Help with a new shock or coil spring

Howdy!

I have a Tacoma '06 Double Cab 4X4 it recently turned 100k miles. Since I bought it new 10 years ago I took it to the dealership every single maintenance date. I just decided that I'll start my own maintenance instead of taking it to the dealership. Cleaned the Throttle Box, changed Air Filter, spark plugs, Front and Rear Diff, Transfer case Oil. One thing I noticed is that the front of the truck is lower than the rear.
I wanted it leveled, will changing Coil spring and Shock do the trick?
I did a lot of readings here in the forum and mostly read about Bilstein 5100, will this help by changing just the front to level out?

Thank you for your help!

 

You could use either a coil or 5100s.

But with 100k miles, I wouldn't bother. Your rear leaf pack is haggard and will need replacing before I'd bother trying to level the truck, since those leafs are so tired and sagged out.

 

I have never hauled heavy stuff on my truck. From the last time I checked the leaf springs it still not sagging (yet). But since you mentioned the leaf might need replacement due to mileage, would installing a spring helper deviate the possibility of sagging in the future? Or maybe AAL would help? I don't want to spend money for that now.

 

I'd spend $50 on a single AAL for the rear.

I'd also use 5100s with your stock coils up front.

 

I have 2015 DC, I also just want to raise front end to be level with rear. What is the best way to do this?

 

Coils.

Cheapest is 5100s.

Spacers are cheaper still but I wouldn't bother.

 

What coils do I need? and what is cost? I don't do much off road driving, I want to keep ride smooth as possible. Thanks for your help.
