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
