Sequential Shifter: Magnum

Here is the polished, high-performance rewrite for your Tremec Magnum product page. I kept the layout consistent with your previous direct-mount shifters, placing the crucial gearbox identification details and the Left/Right lever warnings front and centre to help prevent ordering mistakes.

Tremec Magnum / Magnum F / Magnum XL Sequential Shifter

Convert your standard Tremec Magnum H-pattern gearbox to a true sequential operation. Designed for straightforward installation, this bolt-on kit delivers repeatable, lightning-fast shifts under heavy racing loads.

⚠️ Which Version Do You Need? (Please Read)

We manufacture variants for three specific Magnum gearboxes. Please select the correct version from the drop-down menu based on your transmission:

• Tremec Magnum (Original): Features the large 6-bolt shifter mounting flange.

• Magnum F: Designed for the 4th Gen Camaro / Commodore upgrade.

• Magnum XL (Ford Upgrade): Features the extended housing and a 4-bolt shifter mount. Note: The Magnum XL requires a small physical modification to the gearbox for fitment.

If you are unsure which version you have, please contact us before ordering and we will help you identify it!

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.

Crucial Ordering Guide: Right vs. Left Lever

Please read carefully before selecting. Do not choose a Left Lever simply because your car is Left-Hand Drive. The correct choice depends entirely on your specific transmission tunnel clearance.

• Right Lever (Standard Choice): Offset 12mm (1/2 inch) to the right. This positions the shifter as centrally as possible. Almost all Japanese, Australian, and general custom builds require the Right Lever.

• Left Lever (Specialty Choice): Offset 48mm (2 inches) to the left. This is a severe offset typically only required for 4th Gen Camaros, Dodge Vipers, and a few specific older chassis.

Fitment & Installation Notes

All of our direct-mount shifters are designed to fit the gearbox, not a specific car chassis. 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!
