What size is the shift knob on a RSX?
The typical shift knob for a Honda/Acura RSX uses a 12x1.25 mm metric thread, with the knob itself commonly around 52 mm in diameter. This holds for most 2002–2006 Acura RSX models, including the Type-S, but exact measurements can vary by year and trim. When upgrading, verify both the thread size and the desired knob diameter for your vehicle.
Shift knob size can refer to two separate measurements: how the knob threads onto the shifter (thread size) and how large the knob feels in your hand (diameter). The following details help buyers and owners confirm compatibility and comfort when replacing an RSX shift knob.
Thread size and mounting
Before replacing a shift knob, confirm the hardware that attaches it to the shifter to ensure a proper fit.
- OEM RSX shift knobs typically use a metric 12x1.25 thread for manual transmissions.
- Many aftermarket knobs include adapters to fit alternative pitches; check compatibility with your exact RSX year and trim.
- If installation is difficult or the knob doesn’t thread on smoothly, inspect the threads on both the knob and the shifter for damage or debris.
Concluding note: Always verify thread pitch before purchasing a replacement knob, and consider keeping the original knob for reference when shopping for aftermarket options.
Knob diameter and feel
Knob diameter influences grip and shifting comfort. OEM RSX knobs are typically around 52 mm in diameter, while aftermarket options can range from about 45 mm to 60 mm depending on style.
- Typical OEM diameter: ~52 mm (about 2.0 inches).
- Smaller aftermarket knobs: roughly 45–48 mm for a more direct, sportier feel.
- Larger aftermarket knobs: up to 60 mm or more for a chunkier grip; ensure clearance with the boot and parking brake area.
Concluding note: When selecting a knob, balance thread compatibility with your preferred grip size and shifting feel; many drivers find a 50–54 mm range to be a comfortable baseline for daily driving.
Year and trim notes
While the guidance above covers most RSX models, there can be exceptions by year, trim, or factory options. The Type-S and base RSX share the same manual transmission in this era, but verify your specific vehicle’s details if possible.
Bottom line: For a typical RSX, plan for a 12x1.25 mm thread and a knob diameter around 52 mm as the baseline. If in doubt, measure the current knob’s diameter and confirm the threaded stud on the shifter before purchasing any replacement.
Summary
In short, the standard RSX shift knob uses a 12x1.25 mm thread and about a 52 mm diameter. Always confirm both thread pitch and knob diameter for your exact model year and preferred feel when upgrading, and test-fit if possible.
