Common Issues with Stock Shifters:

• Long, vague shift throws
• Excessive play in the shifter
• Inconsistent gear engagement
• Reduced driver confidence

If you have a K-Swap car, applications definitely go a bit further because this shifter will also be used on several different K-Swap setups.

Product Overview: Billet Shifter Box Assembly

This billet unit is engineered for K-series equipped platforms and K-swap applications, offering a major upgrade in both performance and durability.

Key Features:

• CNC-machined billet aluminum construction
• Designed for K20 and K24 engines
• Short-throw shifting for faster gear changes
• Reinforced design to eliminate flex
• High-performance, track-ready build
• Improves shift precision and feel

Compatible Vehicles

Honda Models:

• Accord (2003–2007)

Acura Models:

• TSX (2004–2008)
• TL
• CL7 / CL9 chassis

Engine Compatibility:

• K20 engines
• K24 engines

(Also suitable for K-swap applications—verify linkage or cable compatibility.)

Below we have tried to breakdown these kind of applications in the most simple way imaginable:

OEM 2004-2008 TSX cables, cable bracket, and transmission.
OEM 2003-2007 Accord cables, cable bracket, and transmission.
OEM 2006-2011 Civic Si (K20Z3) cables, cable bracket, and transmission.
As noted above, you’ll be able to see we have a listing for the K20Z3 transmission. We accomplished this by designing the shifter with two different cable mounting positions.

The rear cable position is used only for the K20Z3, whilst the front cable position is used for both the TSX and Accord shift setups.

Why This Shifter Stands Out

Compared to OEM and basic aftermarket options, this billet assembly offers:

• More precise and direct shifting
• Reduced throw distance for quicker shifts
• Increased durability under high stress
• Improved driver feedback and control

Solved the weak side arm problem by the use of a delrin pivot ball and included some adjustment to shorten the shift throw up to 35%
Get rid of any flex or movement that is found in the OEM TSX/Accord plastic box

Ideal For:

• K20 / K24 performance builds
• Track and racing applications
• Daily drivers seeking better shift feel
• K-swap conversions

The TSX/Accord Shifter is made almost entirely of 6061 billet aluminum, with some stainless steel in the mix for additional strength

Installation Notes

• Direct replacement or upgrade for compatible vehicles
• Ensure compatibility with cables/linkage
• May require minor adjustments depending on setup
• Professional installation recommended

This shifter is an immediate drop in replacement for all three cars and their matching OEM cables, cable brackets and transmissions
