I've heard that if you wanna go over 4 inches on an IFS that you have to go with a straight axle? Cause I've got an 86 and I wanted to do a 4 inch with a 2 inch body lift

 

They don't make any lifts kits that I know of that's over 4". A bracket lift should not effect the performance of a suspension lift, so your plans are fine. An SAS would be a lot better than a bracket lift, but I guess it's all on what you plan on using it for.

 

Many bracket lifts are frowned upon, like lift blocks are, because they don't include enough design for safety. They have potential to give 4-6" front lift if you crank the t-bars with it. In general, there really isn't any need to go this tall with IFS since many larger tires can be fit on 1-2" lift and some careful cutting. Search and read up.
Personally I would save up and do a SAS before wasting money on bracket lift and body lift.

 

Theres nothing wrong with a bracket lift. It just depends on what your doing. A SAS is a lot more involved/expensive

 

Maybe I should just clarify that not all bracket lifts are built equally. Do your homework if you decide to install one and make sure to get a good one that takes proper bracing and other factors into consideration besides simply making your rig taller. I will also note that many of the older lifts have been phased out of production because of these issues, and most being sold today have been redesigned from their older versions.

 

Then you should be fine. Why do you want so much lift though? Pretty large curbs at the local mall?

 

Start looking at long travel too. If you want to run IFS, LT is definitely the way too go, very smooth, plush ride compared to a bracket lift, only 3"s though on the lift.

Nate from Blazeland runs a bracket lift and his long travel that I believe could do about 6-7"s (4" bracket + 2-3" LT) or so of lift.

The bigger question is what year is your truck and how big of a tire do you want on it?

 

Yeah, I run a combo kit on my 1986 4Runner. Long Arms provide the travel and the drop bracket provides the lift. All said and done its a 6" lift at ride height. This combination is perfect for 35s. No body lift needed but I have a 1" BL from before that I never removed. I know of a dozen guys running the combo kit and it works great!
