a 305 is more like a 34.5 than a 33 it would prolly sit at 33 when aird down comfortably i may be wrong but a 305 is closer to 35 than 33

 

A 305 70 would be a 34. A 305 65 would be a little under a 33.

 

The Teraflex BB comes with new shocks and new pucks for the lift, but there are shock adapters which allow you to run the stock shocks. You could go with the coil lift, which replaces just the stock coils and allows you to run the stock shocks. Or a third option which is the coil lift with shocks, which would become the Teraflex 2.5" Lift kit.

So...
1). Teraflex 2.5" BB = new shocks, new pucks(for height), stock coils, or if you want, shock adapters to allow you to run stock shocks
2). Teraflex Coil Lift = new coils, stock shocks = $410
3). Teraflex 2.5" Lift Kit = new shocks, new coils = $610

I know what you mean, my budget is cutting my dreams short too, so I have to work and save up. If you don't want to get the Teraflex, than the Daystar would be fine. You should check out www.screaminlizard.com , because they have some inexpensive suspension lifts AND lol they are conveniently located in Texas. You could possibly run the Full Traction 2" Economy Suspension Lift for only $140 that allow you run the stock shocks and coils. Similar to Daystar, only problem is, the FT lift comes with problems, so not really recommended, but it can work.

 

305/65R17 = 32.8" tall, 12.2" wide

305/70R16 = 33.1" tall, 12.2" wide

Most people would call those "33x12.50's"

 

Im understanding it better but to be sure here is what Im looking at.



Part Number: TER1355200
2007-09 JK Wrangler and Unlimited;Shocks Not Included;Max Tire Size: 35x12.50

Lift raises vehicle 2.5. The Budget Boost will fit on the 2007 2 door JK Wrangler, and 4 door JK Unlimited vehicles. The Budget Boost is designed to fit 35 tires.


I was told by the salesperson I needed new shocks to use with this?



This is what I have on order:



Daystar Lift Kits provide both front and rear lift in the 2" to 3" range. Front lift is generally the same as with our leveling kits, while rear lift comes in the form of rear coil spring spacers, longer shackles, add-a-leafs, or a block and U-bolt kit. Which method used is spelled out in the application description. Daystar's Lift Kits are the perfect solution for gaining ground clearance and the room to step up a few tire sizes...Do your homework and you'll see that we've done ours!

Here's the wheels you like, with the Dick Cepek FC-II 33x10.5" tires. I think this is somewhat aggressive for a relatively small, narrow tire. There is a 2.5" RC lift, which is a pretty cheap mod:

On the Daystar Lift Kit, I'm pretty sure that the maximum tire size is not 31". The maximum tire size would be 33" and 35" would be pushing it.

On the Teraflex lift kit, it is recommended that you get new shocks with it, but you can purchase shock adapters that come with the kit to allow you to run the stock shocks. I would recommend getting new shocks, but it all depends on what you are willing to pay.

If you do not want to get the adapters, than you could look into the FT or go with the Daystar like you originally planned.

Just to give you a perspective, I'm going with the Teraflex 2.5" BB and going with 285/70R17 BFGoodrich A/T on 17x8 Pro Comp 7005s.

 

I'm still struggling to understand. I now got the concept of back spacing. I did the tire/wheel website that compares my current setup with other setups (i choose procomp)... however, it would only sell me 18 in rims. And tire size on the 18 was limited (265/60?)

what is a rule of thumb for max tire size. I carry a 12 yr old girl in the back... wouldn't want a tire coming off at highway speed.

Well for tire size I have been convinced to go smaller than 18" I have a setup with other stuff but it came down to for $160. more I can have 5 - 17" duratracs with 5 new pro comm wheels! Compared to just having 5 new 18" MTR tires.

Also when you go with new wheels you wont need wheel spacers which cut the price some. I heard one too many horror stories about wheels falling off. Wheel spacers require alot of maintance you need to keep checking on them.

Im sure many have wheel spacers without issues but I just like one less thing to worry about. As for as pricing it just makes sense to go to 17" or 16" opens up alot more options and get alot more bang for the buck.
