Identifying Titan King Cab Rear Vent Glass Variations
When sourcing replacement side glass for this truck, the cab configuration dictates the exact part needed because the four-door Crew Cab does not use a separate vent or quarter panel at all. On the Crew Cab, the rear doors use standard full drop-down windows under NAGS number FD22216. If your truck is a King Cab equipped with the reverse-opening rear suicide doors, that stationary pane set into the rear door frame is categorized in auto glass catalogs as the rear vent or cab quarter glass.
Before ordering or fitting the glass, I verify the factory tint level to prevent a mismatched appearance between the front roll-down windows and the rear cab glass. Nissan shipped these King Cabs with two distinct tint options:
| Cab Trim Level | Tint Type | LH Part Reference | RH Part Reference |
|---|---|---|---|
| Base XE | Green Solar (Clear) | OEM 82301-7S200 | OEM 82300-7S200 |
| SE, LE, SV, PRO-4X | 20% Dark Privacy | NAGS FQ21948 YPN / OEM 82301-7S210 | OEM 82300-7S210 |
The PRO-4X, SE, and LE models almost universally carry the deep 20% privacy glass, while basic fleet-style XE models rely on the lighter green solar shade. These stationary units are completely passive; they do not incorporate defroster grid lines, embedded radio aerials, or opening latches, but they do arrive molded into a dedicated perimeter sash frame that fastens directly into the King Cab door shell.
Critical Fit Factors on the Rear Suicide Door Shell
The rear door on the King Cab utilizes a wide-swing hinge mechanism that opens nearly flat against the truck bed, which exposes the window frame to substantial leverage, body twist, and turbulent airflow at highway speeds. Nissan trucks of this era were prone to high-speed wind whistling around the exterior sash moldings (frequently highlighted in technical service bulletin NTB19-102), making precision seating essential during replacement.
Once you book a replacement for your truck, I can typically be on-site at your driveway within roughly an hour to handle the job. Before the new aftermarket unit is positioned, I examine the integrated outer sash molding and rubber weatherstrip run channel. The lower door latch mechanism sits directly beneath this opening inside the door cavity, meaning any misaligned seal will direct rain run-off onto the interior door locks rather than out through the cab bottom drains.
Post-Replacement Inspection Checklist for Titan Owners
After the rear quarter glass has been renewed on your King Cab, take a few minutes to inspect the door assembly using this punch list:
- Outer sash molding flushness: Sight down the exterior cab seam from the front door edge to the rear box to verify the glass molding sits flat against the sheet metal with no lifting corners.
- Tint level consistency: Compare the LH or RH quarter glass against the adjacent rear cab slider or solid back glass to confirm the replacement privacy level matches the factory 20% dark tint rather than clear XE green.
- Inner door trim alignment: Ensure the interior door panel sits tight along the lower glass channel without bulging away from the metal frame.
- Door latch clearance: Cycle the exterior and interior suicide door release handles to confirm the inner latch linkage operates smoothly without binding against the lower glass sash mounting points.
- Acoustic seal check: Take the truck up to highway cruising speed to confirm there is no high-pitched air rush or whistling along the vertical glass weatherstrip channel.
