift the other side of the axle up making the side you are working on go down. Great video. I’m putting my add a leaf on tomorrow

[@goatsinapond]

Great tip! Thanks for checking the video out. Good luck with your project.

[@heathaaron3443]

Good lookin truck. Looking to do that and air lift for RV hauling. Thanks (subscribed) have an 08 4x4 crewmax SR5

[@goatsinapond]

Thanks brother. Having the extra rear end support will help you out greatly. I hauled a small trailer before doing the add a leafs and the rear end felt spongy. Now it's much more stable. I noticed a huge difference in my overall ride quality when hauling tools and pulling trailers.

[@docric]

Great video lookin to do the same on my tundra

[@goatsinapond]

Nice! have fun with it

[@HealthSupercharger]

Nice job this will be much better for your work truck. To make it even better you should try to make your bottom leaves as long as possible so that they are only few inches shorter than your 3rd leaf from the top. These short leafs are good but great would be 2 long leaves by taking apart the leaf pack and having a spring shop make 2 long leafs for you and fit them in between your longer leaves or at least make them few inches shorter than the 3rd from top leaf.

[@goatsinapond]

Thanks for sharing that info. I'll keep that in mind for future builds.

[@HealthSupercharger]

@@goatsinapond How did the leaf springs hold up so far? All good?

[@goatsinapond]

@@HealthSupercharger Yea, they are working great. The rear end has a slight rake and even when loaded down with tools stays level / has a minor rake.

[@whitiedred]

I did this on my Tacoma and it looks like yours has the same potential problem. When the overload spring is engaged under heavy load, the overload spring could touch the head of the rivet that holds the new leaf spring rebound clip (front). After having it on for some time now, how does that interface look on your truck (any damage to the overload spring or rivet)? I ended up cutting off that front rebound clip from the AAL, but was wondering if I should have. Thanks

[@colehafner-now]

Great video. Makes this task seem significantly less intimidating. It's all just nuts and bolts! Love those wheels, btw. Which ones are they?

[@goatsinapond]

Thanks for the feedback. Wheels are Fuel Vector.

[@jerrytalley802]

Did you add the springs to just raise it or for hauling

[@7y1er_5pencer]

Great video! Thanks for taking the time to shoot this. I was just wondering... I know you did a toytec ultimate 3/1 level. After the 3/1 level and the add a leaf, what would you say you are at now? Also, what elevation do you think you would be at without all the gear? Thanks again, truck looks great!

[@goatsinapond]

Hey, thanks for the reply and feedback. I really appreciate it. Sorry I didn't respond quickly. I've been MIA on KZbin for a few months. I'm not sure exactly how high I am sitting off the ground. I plan on doing a CV axle boot replacement (mine is leaking) soon and when I get the truck on a flat concrete pad in the shop I'll take some measurements for you.

[@bersonlee]

Thank you for the detail installation video. Thinking about getting the Icon 1.5 expansion leaf pack. How do you like the Toytec so far? Any sagging after a while?

[@goatsinapond]

Thanks for the reply. Sorry for the slow reply. I think you'll be happy with the Icon pack. Toytec is holding up nicely. I carry a lot of weight with the tent, cargo rack, and decked system. Then when I fill it with my tools I packs on even more weight. So far the Toytec kit is holding up nice with no sagging. My truck has a good stance with a slight rake which is my preferred look.

[@olegc6209]

Thanks for the video! Could you please tell what is the name of your bed topper that is installed on your truck?

[@goatsinapond]

I have a Leitner Active Cargo System and a roof top tent by GoFastCamper.

[@jonhelton5226]

Great video and thanks for taking the time to do that. I have a 2017 Tundra as well with bed slide, carpet bed liner, and topper and am thinking about installing the same AAL you did. What size tires are on your truck?

[@goatsinapond]

Thanks for the feedback! With the extra weight having the AAL kit will help you in the rear. Especially if you're hauling any tools. In this video I'm running 275/65. I recently swapped to 35x12.5. The 275/65 fit nicely but the width was a little narrow for my liking.

[@jonhelton5226]

@@goatsinapond How much additional weight do you have in the rear end above stock? I carry a constant load of about 500lbs with gear and topper etc. Toytec was saying these progressive AAL's were not sufficient for that much weight. I really don't want to replace the entire leaf spring with an Old Man Emu Dakar.

[@goatsinapond]

@@jonhelton5226 I'm not entirely sure how much weight but a rough estimate for me is around 350lbs of constant load with a roof top tent, drawer system, cargo rack, and tools. I try to take my tools out if I'm not actively working on a job.

