4.5” Subaru Lift kit. Maximize clearance and off road capability on your 2003-2008 Subaru Forester. This kit consists of a 2.5” strut spacer, 2” Strut spacers and 2” full Subframe spacers kit correct for CV joints angles. Better CV joint Geometry will increase life span. Spacer Kit  includes spacers for Engine Crossmember, Transmission, Carrier bearing, Differential hanger and rear Differential. Install time 10-12 hours min. 

*LEAD TIME: NO LEAD TIME. DONT ASK. These kits are built in batches.


For extreme strength and reliability, we Laser cut and form 1/4" Steel with added gussets. All holes are Laser cut for accurate fitment. 2.5” Lower lift bracket, ¼” Steel laser cut for precision. Lower lift brackets are manufactured for a high tire clearance. These allow 2.5 inches more of spring perch for a larger tire. This will give you a finished lift product of 2.5 inches.  

Factory Alignment

To maintain good cv joint angles when exceeding 2.5" of lift subframe spacers will be needed to keep the cv joints within their limitations. Goal is to keep cv joints within 2-2.5" over factory angle.To maintain factory alignment specifications Camber and improved Caster offsets are built into the steel spacers. - We recommend that you get an alignment after your install, as there may still be a human error factor when installing the camber bolts.   

Trailing Arm Spacers

3” Trailing arm spacers are included in this kit. 

Rear height additions

We also offer a few different heights of Rear spacers to compensate for added load in the vehicle or level vehicles out, if they currently aren’t sitting level.  Added height is built in one solid spacer, no stacking of different spacers. Adding 3/8” compensates for mild loads, ½” for extreme loads. If you are hauling excessive loads we would recommend standard height king springs.
