Upgrade the aging four-wheel-drive engagement on older Chevrolet and GMC trucks with the Dorman - OE Solutions 4WD Actuator And Wiring Harness Upgrade Kit 600-490. The 4WD systems on many older Chevrolet and GMC trucks use a thermal differential actuator that grows sluggish and can fail as the wax driving its piston ages and deteriorates, ultimately disabling the 4WD system. This kit swaps that dated thermal actuator for a faster-acting electric one. It fits the 1988-1996 Chevrolet K1500, K2500 and K3500, 1992-1996 Chevrolet K1500 Suburban and K2500 Suburban, 1992-1994 Chevrolet Blazer, 1995-1996 Chevrolet Tahoe, plus the matching 1988-1996 GMC K1500/K2500/K3500, 1992-1996 GMC K1500 Suburban/K2500 Suburban and 1992-1996 GMC Yukon — see the Buyer's Guide tab for the full list.

  • Upgraded repair: designed to update a thermally activated differential to a more efficient electric differential on specified Chevrolet and GMC trucks.
  • Complete kit: includes Dorman part number 600-101 4WD electric actuator and part number 600-600 4WD actuator harness — the key components needed to update a 4WD differential.
  • Updated technology: an effective replacement for an old-technology original thermal differential actuator that is sluggish or has failed.
  • Trusted quality: backed by a U.S.-based product team and over a century of automotive experience.
