Torque Solution TS-SU-705 Shifter Linkage Pivot Bushings Combo 06-21 Subaru STI

Vehicle Fitment

• 2006-2021 Subaru Impreza WRX STI (All Trims - Base, Limited, Special Edition; 6-Speed Manual)

Fitment Notes

• Fits all body styles of the 2006-2021 WRX STI: Sedan and Hatchback (where applicable by model year)
• For manual transmission (6-speed STI) equipped vehicles only
• Does NOT fit the Subaru WRX (non-STI) - the WRX uses a different shifter linkage configuration
• Does NOT fit the 2004-2005 STI - see Torque Solution TS-SU-704 for that application
• This is a combo kit - replaces both the shifter linkage bushings and the shifter pivot bushing in a single purchase

Features

• Replaces the OEM rubber shifter linkage bushings with precision Delrin bushings to eliminate shifter play and vague engagement feel
• Replaces the OEM rubber pivot bushing with a Delrin alternative for a more direct, mechanical shift feel throughout the gate
• Self-lubricating Delrin material maintains smooth operation over time without requiring periodic re-greasing
• Significantly reduces excessive shifter end play - delivers a more notchy, precise throw so each gear is exactly where it should be
• Engineered and torture tested for both street and track use under sustained high-load and high-frequency shifting conditions
• Improved 60-foot times and consistency for drag and road course applications due to reduced missed-shift potential
• Delrin is specifically selected by Torque Solution engineers over aluminum and brass for its combination of hardness, self-lubrication, and vibration compliance
• Backed by Torque Solution's Limited Lifetime Warranty

Product Description

The Torque Solution TS-SU-705 is a complete Shifter Linkage and Pivot Bushing Combo Kit engineered specifically for the 2006-2021 Subaru WRX STI. The factory rubber bushings used at the shifter linkage and pivot point are a well-documented weak point on the STI's 6-speed manual transmission - over time (and accelerated by track use or aggressive shifting), they compress, deform, and introduce slop into the shifter that manifests as vague gate engagement, excessive throw, and an overall imprecise feel. The TS-SU-705 addresses this directly by replacing both the linkage bushings and the pivot bushing with precision-machined Delrin, eliminating the rubber compliance entirely and restoring a direct, mechanical connection between the shifter and the transmission.

Torque Solution specifically chose Delrin (acetal resin) over aluminum, brass, and generic plastics used by competing products. Unlike aluminum or brass, Delrin is self-lubricating - it doesn't require grease packing or periodic maintenance to maintain smooth operation. Unlike cheap plastics, Delrin retains dimensional stability and wear resistance under sustained heat and mechanical stress from high-frequency shifting. The result is a bushing that is stiff enough to eliminate feel-degrading play while remaining compliant enough to avoid transmitting excessive vibration into the cabin. The combo kit format means both wear points are addressed in a single purchase and a single installation - a more efficient solution than sourcing linkage and pivot bushings separately.

This kit has been street and track torture tested by Torque Solution, and is suitable for daily drivers, weekend track cars, and dedicated race STIs alike. Reduced shifter end play directly translates to more consistent lap times, improved 60-foot times, and fewer missed gears during aggressive shifting sequences. Backed by Torque Solution's Limited Lifetime Warranty, the TS-SU-705 is one of the most cost-effective and highest-impact drivetrain improvements available for the 2006-2021 Subaru WRX STI. Note: This kit does not fit the 2004-2005 STI - see TS-SU-704 for that application.
