leetdrv Posted May 25, 2021 Share Posted May 25, 2021 The part numbers are different 20370AG00A (GT), 20370AG000 (Spec B) Is there also a difference comparing them side by side? Link to comment Share on other sites More sharing options...
Max Capacity Posted May 25, 2021 Share Posted May 25, 2021 Yes, the Spec B's have different struts than a GT. I do believe there is not a left or right side Hat as they are called. https://www.google.com/search?q=spec+b+bilstein+shocks&rlz=1C1OKWM_enUS906US906&oq=Spec+B+Bi&aqs=chrome.0.0j69i57j0i22i30l3.8835j0j15&sourceid=chrome&ie=UTF-8 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

leetdrv Posted May 26, 2021 Author Share Posted May 26, 2021 I'm getting a spec b suspension together and ordering parts. I'm aware that the shocks and the front top hats are different than the typical Legacy GT. There question is, are the rear top hats different? Thanks!

Max Capacity Posted May 27, 2021 Share Posted May 27, 2021 I just went to my local dealers website, the rear top hats are the same part number for my 05 GT wagon and for my 09 Spec B. Your local dealer should have the same parts list. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Max Capacity Posted May 27, 2021 Share Posted May 27, 2021 I'll bet you could call Bilstein and ask them too. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

leetdrv Posted May 28, 2021 Author Share Posted May 28, 2021 SOA parts catalog and local dealers have the same part numbers for GT and SpecB front top hats also. We know they are different. Other online sellers of Subaru parts list different part numbers as stated above. I'm just gonna order 20370AG000 and be done. I'll report when I take everything apart. Max, thanks for looking into it! Link to comment Share on other sites More sharing options...

Max Capacity Posted May 28, 2021 Share Posted May 28, 2021 I know your in NV but if you call the dealership and tell them you have a Spec B they should be able to tell you the correct number. I have a great relationship with the Parts guys at my local dealership. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Max Capacity Posted May 28, 2021 Share Posted May 28, 2021 On the Spec B page I see both struts are listed, if you click on them, the $136 one shows its for a normal GT click on the $464 (yellow) one and it says Spec B. You need the $100 front mount upper for a Spec B. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
