IAG PERFORMANCE 1ST-6TH CARBON SYNCHRO SET FOR 2004 - EARLY 2006 STI




IAG Carbon Synchro Set for 2004 - Early 2006 STI 6 Speed

SHIFTS BETTER, LASTS LONGER

IAG’s Carbon Synchro Set is an essential upgrade if you are rebuilding your transmission or looking to get a little more performance out of your 2004-2006 Subaru STI. Worn out synchros, gear grinding and even transmission housing damage can occur from aggressive driving, forceful shifting, overuse, or even normal wear and tear. Our Carbon Synchro Set offers smoother shifting and improved reliability, it is a vital enhancement for your Subaru’s transmission.

DESIGNED FOR DURABILITY

IAG’s STI 6 Speed Synchro Gear Set features dual carbon friction surfaces. This not only extends the life of the synchro sleeve and gear teeth but also allows for faster and more precise shifting. The IAG Synchros are made from Japanese brass, which is known for durability and its ability to be intricately machined. Our Carbon Faced Brass Synchro Set is precision machined, providing an enhanced shift feel and less wear between moving parts.

INCREASED SURFACE CONTACT

Each IAG Synchro Set was designed to maximize surface contact between the gears and synchros. This decreases gear shift times in your Subaru STI 6 speed transmission by increasing the grip for quicker engagement. Increased surface contact also enhances the driving experience by demanding less effort to engage the gear.

ALL SYNCHROS INCLUDED IN SET

Unlike the available OEM Synchros, this Synchro Set includes the first, second, third, fourth, fifth and sixth gear carbon synchros. There’s no need to search for missing synchros or hunt down rare OEM parts. Everything you need comes in the IAG Six Speed Carbon Synchro Set.