[@HealthSupercharger]

Instead of this kit, go to a spring shop and make them take apart that pack and make you 2 or 4 long leaves.

[@HealthSupercharger]

@@jonhelton5226 just have a spring shop add 2 leafs on both sides and you will be fine. Make them as long as possible, these short ones are not so good.

[@mikebarroga74]

Watching your video nice truck , did you adjust your coil overs yourself to achieve 3” or straight from Toytec installed and no coil over adjustment

[@goatsinapond]

They came from Toytec pre-adjusted to approximately 3 inches. When you buy the kit, Toytec sends you a spanner to adjust them further if you need to.

[@dpeagles]

I have the decked and a topper. I think I may add a leaf. Thanks for the video. Plus I tow a trailer some. How long did it take you?

[@goatsinapond]

I think it took me around 6 hours start to finish. Without filming I could have done it in 4 or so.

[@OdysseyOffroad]

What's your review of this Add a leaf pack? Did it develop any squeaks or noises over time and how do you feel the ride is with it.

[@goatsinapond]

No squeaks over time. It's been on the truck over a year now. I guess you could put some grease in between the leaf packs if you were worried about squeaks. Truck rides smooth and comfortable. I do keep it under a fair amount of load with the cargo rack and tent. It doesn't feel stiff to me.

[@cparkerz2968]

Did you think about replacing your bump stops and adding extended brake line brackets?

[@goatsinapond]

I did but it didn't seem necessary for the amount of lift I have. I've been driving the truck with the add a leaf for 10k miles now and it's doing great.

[@deadlymig123]

Right now i have a 3” lift block with bags and lift in the front. I want to delete the block. Would these and coach builder shackles workout?

[@goatsinapond]

Thanks for the reply. My setup is going to provide approximately 2.75" of lift. You can get bigger coach builder shackles and it will put you right at 3".

[@KevinHuff23]

Aren't you supposed to remove and replace the overload spring with the Toytec/Deaver add a leaf?

[@goatsinapond]

Per Toytec instructions, the overload spring stays. You should pay attention to the direction of the shims if you have them.

[@Chris-L-sr]

So what did you do with the alignment pin for the overload spring?

[@goatsinapond]

Thanks for the reply. I used the vice to press it out. It's not necessary as you have the bolt that runs through the center and when you tighten the u-bolts those keep it in place as well.

[@IronMike777777]

How is your plastidip bumpers holding up? How many months has it been? What kind of weather has it experienced? Thanks

[@goatsinapond]

The rear bumpers are clean with no plastidip coming off. The front bumpers are a different story. I do a lot of interstate driving and that has caused small rock chips in the plastidip. The chips are so minor that you cannot see them unless you get up very close to the bumper. I've driven my truck through temperatures around 10 degrees up to 100 degrees, rain, snow, and minor hail. I got this truck a year ago and the bumpers were painted within the first two weeks of having it so roughly a year with the plastidip bumpers.

[@IronMike777777]

GoatsInAPond Thanks for sharing brother!

[@hmongmeskas7445]

Please post the link you add leaf spring website. Thank you I want to add my tundra too.

[@goatsinapond]

I put the link in the description for you.

[@michaelw1412]

Most Toyotas have a lean to the ds. Especially if you opt for the 46 gallon tank

[@goatsinapond]

My 4runner has it too

[@calvinleangpun8749]

Do you still like your Toytec add a leaf? Would you recommend them?

[@goatsinapond]

I like the add a leaf. It has provided me with the proper amount of rake while hauling tools and the extra cargo for camping. If I could do it all over again knowing the approximate weight of everything I carry, I would get beefier leaf springs all together. My truck is under constant load with the tent, decked system, cargo rack, and tools. When under constant load it's better to get a suspension system geared for that weight.

[@ILC-eo6vk]

I pull a 3,200lb trailer with a 2014 F350 Super Duty diesel. I'm getting insane offers for it and I'd like to get a 2020 Tundra. What do I need for the rear of a Toyota to not notice any drop in the back while towing?

[@goatsinapond]

I'd run airbags. If you do leaf springs and shackles like I did, you run the risk of your rear end sitting up too high when you're not hauling the trailer. Airbags in the rear will provide the extra boost only when you're hauling the trailer.

[@ILC-eo6vk]

@@goatsinapond Thanks!

[@jeovannymeza6592]

How much for this parts and work?

[@goatsinapond]

I'm not sure exactly. I did the work myself so it would be free. Call some of your local shops to find out what they charge.

[@lanceshier741]

I would think airbags would’ve been a lot easier and a lot less work.

[@goatsinapond]

I agree. This worked well for me because the truck was under constant load.
