Product Description

Z1's Frontier / Xterra Rear Differential Locker Harness Extension adds a crucial 10 inches of length between your vehicle's body harness and locker sub-harness. Designed specifically for Nissan Frontier and Xterra models, this simple yet essential upgrade protects your rear locker system from damage when running moderate suspension lifts, body lifts, or longer-travel rear shocks.

Without it, full suspension droop can stretch the locker harness to the breaking point, risking torn wires, broken solenoids, and a disabled rear locker—right when you need it most. Keep your rig's locker functional and your adventures worry-free with this easy-to-install extension.

Features:

  • Adds 10" of Extra Length
  • Essential for Lifted Vehicles
  • Plug-and-Play Installation
  • Fits The Factory M226 E-Locker
  • OEM-Style Fit and Finish

Fits:

  • 2005-2015 Nissan Xterra
    • Pro4X & Off-Road Models
  • 2005+ Nissan Frontier
    • Pro4X and NISMO Models

What our customers say

This is as easy as unplugging one harness and plugging the extension in. This will gain you about 6-8 inches of length which is plenty for all lifted Frontiers. My own truck has a 3 inch lift and I no longer have any worries about the harness being to short.
