Skyward Automotive Products SK741578 Rear Driver Side Power Window Regulator and Motor Assembly

The Skyward Automotive Products SK741578 is a rear driver-side power window regulator and motor assembly designed as a direct-fit replacement for select Cadillac, Chevrolet, and GMC trucks and SUVs. This complete assembly addresses a known failure point in the original equipment: cable reel binding caused by insufficient cable tension — a root cause of inoperative power windows in these applications.

This replacement unit incorporates cable tension springs to actively resist cable reel binding, offering an improved design over the original equipment regulator. The assembly includes both the window regulator and the lift motor, so no additional parts are needed for a complete repair.

Key Features:

• Improved design over OEM — features cable tension springs to prevent cable reel binding
• Complete assembly includes both the window regulator and motor
• Bolt-on installation — no special tools required
• Metal and plastic construction built to OEM dimensions and material gauge
• Sold individually (1 per package)
