ACDelco 25751134 Front Coil Spring Insulator OEM GM Replacement

The ACDelco 25751134 is a GM OEM front coil spring insulator designed as a direct factory replacement for select GM vehicles (non-AWD applications). As a genuine GM part, it is built to the same specifications as the original equipment installed at the factory, ensuring a precise fit and reliable performance in your suspension system.

A front coil spring insulator sits between the coil spring and the spring perch, preventing metal-to-metal contact, dampening road noise and vibration, and protecting surrounding suspension components from wear. Replacing a worn or damaged insulator restores ride comfort and helps maintain proper suspension geometry.

• Genuine GM OEM part — designed, engineered, and tested to GM's rigorous quality standards
• Prevents metal-to-metal contact between the coil spring and spring seat
• Reduces suspension noise, harshness, and vibration transfer into the cabin
• Durable rubber construction for long-lasting resilience under load cycling
• Direct OEM replacement — no modification required for installation
• Backed by the GM Replacement Parts Limited Warranty
• Non-AWD applications
