Factory helical front LSD provides smooth, progressive, noise and maintenance free operation. The 6-speed unit has been the standard factory front LSD on all MY06 and newer STI models. The helical LSD is superior in performance to the Suretrac unit fitted to earlier STI's and is a great upgrade for the open diff in the SpecB.
Note that the 5-speed helical LSD as originally fitted to the Ver.6 STI Type RA model has now been discontinued by Subaru. In its place we are supplying a 6-speed helical LSD that has been modified to fit the 5-speed casing.
Usually ships in 3 to 4 days.
