Salior Coil Spring Spacers 2PC for 5–5.5" Springs — Thick Rubber Boosters for Lift, Vibration Damping

Salior 2PCS coil spring spacers are heavy-duty rubber inserts that lift and stiffen 5–5.5" coil springs to improve ride height, reduce sag, and dampen vibration.

These Salior coil spring spacers are designed as a low-cost, reversible way to restore vehicle rake, add a slight lift, and improve spring response without replacing the entire suspension. Molded from thick, wear-resistant rubber in one piece, each spacer nests into the coil to increase spring rate, limit excessive travel, and help quiet chassis noise on uneven roads. The spacers fit springs with an outer diameter of roughly 5 to 5.5 inches and feature a wide track and snug inner cup to keep the spring seated.

How does this spacer change ride height and handling?

Installing the Salior spacer adds a small lift and raises the static spring perch, which reduces rear sag and can correct uneven stance. Raising the spring preload slightly firms the initial portion of the spring curve, improving stability during cornering and when carrying loads.

• Restores a few centimeters of height to sagging rear ends.
• Increases spring rate at low travel for crisper response.
• Helps maintain level stance under light loads or towing.

Will these spacers reduce noise, vibration, and harshness?

Yes — the thick rubber construction isolates metal-to-metal contact and absorbs some of the spring’s energy, which lessens vibration and reduces the clatter associated with loose or worn suspension parts. That can make driving on rough surfaces noticeably smoother and quieter.

• One-piece molded rubber reduces chattering and clunking.
• Limits excessive spring arc to reduce scraping noises.
• Improves ride comfort on broken pavement and gravel roads.

Are these spacers compatible with my vehicle and how do I install them?

Salior spacers are universal for coil springs with an outer diameter between 5 and 5.5 inches; dimensions are OD 6.28", ID 4.24", width 1.62", and spring track width 0.9". Installation requires lifting the vehicle, compressing the coil enough to insert the spacer along the helix, and seating the spring fully into the spacer — professional installation is recommended if you’re inexperienced.

• Fits most sedans, SUVs, and light off-road vehicles with 5–5.5" OD coils.
• Basic installation: lift vehicle, compress spring, insert spacer, release carefully.
• Recommended to torque check and inspect after first 100 miles of driving.

How durable are these rubber spacers under daily driving conditions?

Manufactured from durable, abrasion-resistant rubber using one-piece molding, these spacers resist deformation and cracking under normal use. They’re built to tolerate the repeated compression cycles encountered in daily driving, though extreme off-road abuse or severe load conditions will still accelerate wear.

• Thick molded rubber resists wear and tearing.
• Retains shape under repeated compression cycles.
• Not intended as a permanent replacement for damaged springs or struts.

Who is this for: The Salior 2PCS coil spring spacers are ideal for drivers wanting an economical fix for rear sag, light lift for clearance, or improved low-speed spring response without replacing springs or adding a full suspension kit. Suitable for owners of sedans, crossovers, small SUVs, and light trucks whose coils measure roughly 5–5.5 inches OD, and for DIYers comfortable with basic suspension work or for installers offering quick, reversible upgrades.
