What’s needed for a 4 inch lift?

Hey guys,
I know this question may seem stupid but I just need someone to dumb it down for me. I’ve had my taco for about 4 years and have a 3 inch Billstein lift but it’s about cake now. I plan on keeping my 1.5 AAL in the rear and would like to go an inch higher up front. What all would be needed specifically?
I don’t plan on doing a spacer lift, and would appreciate some strong coils to compensate for my heavy ass bumper.
Any specific suggestions/links would be great!
Thank you guys so much!

edit:
I have a 2011 Tacoma prerunner. 305/65/18’s
Adjustable Billstein lift with heavy duty coils (I think toytec?)

 

Is the truck 2WD or 4WD?

You aren't getting 4" of lift on a 4WD truck without going to a drop bracket lift. Your CV angles would be too extreme to get that much lift with the lower control arms and front differential mounted in the factory position.

On a 2WD truck, you can do lift spindles. Those are a great option because you gain a lot of clearance (drop bracket lifts let you fit bigger tires, which will gain you clearance, but the lift itself does not gain significant clearance because of the drop bracket). You can't do lift spindles on a 4WD truck because of your CV axles.

4" up front and 1.5" in the rear is going to be bro raked like a mofo. You can add a 1" block with that 1.5" AAL to level things out a bit more.

Your best bet is to just replace your worn out coil overs up front with something with the appropriate spring rate for your heavy front bumper. I'd go with old man emu.

 

Spindle lift on your prerunner

Call Marie @HeadStrong Off-Road and ask about the @ChadsPride special

 

A total waste of money and time.

Camburg spindles paired with aftermarket UCAs and 2.5in coilover set. Boom.
Set coils at 0", smoothes ride of your life at 4in lift.

 

Truth, the whole truth and nothing but the truth.
