Based on the provided sources, Toyota Highlander and Toyota Grand Highlander liners are not interchangeable. They are distinct vehicles with unique floor layouts that require completely different custom-fit product lines. The newer generation (2020–2025) of the standard Toyota Highlander uses the SA0500 product line. In contrast, the Toyota Grand Highlander and Grand Highlander Hybrid models require the entirely separate SA0719 product line. Because Smartliner products are meticulously engineered using laser-scanning technology to perfectly match a specific vehicle's exact floor layout, the liners for the standard Highlander will not fit the floor geometry of the Grand Highlander, and vice versa.

Feature List:

• Not interchangeable between standard Highlander and Grand Highlander
• Different product lines (SA0500 vs SA0719)
• Unique floor pan and cargo area dimensions
• Grand Highlander has specific SmartTrim™ features
• Separate cargo liners for subwoofer-equipped models
• Always select your exact model when ordering
