Energy Suspension 4.6101G Rear Spring Isolator

Used for lowering spring installation, for mine were wore out.

These items are a lot beefier than the last ones installed on this vehicle. should last longer also.

Product comes packaged with two isolator sets per box. Size was a perfect fit for the rear springs on a 2001 Mustang Base. The material appears to be heavy duty, has some pliability and has a smooth finish that is slick to the touch. As the springs were being installed the slick finish allows the spring to be rotated into final position while lightly loaded. As the spring became fully loaded the springs stayed firmly in place and after a few weeks there is no sign of extrusion of the plastic .

Exact fit

Great deal and quality can’t wait to add these with my rear end build!

They fit my application, 99 Mustang, as advertised. Appear to be good quality, and silenced my squeaky rear coils. Fit and did what I wanted, and what they are supposed to do. What more is there?

Perfect for in aftermarket springs for a 2004 Mustang GT

Perfect replacement for the damaged or missing rear coil spring isolators in your Fox/SN95 Mustang. Much better ride with these installed vs the dead rubber parts, real reduction in road noise felt through the floor. The only thing to be aware of is these will increase the rear ride height by 1/4"+ when new, especially if your rubber isolators were really worn or missing altogether. They do 'squish' a little over time, but something to keep in mind when you install these.
