The frameless window design of the 300ZX makes the upper window slider notorious for failing. This slider is responsible for keeping the window stable and secure, so when it fails, the window will rattle (especially while it's half-way down). This is also a common cause for water leaks into the cabin, as a bad window slider means there's nothing to snug the glass up against the weather strippings on the A-pillar and T-Tops.

This kit contains all the hardware relating to the upper slider, including:

• Upper Window Slider Bolt
• Upper Window Slider
• Slider Cap
• Slider Inner Washer
• Slider Outer Bushing
• Window Bushing Spacer

We also carry a more basic kit, which includes just the slider and bolt, here.

One kit covers on side; two required per vehicle.
