Hi 2006 Outback 25i owner,

2″ of lift is not too realistic for that car.  We find frequent front CV axle failures for cars lifted 1.5″ or more.  The CV angles become too great and the CV’s are already old.
WHEN you do replace the front CV axles, only get the factory REMANUFACTURED ones from SUBARU (can order from us for a few dollars less typically).  $99 CV axles from Auto Zone tend to fail quickly. (FYI)
I HIGHLY RECOMMEND for a good solid lift on ’05-09 Outbacks:
Our King RAISING SPRING kit for $499 (less $30 automatically if ordered online and shipped in the USA)
and also get our KYB struts featuring a thicker shaft, up-rated rear strut: $318 for the set of 4 (F+R)
I would also get our Heavy Duty Front strut tops (listed under fully assembled parts CATEGORY for $145/pair
You can RE-USE all the other bits (dust boots, bump stops, perches, rear tops, etc).
But to get ALL NEW parts, including those HD front tops and make INSTALL a pretty easy affair for you and a buddy on a weekend, get the STRUTS, the SPRING KIT and the options for FULLY ASSEMBLED FRONTs and FULLY ASSEMBLED REARs (found under FULLY ASSEMBLED PARTS category.
You then get “fully loaded” strut and raised spring assemblies ready to bolt in each corner.  No spring compressors or figuring out how to stack parts.  This ~1.2″ of lift is plenty to fit bigger tires and give you more clearance while keeping the car reliable. HANDLES GREAT on the road, much better than a spacer-only lift for sure.
Most customers report it handles better than when  the car was new, and this is due to that heavy duty King Spring combined with the up-rated rear strut.  Eliminates “ghost walking” and it limits how much the rear goes up and down and therefore keeps from toeing-out in a bump in a corner…
