Helical Front LSD

Factory helical front LSD provides smooth, progressive, noise and maintenance free operation. The 5-speed helical unit was fitted to Ver.5/6 STI Type RA and S201. 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.

Usually ships in 3 to 4 days.
