OwnMy Rubber Coil Spring Spacers 4PCS 1.5" Lift Round Boosters for 5"–5.5" Springs, Reusable Molded Rubber

OwnMy 4PCS Rubber Coil Spring Spacers are durable, 1.5-inch-high round rubber boosters that fit coil springs with a 5"–5.5" outer diameter to add lift and improve load handling.

These four rubber coil spring spacers from OwnMy are made to increase rear ride height, reduce rear sag when carrying loads, and raise the effective spring rate without replacing your suspension. Built from a single-piece molded rubber compound, each spacer measures 6.3" OD, 4.2" ID, 0.8" spring track width and 1.5" total height. They are reusable, easy to trim for fine adjustments, and compatible with many passenger cars, SUVs, light trucks and campers — check your spring outer diameter (5"–5.5") before ordering.

How do these spacers change vehicle stance and load capacity?

Adding the OwnMy coil spacers places rubber directly between coils to slightly compress the spring assembly and raise the vehicle’s rear. That increases the spring’s load-bearing capacity and reduces sag when hauling cargo or towing. Effects are progressive: you gain modest lift plus firmer rear response without altering front geometry.

• Provides approximately 1.5 inches of lift at each spring location.
• Increases effective spring rate for better load support.
• Helps restore level stance when the vehicle is loaded or towing.

What are the exact dimensions and fit requirements?

Each spacer has an outer diameter of 6.3" and an inner diameter of 4.2", designed to accept coil springs with an outside diameter between 5" and 5.5". The track width that receives the coil is 0.8" and the spacer height is 1.5". Always confirm your spring OD before purchasing to ensure the spacer seats securely.

• Outer diameter (OD): 6.3".
• Inner diameter (ID): 4.2"; fits spring OD 5"–5.5".
• Spring track width: 0.8"; total height: 1.5".

How durable and adjustable are these rubber boosters?

The OwnMy spacers use a robust integrated rubber compound engineered for repeated use and resistance to tearing or cracking under normal driving conditions. They are flexible enough to trim for small spring-rate adjustments, and their one-piece design minimizes separation or failure points. Expect consistent performance on rough roads and during frequent loading cycles.

• Molded single-piece rubber resists wear and deformation.
• Can be cut shorter to fine-tune lift or spring rate changes.
• Designed to withstand regular driving and load variations.

How easy is installation and what tools are needed?

Installation is straightforward for someone familiar with basic suspension work: lift the vehicle, compress the coil spring enough to create space, and insert the spacer into the spring seat so it nests in the coil. A spring compressor or suitable jack and safety stands are recommended for safe, controlled work. After installation, verify the spacer is fully embedded and the vehicle sits level on flat ground.

• Lift vehicle and secure on jack stands before starting.
• Compress the spring with a proper tool to insert spacer safely.
• Confirm spacer is seated and recheck ride height after lowering.

Who is this for: OwnMy 4PCS Rubber Coil Spring Spacers are suited for vehicle owners who want a simple, reversible way to reduce rear sag, gain modest lift, or firm up the rear suspension without replacing springs. They’re ideal for drivers of cars, SUVs, light trucks and campers that have coil springs with a 5"–5.5" outer diameter and need improved level stance or extra load support for towing and hauling. If you require large lift kits or total suspension redesign, consider specialized shocks or spring replacements instead.
