TiC Shift Linkage Bushings for 2004-05 Subaru STI
Turnin Concepts address's the dreaded second to third miss shift that is due to slop in the 2004 and 2005 Subaru STI stick. TiC's replacement shift linkage bushings for the USDM Subaru Impreza STI will help eliminate the free play of the shifter leading to an overall better feel of the stick, and making the gear selection "click" into place.
Between the shifter linkage arm and the control arm going into the transmission is a joint. It is this joint that is causing the lateral play in the stick. The stock joint is made of a u-joint assembly consisting of two tubes welded at right angles. In these tubes are the bushings. Inserted into these bushings are sleeve bearings, and running through the sleeve bearings are the bolts that hold the whole u-joint between the linkage arm fork and the control arm fork. In the stock configuration there are two places in this joint that create play in the system. The first is the clearance gap between the bolt and the sleeve bearing. The second is the gap between the sleeve bearing and the bushings. It is that second point that our bushings address. Over time the soft rubber bushings compress which translates to a greater amount of slop at the end of the stick.
TiC's polyurethane bushings are designed with tighter tolerances than the stock bushings. The tighter tolerances ensure significantly less slop over stock, while the polyurethane compound we use is much more resistant to compression, but at the same time compliant enough to keep NVH at an acceptable level.
