What is the best lift for performance, trd pro or 3" Toytec BOSS kit

I have a new 2016 DC Tundra sr5 trd and have already started upgrades. I just ordered the pro gril, i have a sprayed in bed liner, borla dual exhaust, step rails, and was looking at the trd pro shocks kit for it.

I wanted to keep a good ride and was told the trd pro shocks were very good both on and off road. I was also told it would be better to get toytec tundra boss kitt.

Thanks Sean, Do you have a part number i could use. I would like to do some more research. Also did you paint your bumper or is it a wrap. I wasn't sure of the cost there as well.

 

For the price of the Tundra TRD pro suspension, you can by a fully adjustable fox setup front and rear that will provide a much more tunable ride.
That what I did, and I love it

 

Check here:

 

i'm sure the boss system for the front is a decent kit and would be an upgrade over the ride of a stock system. one thing i wouldn't do again is use an add-a-leaf to lift the rear of my truck as it just became squeaky over time and was too stiff to be enjoyable.

 

coachbuilder's shackles/bushings are what i'll be using once i get things going with my truck.

 

When considering using shackles for lift, you need to consider, if you ever put a heavy load in your bed on a daily basis or ever tow anything of substantial weight, you may want to go a different route from shackles. To me , IMHO, shackles are nothing but bling to achieve height. (but not as bad a a block spacer for rear lift.) Shackles put a "pre-load" on the rear springs just like spacers do on front coil overs. It all depends on your use.

 

Shackles were made for this lift look (and these suck, not the right "look"), not necessarily for 4X4 suspensions:

 

What's your dog trying to get into?? Lol

 

Not my dog. This pic is from a Google search to show how lame shackles are. After a closer look at the pic, I see what you are talking about. Hoo Wee!!!!!!!!!!!!!!

Edit: You can tell from the pic, if you add shackles for lift on a heavy Tundra rear end, the OEM rear springs will have a lot of pre sprung weight before you add anything like a heavy camper (if you have 6.5' or the rare 8' bed) or have a lot of tongue weight at the rear. Springs can actually become a safety issue if improperly loaded with shackles. A fact, unless you upgrade springs to compensate for the negative effect shackles have on pre loading.

 

Lol! How's the weather...... Nice BUTT could rain....

 

I kind of wish the dog in the pic was mine.

 

the only thing i haul with my truck is an aluminum 10' trailer with my outlander on the back so the tongue weight is fairly minimal. also, for the 1" i'm aiming to pick up means a fairly minimal shackle will be used.

 

Shouldn't be a problem at all. "Add A Leaf's" aren't a bad way to go either to gain an inch lift. Fairly economical too. Coachbuilder makes very decent shackles. Several here use them. Very beefy:

 

I don't understand how you say that a shackle puts a pre load on a leaf spring, it's really not even comparable to a front coil over setup. A spacer placed above the strut assembly also does not place a preload on a coil spring. You only place a preload on the spring if you place the spacer above the coil spring within the strut/coil over assembly.
As for lift blocks, they are far worse than a shackle lift as they change the pinion angle and cause the rear end to be more unstable.
Coachbuilders shackles are probably the best way to lift the rear of your Tundra from 1-3". Please explain to me how a shackle lift will affect the pre load of the leaf spring because that I haven't heard before.

 

i do have some experience with an add-a-leaf as i had one in my tacoma and in all honesty i wouldn't go that direction again. the lift was fine but they fell to squeaking on almost any bump and removed any plush ride that i previously had. shackles seem like the perfect solution!

 

Not all add a leafs have the same spring rate. Some mfr's sell cheap "one size fits all" AALs. Like anything else, AALs should be matched for the setup you are trying achieve. With properly installed AALs there should not be any squeaking issues with dampers utilized between the leafs. I've seen some guys use the shackle with AAL setup. It all depends on your needs, preference, past experiences too. The main thing is to get what is best for you. What you want.

