Rear spring pack questions

Sorry if these are dumb questions I tried searching but did not find an answer. I have a 2013 Tundra with a 6" fabtech lift, it appears to have a 3" block in the rear. My question is I want to get rid of the block and install a new spring pack so it matches the ride hight I have now and get a better ride. So would it need a 3" spring pack over stock hight or a 6" spring pack? I am guessing a 3" taller spring pack would raise the back 3" and replace the block and match the hight I am in front because the front is typically lower to begin with? Now as far as getting the right spring pack it looks like Deaver is the best but expensive, Alcan is great to maybe a little cheaper, I also saw skyjacker makes a 6" but not sure if that is plus 6" or a total of 6" ride hight and would work. If anyone has any experience with these options and has a recommendation that would be awesome, really looking for a better ride both on and off road and probably install summo or air bags for towing, Thanks in advance for any help.

 

I can help you out here. I have a Pro Comp 6 inch lift with ADS shocks all around with custom coil springs. I eliminated the lift blocks with an 8 pack spring from Alcan. I talked to them about my setup and they did the math to give me the right springs. Due to my truck having the 46 gallon metal gas tank they had to do figure out the best way to counter the weight since it's not static weight, but it changes as I drive. I will say they did a great job. The rear is perfect. I first reached out to Deaver because they have a great reputation. Problem was it was during the middle of the covid shut down. The wait from Deaver was like 6 months, so I called up Alcan and they got it done. I will say this, Alcan did make a mistake with the spring and it was too long. I took some pictures and sent them in, they fixed the problem and worked with me. But it does ride great.

 

If you want a quick, cheap, and easy fix then go with the Skyjacker. It’ll give you 4” of lift and get you to where you are now. They come with bushings but you’ll need to buy new and shorter U bolts.

block height + leaf pack height does NOT always equal to lift height. The Skyjacker pack is about 2.5” tall.

I’m on my 3rd set of aftermarket leaf packs trying to get the right height and flex. At this point I’m just waiting to get my truck to a point where I have all the my daily driving weight and off-roading weight figured out then I’ll go with custom springs but my Skyjackers will do for now.

 

Thanks for the advice guy's here is what I ended up doing. I found what seems like a pretty awesome deal on a set of leaf picks from Ironman 4x4 they are the 0-440 pound set +4", talked to a great guy there who helped a ton, said it would sit about 3.5" which would be perfect. Basically everything is 25% off right now FALL25 coupon code. The packs come with everything you need to install, bushings, New shackles & more $570 shipped! Maybe too good to be true but we shall see, I did read up as much as I could find on their products and they seem legit. I called Alcan & Deavers both $950 and up (just for the spring packs ) depending on what you want....figured I'd give these ironman a try for the price. I am also planning on installing some Firestone ride rite with cradles for towing. Just going to use my fabtech cheap shocks in back for now and probably the Vertex up front and see how it does. I don't usually go cheap but hey its got to be better than blocks in the back!
