Powertrax; Lock-Right Locker; 10 Bolt Positive-Locking Differential; 8.5" Ring Gear; 28 Spline Axle; Open Case

If you're looking for extreme traction, Classic Industries® has got it all locked up! This new positive-locking differential is a breakthrough in differential technology, delivering the most traction possible while still providing full differential operation! The Lock-Right™ system offers a revolutionary design that is exceptionally rugged and yet ingeniously simple!

Just replace the existing spider gears with a pair of Lock-Right™ driver and coupler gears in your existing stock, open differential assembly. Installs in 1-2 hours and Lock-Right™ doesn't require extra modification or set up since the ring and pinion gears are unaffected. Best of all no special tools, calibration equipment or fixtures are needed!

Designed for fail safe operation and manufactured from high strength, ultra-resilient, heat tempered steel alloys for maximum toughness. Prevents wheel "spin-up", and delivers traction that puts the power down with maximum efficiency. Give your classic the extra performance edge you deserve at a price that can't be beat!

Made in USA

Note: The Lock-Right provides maximum traction, but a light clicking noise can be heard when turning as the Lock-Right gears allow for wheel differentiation. On some vehicles the engine noise will overcome the clicking noise.
