Gwynn Lewis/KINGPIN Fab –  Coil Spring Isolators (Pair)

The ANR2938 isolators are a 10 mm rubber/metal spring pad designed to remove the harsh metal-to-metal contact between the coil spring and the chassis. Originally fitted to Discovery 1 and Classic Range Rover rears, they work brilliantly on Defenders too—especially where the body is hard-mounted and every vibration is felt inside the cabin.

Fitted to the top of the coil, they cut down axle vibration, reduce road noise, and noticeably smooth out the ride. Many customers report an immediate comfort improvement after installation.

Because they’re a true 10 mm pad, they’re also handy for suspension fine-tuning:

• Use as a 10 mm spacer (front or rear)

• Stack two per spring for ~20 mm lift

• Correct leaning suspension by adding one side only

• Suitable for front coils to reduce harshness

• Works with long-travel setups, but placement must be considered

Sold as a pair.
Fits Defender 90 (front/rear), Defender 110/130 (front), Discovery 1 (front/rear), and RRC (front/rear).

Coil Spring Noise Isolators (Pair)

Stop the coil chatter. Stop the cabin buzz. Drive in peace.

If you’re running progressive-rate coils on your Defender, Discovery or Range Rover, you’ll know the downside: when the close-wound sections touch at ride height, they can transmit a dull vibration or tapping noise straight into the chassis. Annoying on the road, and even worse when idling.

Our Coil Spring Isolators fix that instantly.

What They Do

These isolators slip over the section of the coil where the windings naturally touch. The flexible, impact-resistant material forms a barrier between the coils, eliminating metal-on-metal contact and cutting vibration before it ever reaches the vehicle body.

Inside the isolator is a bonded adhesive strip that grips the spring and keeps the isolator exactly where it needs to be, even under heavy articulation and rough terrain.

How Many You Need

• 1 pair = 2 isolators

• Typically enough for one axle (top OR bottom of both coils).

• If your progressives contact in two places at static height, you may want 2 pairs so you can isolate both the upper and lower sections.

Why Gwynn Lewis/KINGPIN Isolators?

• Made from a flexible, high-durability polymer designed to survive years of compression cycles.

• Can be fitted without removing the coils – simply slip them over the touching section at ride height.

• Designed specifically for Land Rover platforms using progressive-rate springs.
