Hello,

Smoother shifting

I have essentially every drivetrain piece you can get to solidify everything and improve my shifter feel. This was the final piece of the puzzle. Looks good too.

Hello,

Thank you for your review. Glad to hear you are enjoying a smoother shifting experience!

Regards,

Awesome upgrade

Finally get to install it. Help beefed up the rear and shifting improved.

Hello,

Thanks for the feedback! Awesome to hear installation went smoothly and the added support improved shifting.

Regards,

Cusco goodness!

Added this to my 2010 Legacy GT. Fits perfectly and beefed up the rear end a bit. Thanks Subimods!

Hello,

Thanks for the feedback! Happy to hear it fit your Legacy GT perfectly and added the reinforcement you wanted.

Regards,

Beautiful, bulletproof, less play in the rear = no brainer

As I continue on my mission to address all the play in the drivetrain, the Cusco rear diff carrier was an obvious choice. Stiffer bushings, beefier part, good price. On top of it, who doesn't love that Cusco blue!

Installation was straightforward, though make sure you get replacement nuts as bolts, as the OEM hardware is only meant to be torqued down once.

Hello Lucas,

Thank you for your review! The Cusco rear diff carrier is a strong choice to eliminate drivetrain play, and yes, that Cusco blue is always a bonus.

Regards,
