TrakMotive SB-8107XTT CV Axle Shaft - Front, Front Left or Front Right

Extended Travel CV Axle for Subaru WRX and STI

TrakMotive SB-8107XTT is an extended travel CV axle shaft built for Subaru performance applications that need more suspension movement than a standard OE axle can provide. It adds up to 44 mm more travel than an OEM CV shaft and allows CV joint articulation up to 47 degrees for extreme suspension angles.

The TrakMotive Extended Travel CV Axle Shaft line is focused on driveline movement for lowered, lifted, or heavily articulated setups. This SB-8107XTT axle is a new replacement part with a neoprene boot, included axle nut, and OE-style spline and joint configuration for the listed Subaru WRX, WRX STI, and Impreza front applications.

• Up to 44 mm more travel than a standard OEM CV shaft
• CV joint articulation up to 47 degrees
• New axle shaft with neoprene boot material
• Included axle nut with M22 x 1.5 thread, 31.8 mm hex size, and stake locking type
• Male inboard joint with 25 inboard splines
• Conventional outboard joint with 27 outboard splines
• Overall compressed length: 31.54 in. (801 mm)
• TrakMotive part number SB-8107XTT

Detailed Product Overview

SB-8107XTT is engineered for front driveline service on Subaru WRX, Subaru WRX STI, and Subaru Impreza models where suspension geometry places greater demand on the CV axle. The extended travel design helps maintain axle engagement through larger suspension cycles, while the higher articulation range supports vehicles with extreme articulation requirements. This makes it a direct-fit option for front left, front right, and front positions listed in the fitment data. This part cross-references TrakMotive SB-8107XTT for the same application.

Compatible With 2020-2021 Subaru WRX, front; 2015-2019 Subaru WRX, front right; 2015-2019 Subaru WRX, front left; 2013-2019 Subaru WRX STI, front right; 2013-2019 Subaru WRX STI, front left; 2008-2014 Subaru Impreza, front right; and 2008-2014 Subaru Impreza, front left. The part number SB-8107XTT is a useful reference when matching the correct front axle shaft for these Subaru applications.

What This CV Axle Helps Address

• Front axle binding caused by increased suspension travel
• CV joint angle limitations on lowered or lifted Subaru setups
• Axle shaft movement issues during aggressive suspension articulation
• Wear from repeated high-angle CV operation
• Front driveline replacement needs on WRX, WRX STI, and Impreza models

Installation Notes and Tips

Verify front position, spline count, and axle nut specifications before installation. The included axle nut uses a 31.8 mm hex size and M22 x 1.5 thread. Always inspect related suspension and driveline components for wear, and replace in pairs where the vehicle service procedure calls for matched axle service. Confirm fitment against the vehicle’s year, model, and front position before ordering SB-8107XTT.

Quality Assurance

TrakMotive designs the Extended Travel CV Axle Shaft line for demanding suspension geometry and driveline movement, using a sliding center bar and high-angle CV joint design to meet the needs of extreme articulation applications.
