Whiteline Rear Differential Front Support Bushing — Subaru Impreza GC/GD/GG (incl. WRX/STI)

Reinforces the soft factory rubber bushing at the rear differential's front support. The stock rear end on WRX and STI models suffers from excessive play and the notorious 1-2 upshift clunk — this kit locks it up.

Key Benefits

• Reduces rear-end float, especially under acceleration
• Removes drivetrain slap on hard gear changes
• More precise handling and chassis response from the rear
• Recommended for high-power builds, drag and circuit work

Limited lifetime warranty. Note: this part will induce some additional NVH — expected given it bypasses factory compliance.

Fits Subaru Impreza GC/GD/GG including WRX (2002–2007) and STI (2004–2007), plus Forester SF/SG.
