Westar ST-3940 Suspension Strut Mount - Rear Left

Westar ST-3940 Rear Left Strut Mount

Westar ST-3940 is a suspension strut mount built for the rear left position on select Kia Sephia models. It supports suspension rotation, helps secure the strut to the body, and adds noise isolation for a quieter ride.

• Provides a pivot point for suspension movement to maintain proper steering dynamics and reduce tire and component wear
• Locks the strut and body together for a secure upper mounting point
• Includes a noise-dampening design to reduce road noise and vibration transfer into the cabin
• Built with application-specific materials and a protective finish for durability

Fitment Details

Compatible with 2001 Kia Sephia, rear left. Compatible with 1995-1999 Kia Sephia, rear left. Compatible with 2000 Kia Sephia, rear left, before 6/00.

This part cross-references Monroe Shocks & Struts 903940 for the same application.

What It Helps Address

• Clunking or knocking from the rear suspension mount area
• Excess vibration or road noise entering the cabin
• Loose or worn upper strut mounting support
• Imprecise suspension movement that can affect tire wear
• Reduced stability from a deteriorated rear left strut mount

Installation Notes and Tips

Install ST-3940 at the rear left position only on the listed Kia Sephia applications. Verify the vehicle build date for 2000 models, since this part applies to vehicles built before 6/00. Inspect the surrounding strut components, spring seat, and mounting surfaces before installation.

Quality Assurance

Westar designs this strut mount with application-specific materials and a finish intended to support long service life and consistent fitment on the listed Kia Sephia applications.
