How long could I run with a 3" spacer with my ADD? Is there any way to get a 3" lift with add without ruining the cv's or boots? Why cant the diff be droped simply by all of its mounting points instead of just the front 2, so that way a drop would be more effective?

My point is, is anything like coilovers or new a-arms or anything besides a real diff drop bracket going to be better on the cv's?

Unless you've got a custom drop bracket, you're gonna run into INNER CV problems. You hardly ever have to worry about the outer CV boots. Good luck, Wes

People used to run 3" suspension lifts without any problems. Then all of a sudden paranoia set in and everything over 2" requires a diff "drop".

alot of guys run 3" spacers and have little problems. asside from the occasional torn boot, it shouldnt happen too often. anything you do to lift your truck speeds up the process of wear and tear of certain parts. i wouldnt be too worried about it though.

Crawl under there and you'll see why. The front diff is attached to the top of a crossmember. The only way to drop it is to get rid of/modify the crossmember. To complicate things the folks at Toyota bolted the steering rack to the back of it. For the cost of the procedure you could engineer and manufacture a 4,5, or 6 inch lift for about the same money. That's why you can get a 3" lift for a reasonable amount, but there's a big jump in price (gap) for anything above that.

If the boots were kept really clean that would help them last longer right? I had it up on a lift so the suspension was at full droop and the fins were rubbing so I thought if you could lube that somewhat it might be helpful, I tried silicone on it but it didnt seem to stick much. WHat about usuing petroleum jelly or is that bad like grease and oil are on rubber too since its a petroluem product?

I would expect that lubing the OUTSIDE of the boots would attract dust, dirt, and small rocks, thus creating more of a problem with wear and tear.

Good call. Do they make High angle boots for this application? I ve heard about people looking for them but dont know if they have any.

I run 3.5" up front, for around 25k now, without boot failure. Mind you I am getting close to replacing them as preventive maintance thing. I believe the biggest factor for increased wear is not cleaning them. If you leave dirt between the fins, it acts like sand paper, increasing boot wear. I regularly hose mine off at the end of the day- it's worked so far.

I wold think that the petroleum jelly would damage the rubber. It would give dirt something to stick to. I had a 4runner with craked up T-bars and used spray silicone. The silicone not only lubes, but doesn't allow dirt to stick.

One of my boots has a slight rub and so about once a week or so I just go under and give the fin that rubs it a good wipe with some armoral. Keeps it clean and makes it a little slick as well.

Yeah,, theyre are high aggle cv boots out there. It's been a while since I've seen where you can get them though. If you do a search on the old board, i am sure you can come up with a couple of places.

There is a link on WWW.WATTORA.COM for spiral CV boots that are supposed to work with high angles better but the website is down right now so I couldn't retrieve the link.

One of my friends has a fabtech lift 3.5", and blew out a CV boot. The toyota dealer said to use Porsche CV boots.

A lot of the problems people have had depends on the year as slight Toyota tweaks have made problems lifting LESS of a problem. I met a guy with a 97 and with a 3" spacer his CV's clicked while driving everywhere.
I have an 01 and have a combo 3" spacer and 1.75" lift spring and it gives me 4" of lift for 26k and have NEVER once cleaned my CV's or anything, whenever I happen to be under truck I GLANCE at them and there is ZERO wear on them worth even giving a thought to. ( I know I have 4 inches to you nay-sayers as my 3" all pro springs required a 1.5" lift shackle to level out my truck).
I would say you should be GOLDEN if you are 2000 or newer ( I've had a 2000 so I can speak to that, older may be ok too, but I'm not gonna assume ) with a 3" cornfed or similar top out spacer. Sounds like your a bit concerned so get a diff drop for a bit of an angle ease.

Downey makes high angle boots that should help. I've been running 3" lift with ADD for 3-4 years with only 2 torn boots and the first was from a stick, not rubbing. Just get the Downeys and put them on when the stockers detonate.
