Wavetrac LSD for Ford Falcon, Mustang, Focus & 9-Inch
Wavetrac helical limited slip differentials for Ford cover the BA/BF/FG Falcon XR6 Turbo and XR8 M86 rear axle, the S550 Mustang and 2005-2014 Mustang 8.8-inch, SVT Cobra IRS, F-150 Raptor front, Focus RS and ST, Fiesta ST, and the Ford 9-inch in 31, 33 and 35-spline - including High Friction versions for drag and high-traction use.
Choosing the right Wavetrac
For the 9-inch, choose by axle spline count (31, 33 or 35) and whether you want the standard or High Friction unit. The S550 Mustang unit suits 3.31, 3.55 and 3.73 final drives. Front-wheel-drive Focus and Fiesta units are matched to the gearbox (M66, MMT6, IB6).
Installation & gear oil
Each Wavetrac is supplied as a complete differential carrier ready to accept your factory ring gear. Transferring the ring gear and setting backlash and bearing preload should be done by a professional driveline specialist. No break-in is required. Use the manufacturer-specified gear oil, avoid limited slip friction modifiers, and never use Red Line ShockProof or similar oils - they void the Wavetrac warranty.
