Salior 2PC Coil Spring Spacers for 5–5.5" Springs — Thick Rubber Boosters to Raise Ride Height, Reduce Vibration

Salior 2PCS Coil Spring Spacers are thick rubber boosters that fit 5–5.5" coil springs to raise ride height, firm up spring rate, and reduce vibration and noise.

These universal coil spring spacers slip into a vehicle's coil springs to provide immediate extra support without replacing the entire spring. Molded from a single-piece, wear-resistant rubber, the spacers add a stable cushion between coils to limit sag, dampen vibration, and improve weight distribution for many sedans, SUVs, and light off-road vehicles. They’re designed for springs with an outer diameter of 5 to 5.5 inches and are simple to install when proper tools and safety procedures are used.

How do these spacers change driving feel and handling?

Installing the Salior spacers shortens the working travel between coils, effectively increasing the spring rate so the suspension resists compressing under load. That firmer response helps control rear sag and reduces bottoming on heavy loads or when towing. The rubber construction also isolates and soaks up high-frequency vibrations that can cause rattles and road noise.

• Increases effective spring rate for firmer suspension response
• Helps reduce rear-end sag under weight
• Dampens vibration and reduces chassis noise
• Improves stability during cornering and load changes

Will these spacers fit my vehicle and how are they sized?

Salior spacers are made for coil springs with an outer diameter between 5.0 and 5.5 inches. The spacer measures 6.28 inches outer diameter, 4.24 inches inner diameter, 1.62 inches wide, with a spring track width of 0.9 inches—dimensions chosen to suit a wide range of passenger cars and light trucks. They’re universal in design but always confirm your spring OD before purchasing.

• Compatible with springs OD 5.0–5.5 inches
• Overall OD 6.28", ID 4.24", width 1.62"
• Spring track width: 0.9" for secure seating
• Works with many sedans, SUVs, and light off-road vehicles

How durable are these rubber spacers and what conditions can they handle?

The spacers are produced by one-piece molding from a robust rubber compound to resist wear, cracking, and permanent deformation under normal driving conditions. That construction gives a longer service life compared with thinner or glued-layer designs. They’re engineered to tolerate daily use, moderate off-road exposure, and temperature swings encountered in typical driving.

• One-piece molded rubber to resist splitting and wear
• Maintains shape under repeated compression cycles
• Resists vibration-related degradation and noise generation
• Suitable for everyday driving and light off-road use

How hard is installation and what tools are needed?

Installation requires lifting the vehicle and compressing the coil spring so the spacer can be inserted following the spring’s helix. The product slides in along the spiral, and a spring compressor or appropriate suspension tool ensures safe, full seating. While the process is straightforward for experienced DIYers, we recommend professional installation if you’re not familiar with suspension work.

• Lift vehicle and secure on stands before beginning
• Compress spring and insert spacer along the coil spiral
• Use a spring compressor or professional tools for safety
• Check seating and torque suspension fasteners after installation

Who is this for: Salior coil spring spacers suit drivers who need a cost-effective way to level a vehicle, reduce rear sag, or sharpen suspension response without replacing springs. They’re ideal for owners of sedans, crossovers, and light-duty trucks seeking improved load handling, quieter rides over rough pavement, and a simple, reversible upgrade that preserves original springs when done correctly.
