Ford 9-Inch HD Pro Aluminum Third Member Assembly (35-Spline)

Complete, ready-to-run, drop-in HD Pro Aluminum 9-inch third member set up for 35-spline axles. Don't let its good looks fool you, this unit is designed for serious abuse in street/strip, pro-touring, and autocross applications. Additionally, the aluminum construction reduces weight by 15 pounds compared to a standard nodular iron case

PROP 65 WARNING:

Complete HD Pro hi-performance, lightweight drop-in 9-inch third member set up for 35-spline axles. Includes a broad selection of differential types and gear ratios, so it’s easy to build the perfect solution for your street rod, muscle car or truck

All Currie 9-inch third members are assembled by our in-house experts with decades of rearend setup and assembly experience, so you can trust the finished product

 

Currie 9-inch Third Member Features:

  Gear Case - HD Pro aluminum 9-inch gearcase features billet bearing caps with a through-bolt design for improved rigidity and billet aluminum pinion support with 7/16" ARP fasteners and oil channels designed to maximize oil flow for extended driving
     
  Load Bolt - This optional feature prevents the ring gear from deflecting under high torque loads for improved reliability during hard launches and severe use
     
9-inch master Bearing Kit   Master Bearing kit - Includes Timken master bearing kit with seals and solid pinion spacer
     
  ARP Fasteners - Includes upgraded ARP ring gear bolts for enhanced strength and durability 
     
Assembly labor   Labor - Fully assembled and set up in-house by skilled professionals

 

 

9-inch Third Member Options:

9-inch Ring and Pinion   Gear Ratios - Select from a wide range of ratios. Currie uses only the highest quality Motive Gear Performance® series (Orange box) ring and pinion sets
     
9-inch Limited Slip   Differential Options - Choice of 35-spline helical gear limited slip, automatic locking differential or a steel spool
     
  Pinion Yoke - Choice of 1350 short yokes in nodular iron, forged steel or billet steel
     
Gear Polishing   REM® Isotropic Polishing - Removes surface imperfections created during the gear manufacturing process. Polishing eliminates the need for a break-in period, decreases friction, reduces operating temps and removes stress risers, to help gears last longer and run quieter

 

 

Differential Options Explained

Truetrac and Wavetrac - Helical gear limited slip differentials (LSD) are the modern replacement for the classic clutch style limited slip differential. Under normal driving conditions, HGLSDs operate as a standard or open differential, allowing one wheel to spin faster or slower as necessary without the noise or harsh operation of a clutch style limited slip. When a drive wheel begins to slip, the helical gears inside the differential automatically engage, transferring torque to both rear wheels to maximize traction. When the wheels regain traction, the differential resumes normal operation. Unlike traditional clutch type limited slip differentials, HGLSDs require no special oil additive or maintenance to replace worn and tired clutches, as these units have no wearable parts, require no special maintenance and maintain their torque bias for the life of the unit.

Detroit Locker - Automatic locking differential, designed to lock and unlock automatically when torque is applied in either forward or reverse directions when locked it acts like a spool driving both wheels equally. When coasting or rolling into a corner (no torque applied) the Detroit Locker unlocks and momentarily operates like an open differential permitting the wheels to rotate freely. When torque is applied, exiting the corner the unit locks and drives both wheels equally. The key benefits of the Detroit Locker, are its rugged construction and superb performance. The only negative is that the automatic lock and unlock operation can create a clunking sensation that can be both felt and heard in the vehicle.

Spool – The spool is the simplest and strongest option, but it lacks differential action, as both axles are joined together by the spool's solid center. Spools are not recommended for the street, as the place high twisting loads on the axles, increase tire wear and can negatively impact handling. Spools are typically only used for drag racing applications where straight-line performance is the only concern.
