Rear Upper Coil Spring Seat for Saturn Ion

MasterPro 4713451 is a specific-fit rear upper suspension coil spring seat for select Saturn Ion models. It uses polyfoam construction with an included insulator to help restore proper spring seating and rear suspension isolation on the vehicle.

  • Specific-fit suspension coil spring seat for the rear upper position
  • Polyfoam construction with black finish
  • Insulator included for added spring isolation
  • Standard replacement grade for OE-style service
  • Meets or exceeds original equipment manufacturer specifications
  • Per-vehicle quantity: 2

Detailed Description

This MasterPro suspension coil spring seat, part number 4713451, is built for rear upper spring support on Saturn Ion applications. It is a direct replacement component for 2006-2007 Saturn Ion models with 15" wheels and 2003-2005 Saturn Ion models without 16" wheels. The polyfoam design and included insulator help maintain proper spring positioning and reduce contact-related noise at the rear suspension.

This part cross-references KYB SM5355 and MOOG Chassis Products K6684 for the same application. If you are replacing worn rear spring seats on a Saturn Ion, 4713451 provides a standard replacement solution that matches the specified fitment and OE-level requirements.

What It Helps Address

  • Worn or compressed rear upper coil spring seat material
  • Noise from spring-to-seat contact in the rear suspension
  • Loss of proper spring support at the rear upper mount
  • Degraded isolation from aged or damaged insulator material
  • Uneven rear suspension seating on Saturn Ion models

Installation Notes and Tips

Install this part in the rear upper position only and verify wheel-size-specific fitment before ordering. Compatible With 2006-2007 Saturn Ion, rear upper, 15" wheels, and 2003-2005 Saturn Ion, rear, without 16" wheels. Replace in pairs when servicing both sides of the rear suspension, since the vehicle quantity is 2. Confirm the spring seat orientation and inspect adjacent suspension components for wear during installation.

Quality Assurance

MasterPro 4713451 is a standard replacement part that meets or exceeds original equipment manufacturer specifications for the listed Saturn Ion applications.
