Universal Coil Spring Spacers

Nolathane coil spring spacers offer a simple, cost-effective way to fine-tune ride height on coil-sprung 4WDs, pick-ups and passenger cars. Fitted at the spring seat or strut top, they add a small, controlled amount of height to correct a lean, level a vehicle after fitting accessories, or restore clearance without replacing the springs.

Each listing shows the spacer type, fitting position and height change for its application, so you can choose the coil spacers that match your vehicle and the result you want.

Understanding Coil Spring Spacers

A coil spring spacer is a firm pad or disc that sits between the coil spring and its seat, or between the strut assembly and the body. By adding material at that point, it raises the body relative to the axle or control arm without changing the spring itself. Because the spring is unchanged, its rate and the way it supports load stay the same; only the static ride height moves.

Coil spacers are used on solid-axle 4x4s, independent front suspension (IFS) strut setups and coil-sprung rear ends on passenger vehicles. The principle is the same in every case: a measured increase in height at a precise, located mounting point.

Types of Coil Spring Spacers

Spring Seat Spacers and Pads

These fit at the upper or lower spring seat and locate on the spring and perch. Some are designed to add height, while others restore the original height when a perished factory rubber pad is replaced.

Strut Top Spacers

On coil-over-strut suspensions, spacers can fit between the strut top mount and the body tower. These raise the front of the vehicle without dismantling the strut assembly.

Spring Insulators

Insulators sit between the spring and its seat to reduce noise and protect the seat from wear. Polyurethane replacements restore the correct spring location and height where the original rubber has deteriorated.

Reasons to Fit Coil Spacers

Coil spring spacers are best suited to modest, targeted height changes. Common reasons include:

• Levelling a 4WD that leans to one side because of long-range fuel tanks, drawers, water tanks or other permanently mounted equipment.
• Correcting front-to-rear stance after fitting a heavier bullbar and winch, or a canopy or tray.
• Gaining a little clearance for slightly larger tyres or improved approach and departure angles.
• Restoring height after replacing deteriorated factory spring pads or insulators.
• Fine-tuning ride height when an existing suspension setup sits slightly lower than intended.

Pros and Cons of Coil Spring Spacers

Spacers are useful when used for the right job, but they have limits. Understanding both sides helps you decide whether a spacer or a spring change is the better choice.

Advantages

• A low-cost way to adjust ride height without buying new springs.
• Keeps the existing spring rate, so ride comfort and load support stay much the same.
• Reversible, making them suitable for fine-tuning or as a stage in a larger build.
• Quick to fit on many vehicles, particularly at the strut top or spring seat.
• Allows side-to-side correction where one side carries more fixed weight.

Disadvantages

• They do not increase load capacity. A vehicle that sags under regular heavy loads needs springs rated for that load, not spacers.
• They do not fix sagging springs. Tired springs should be replaced rather than packed out.
• Raising ride height reduces available down-travel (droop) because the shock absorber?s length has not changed, which can affect articulation off road.
• On IFS vehicles, extra height increases CV joint and upper ball joint angles, which can accelerate wear.
• Height changes alter wheel alignment, so camber, caster (castor) and toe must be re-checked and set.
• Brake hoses, ABS sensor wiring and shock absorbers must still have enough length at full extension.

Choosing Quality Coil Spacers

Not all spacers are equal. The material, design and fit determine whether a spacer performs reliably or becomes a problem.

A good spacer must locate positively on the spring, seat or strut tower so it cannot move or fall out when the suspension unloads. It must be made from a material that holds its thickness under constant load rather than compressing over time, and it must suit the exact spring end and seat profile of the vehicle. Generic, one-size-fits-all spacers that sit loosely on top of a coil can shift and alter geometry, and may cause problems at inspection.

Polyurethane is well suited to this job. It offers high load-bearing capability, abrasion resistance and tensile strength, along with resistance to oil, grease, ozone and weathering. It holds its shape under constant load and isolates the spring from the body better than metal spacers, helping reduce noise and vibration.

Fitting Coil Spring Spacers

Spring seat spacers usually require the spring to be removed. On solid axles this can mean lowering the axle with the vehicle securely supported; on strut suspensions it means removing the strut assembly and using a proper spring compressor. Never attempt to dismantle a strut without the correct compressor, as the stored energy in a coil spring can cause serious injury.

Strut top spacers fit between the top mount and the tower, often using longer studs or bolts to maintain correct thread engagement. Check every fastener is torqued to the manufacturer?s specification.

After fitting, check clearances at full suspension extension and compression, including brake hoses, sensor wiring, the shock absorber, the tyre and wheel arch, and the coil spring against the control arm. Finish with a full wheel alignment (tracking) and check headlight aim if the front height has changed.

Legality and Compliance

Coil spring spacers are not banned outright, but every suspension change must keep the vehicle safe and within the standards that apply where it is registered.

In Europe, suspension modifications are assessed at the periodic roadworthiness inspection, and some countries require approval for changes to ride height. In every region, tell your insurer about any change to the vehicle?s suspension or height.

Nolathane Polyurethane Expertise

Nolathane has been making polyurethane suspension bushings since 1974, originally developed to replace brass bushes in hillclimb competition. More than 50 years on, Nolathane polyurethane is produced in a range of durometers (hardness grades), each selected for its application. For spring pads and spacers, that means a material firm enough to hold height under constant load while still isolating the spring from the chassis. Combined with superior elasticity, memory and outright durability, the signature red components give mechanics and DIY owners a dependable way to repair, restore and upgrade their suspension.
