Synchrotech 1st-6th Carbon Synchro Set Master Rebuild Kit RSX Type S 05-06 Civic Si 06-11 MK-SYN117

Unlike the carbon/moly or carbon fiber weave synchros that have a spray coating or a woven carbon fiber fabric, Synchrotech Pro Series Carbon Synchros have a full carbon composite lining. Utilizing carbon-carbon technology initially developed for the Aerospace industry, our carbon composite material acts as a braking material during gear engagement. This allows for quicker and more precise shifting and prolongs the life of the synchro sleeve and gear engagement teeth.
Included: Synchrotech® 1-6 Pro Series Carbon Synchro Set , 1-6 springs, 1/2/3/4/5/6 sleeves, 4 shaft bearings, bearing clip, 2 axle seals, input seal, and shift rod seal.

Now also includes 5th-6th sleeve!

Fitting: 2005-2006 Acura RSX Type S K20 6 speed (NSN4), 2006-2011 Civic Si (PNN3 PNN4 SPNM)