I agree with the statement as far as spacer placement on front coil overs. Mounted below there is of course preload. Above ,no preload but you will still have possible suspension travel limitations.Most shackle setups will not cause any issues at all. A leaf spring can be preloaded just like a coil spring. Totally comparable. Any spring type can be preloaded. Simple physics. Too long of a shackle without compensating the rear leaf package (from OEM setup) can and will cause a preloading effect just like the spacer mounted above a coil. Have you ever loaded a lot of weight to the rear of your truck to the point your leafs flattened out or at least have seen it? I've seen so much weight added to where the OEM rear leafs bent down to a transverse position. Not good. At that point not only unstable but down right dangerous to everyone on the road. Similar to transverse spring packages used on hot rod setups, except the difference is that transverse springs are made that way, not forced to that position which can be a serious safety issue. If you use too long of shackles and you from time to time haul heavy loads, the rear leafs reach the flattening "out" point sooner due to the preload from shackles being too long. Like I said, most will not have a issue. Even shackles reach a point from being very efficient to problematic at a certain point like spacers. Your individual needs/usage need to come into play with any front,rear suspension setup.

 

I'd just like to hear a good explanation as to how a shackle increases the pre load so that I can better understand.
As to keeping the leaf spring from maxing out, I run Timbren bump stops/ load assistance to keep my load capabilities at their best.

 

As you know some folks get carried away at times for the "look" without considering what else could come into play.. You clearly know what you are doing. I'd like to add the Timbren setup you have at some point. If you think about it, as soon as you increase the length of a shackle you are raising the bed and at the same time pushing down the rear of the spring. Maybe only a little preload . At a certain point the preload will become more pronounced (or noticeable) as shackle length increases to a point where you would want to compensate for that. By the way, could you post a pick of your Timbren setup if you get a chance? Definitely a good way to go for those of us here that may tow or haul the occasional heavy load.

 

From what I understand what would affect the pre load on a rear leaf spring is changing the distance from the mounting point at each end of the leaf spring.
Here is a picture of a Timbren setup on a Tundra.

 

Coachbuilders +1 on the left, factory shackle on the right, for those wanting to add about an inch to the rear and level out their truck I'd highly recommend these with Coachbuilders urathane bushing kit for the leaf spring. This is a much better way to add the height to the rear than using a block lift. These things are built impressive to put it lightly!

 

Thanks for the Timbren pic. Yes, changing the mounting distance between both ends puts an equal +/- load affect at both ends depending whether the distance is decreased or increased, whereas changing the geometry on only one end will at some point become less than desirable. (Rarely). The Coachbuilders are definitely nuke proof. I would certainly like to swap a pair of those in to replace my factory shackles. I have enough lift already. I wonder if they make them OEM length or maybe for 1/2".
Not sure what happened here:

 

The shortest ones they make are the plus ones, which add about 3/4" over all height to the rear of the truck.
The reason the lift shackles don't really add much of any preload is because they have a secondary pivot point at the frame itself, so they are not changing the distance from one mounting hole to the other on the leaf spring itself.
Leafsprings can break, to much weight can be a major cause, also time and use, it's a piece of metal after a certain point and repetitive use they will loose their elasticity. Your safe going with the Coachbuilders +1 I would highly recommend doing the urathane leaf spring bushing swap they make while your at it.

 

The leaf spring in this picture is more than likely on a Tavel trailer based on the electric drum brake assembly and the straight axle, and the one last clue that I can see the black liner they typically use under the floor of travel trailers to seal things up.
Travel trailer manufacturers are notorious for using the cheapest parts they can to cut build cost. More than likely those where a cheap set of low quality metal springs made in China from the get go.

 

I'm going to add the Coachbuliders to my list of things to do this spring along with UCA's. I need to refill my money tree over the winter.

 

Wise choice! I can also speak for the Camburg control arms, they are ultra well made.
Plant a couple money tree seeds for me lol
