Holden RG Colorado LS LTZ Z71 Rear Tailgate Slow Down Strut 2012-2018 — Nitro Struts

Tame your Holden RG Colorado LS LTZ Z71 tailgate with this complete Nitro Struts Easy-Up & Slow-Down assist kit. The factory tailgate is heavy and drops fast — this kit fixes both problems at once, giving you a controlled, gentle drop on opening and a hand-assisted lift on closing.

Installation Notes

Most owners fit this kit in 45–60 minutes with basic hand tools. It's fully bolt-on — no drilling, no cutting. Read the included instructions through once before starting. Park on level ground, fit one side at a time so the tailgate remains supported, and torque the mounting bolts firmly but don't over-do it (these bolt into tailgate sheet metal). If you're not confident, any auto mechanic can fit it in under an hour.

Why Fit This Kit

• Tailgate crashes down when released — risk to legs, dogs, and tools
• You need two hands and a strong back to close the tailgate
• Factory cables are stretched and the tailgate hangs unevenly
• Loading and unloading is a pain you want to fix once
