OS Giken 07/01 - 09/04 Honda DC5 Integra K20A (MT Only) Super Lock LSD

The OS Giken Super Lock LSD (HA081-HA) delivers a 1.5-way cam and clutch plate limited slip differential built for 2001-2004 Honda DC5 Integra Type R K20A manual transmission models. It bolts directly into 2002-2004 Acura RSX Base and Type-S plus 2002-2003 Honda Civic Si for even power transfer to both drive wheels. Drivers gain sharper corner exits, reduced wheelspin, and confident handling on track or street.

Key Features

  • Twin Cam Design: Distributes axial thrust evenly across 12 clutch plates for smooth progressive lockup and throttle-sensitive response
  • 1.5-Way Operation: Full lockup under acceleration at 52-degree ramp angle with 38-degree deceleration for balanced control
  • High-Strength Clutch Plates: Sintered metal construction handles over 450Nm torque capacity with extended durability under racing loads
  • Preload Adjustment: Shim kit allows 85-115 kgf-cm initial torque tuning to match suspension, tire setup, or driving demands
  • Precision Gears: 27-tooth side gears and 23-tooth pinions matched to 4.928 final drive for quiet operation and zero-speed power delivery

Product Notes

  • Manual transmission only, open differential replacement with no case modifications
  • Fill with 1.6L OS Giken LSD oil after 30-minute break-in drive then re-fill for peak function
  • Heavy precision component, handle with care during unpacking

Installation Notes

  • Professional installation recommended.
  • Remove OEM differential carrier, transfer ring gear, and install new unit with OEM bolts torqued to 74 Nm
  • Uses stock axle shafts, CV joints, and differential mounts

Differentials

Differentials

Differentials distribute engine torque between drive wheels, allowing them to rotate at different speeds through corners while maintaining traction. Upgrading from a factory open differential to a limited-slip or locking differential is one of the most impactful drivetrain improvements you can make for towing, off-roading, drag racing, or any application where both wheels need to work together under load.Popular Differential UpgradesTop upgrades include Eaton Detroit Locker and Eaton Truetrac limited-slip units for GM, Ford, Dana, and Chrysler axles, ARB Air Lockers for Jeep and truck off-road applications, and OS Giken Super Lock LSD units for JDM performance platforms. Locker conversions for Dana 44 and Dana 60 front axles are essential for serious rock crawling, while Truetrac helical LSDs deliver traction improvements without aggressive locking behavior for street and tow applications.What is the difference between a locker and a limited-slip differential?A locking differential ...
