REBUILT BOXSTER G87/20 G87/21 GEARBOXES

Boxster enthusiasts can now have a rebuilt gearbox without having to go to the factory! GBox is rebuilding the Boxster G87.20/G87.21 transaxles with new OEM parts.

Completely disassembled, fully inspected and cleaned; all worn/damaged parts replaced (new OEM parts are available); gear stack blueprinted; ring and pinion 'R' and backlash set to spec. See our rebuild procedure.

Limited-slip differentials available: torque-biasing and plate-type.

Cryo_REM processing is available to lower friction and increase longevity. See our Cryo-REM page.

GBox can eb-weld new dog-rings onto your gears; no need to buy a new (expensive) gear.
