When original parts for popular vehicle models were discontinued by the manufacturer, transmission component specialist Speed Tek Auto Racing faced a significant challenge.
This kit includes the following:
- 1 x 3rd and 4th gear shift sleeve
- 1 x inner hub
- 2 x heavy-duty inner shift insert springs
- 3 x heavy-duty shift inserts
Designed for 71C transmissions equipped with a close-ratio gearset featuring integrated synchronizers.
This kit is an essential component for reinforcing Nissan Skyline (R32) and Silvia series 5-speed transmissions. OEM inserts often wear out over time, leading to missed shifts as the synchronizer rings fail to engage properly. Since OEM sleeves typically wear out after 20 years or more, this kit is crafted from superior modern materials to enhance both durability and performance.
