Description
Toyota R154 & Aisin AR5 Sequential Shifter Conversion Kit
Convert your standard Toyota R154 or Aisin AR5 H-pattern gearbox to a true sequential operation. Designed for straightforward installation by anyone with basic mechanical skills, this bolt-on kit delivers repeatable, lightning-fast shifts under heavy racing loads.
⚠️ Which Version Do You Need? (Please Read)
Because these gearboxes have several variations, please review the product gallery images carefully and note the following before ordering:
-
R154 Styles: We now manufacture variants for both the early “Supra” style and the later “Tripod” style R154 gearboxes. Ensure you select the correct version for your specific transmission.
-
Aisin AR5: We have recently added AR5 compatibility, but please note this kit is specifically designed for the Pontiac Solstice and Saturn Sky versions of the AR5 only.
-
Mounting Position: In all configurations, this sequential shifter mounts directly to the gearbox housing. It does not sit back on an extended factory bracket. Please verify this forward mounting position suits your custom chassis needs before ordering.
Performance Benefits: Get the right gear, every time.
The push/pull sequential motion drastically improves driver coordination under high-G loads compared to a standard H-pattern. It makes it physically impossible to grab the wrong gear—eliminating accidental 2-5 upshifts that cost you races, or 5-2 downshifts that destroy engines.
-
Bulletproof Durability: Specifically engineered to handle the harsh loads of hard driving with synchro gearboxes. You will not break this shifter.
-
Fast & Consistent: Simple pull-back to upshift, push-forward to downshift.
-
Precise Mechanical Feedback: Know exactly when the gear engages.
-
Mechanical Reverse Lockout: Added safety and ease of use.
-
True Neutral: Neutral can be selected between every gear.
What’s Included in the Basic Kit?
The core kit includes the main shifter unit, shift knob, and everything required to physically convert your gearbox to sequential operation.
Available Shifter Options & Upgrades
Customise your setup to fit your exact interior and data-logging needs:
-
Gear Position Sensor: Outputs a 0-5V analogue signal. Essential for aftermarket ECUs or digital dashes, and can be used for gear-based boost control.
-
Digital Gear Indicator: A sleek dash display showing your current gear (Note: The required position sensor is now included in the price of this indicator; no need to buy both).
-
Shifter Surround: Neatly seals the shifter and the transmission tunnel opening to keep track noise and exhaust fumes out of the cabin.
-
Offset Lever: Moves the shift lever forward or backward. A must-have for Vipers and Holden Commodores.
-
Direct High Lever: Mounts directly to the shifter, providing a tall shift position while using internal linkages to preserve the short throw.
-
High Linkage Lever: Moves the lever further forward or backward while providing a high mount and maintaining a short throw. Ideal for custom race car driving positions.
Fitment & Installation Notes
All of our direct-mount shifters are designed to fit the gearbox, not a specific car chassis. Because this shifter mounts directly to the R154/AR5 housing, you will likely need to trim your transmission tunnel to clear the new mechanism. We highly recommend adding the Shifter Surround option to seal this modification cleanly.
In most custom-swapped vehicles, the shifter will clear the interior trims and look factory-clean once installed. If you are unsure what a finished installation looks like in your chassis, send us a message!
