PROP 65 WARNING:

If you are building a 1st or 2nd gen (1967 thru 1981) pro-touring Camaro or Firebird with RideTech's 4-link rear suspension, then a new Currie Turn 9 Pro-Touring Full-Float Crate Rearend with RideTech brackets installed, is the natural choice

Currie Turn 9® Pro-Touring Rearends, feature a lightweight fabricated 4130 chromoly housing, with windowed internal bulkheads, CNC profiled face flange and .188 wall chromoly tubes, making the housing 30% lighter than a comparably configured fabricated housing – without sacrificing strength or durability

Full-float design improves rear brake performance by eliminating pad knockback during hard cornering and increases safety by maintaining wheel alignment and retention in the event of an axle failure

Available in stock width or narrowed for mini-tubs, Turn 9 Pro-Touring Crate Rearends and are built to match the vehicles stock pinion offset (drive shaft location) and wheel bolt pattern, for a straightforward hassle-free installation

Turn 9 Pro-Touring Rearends are complete, ready to bolt-in assemblies, with a choice of popular differential type, gear ratio, and brake option, making it easy to customize the package to meet almost any need

NOTES:

Lubrication Requirements - 9-inch rearends use a high-offset hypoid gear design that requires a severe duty gear oil with API GL-6 rating. Use of oil not meeting the GL-6 rating will damage the gears and bearings and void the Currie Warranty

4-Link Suspension - This rearend is designed for 67-69 F-body vehicles with RideTech 4-link suspension only.

Aftermarket Brakes - Currie crate rearends conform to the ABCS (Aftermarket Brake Configuration Standard). This allows brake kits that use this standard, to easily be changed or upgraded without having to modify the housing or axles. ABCS brakes use a 2.5” brake space with late-model big bearing Ford housing ends, and a 2.80 center hole in the drum or rotor

Wheel Studs - Currie crate rearends use a standardized-shank Currie Enterprises wheel studs that allow the following wheel studs to be interchangeable in the axles, without drilling: 12mm, 7/16, 1/2, and 1/2 x 3-inch competition

Selecting the right differential for your rearend build is an important decision that will be with you for a very long time - if you get it right. 

Below are short, not-too-technical, overviews of some of the most frequently asked about differential options for Hot Rods, Muscle Cars, and Muscle Trucks.

 

 

       

Detroit Truetrac - Helical-gear limited-slip (worm differential) is the modern replacement for the classic clutch-type posi. Under normal light throttle driving conditions, a Truetrac operates much like a standard open differential, allowing the rear wheels to rotate at slightly different speeds for smooth cornering. However, when accelerating (torque applied), the six helical-gears inside the unit smoothly and quietly engage, applying torque to both rear wheels equally, maximizing traction (think two equal length black stripes). Unlike a traditional clutch-type posi, a Truetrac requires no special oil additive or maintenance. With silky-smooth positive operation and no components to wear out, the Truetrac maintains day-one performance for the life of the unit.

 

 

 

    

 

Trac-Lok/Posi-Trac – Clutch-type limited-slip (Posi), offered as original equipment in many GM and Ford performance cars, these units rely on clutches (friction plates) to transfer power to the wheels. In operation, the clutches slip just enough to allow for smooth cornering while engaging with more force as power (torque) is applied, driving both wheels equally. When used in a daily driver, these units function well; however, as the miles add up or with aggressive driving or track use, the clutches and other internal components will become worn and severely degrade performance. Luckily, rebuild kits are widely available so that these units can be restored to like-new performance. Additionally, if the vehicle sits for extended periods, the clutch plates can stick together, causing the unit to chatter and clunk until gear oil works its way in between the clutch plates. A friction modifier must be added to the gear oil to help prevent the clutches from moaning or chattering during normal driving.
 

 

 

    

Detroit Locker - Automatic "ratcheting-style" differential is known for its reliability, rugged construction, and fully-locked performance on any surface. When power (torque) is applied in either forward or reverse directions, the unit locks both axles together like a spool. When coasting or rolling through a corner (no torque applied), the unequal speed of the inside and outside wheels causes the unit to unlock momentarily, before abruptly locking when power is applied. At the heart of the locker are two, spring-loaded forged steel side plates (one per axle) with large square-edged teeth that engage and disengage a matching center spider block. The interaction of the side plates and spider block teeth creates the signature ratcheting sound of the unit. The Detroit Locker is best suited for off-road or severe track use where maximum traction is required, and quiet/smooth operation is less important.
