BILITOOLS Macpherson Spring Compressor Tool, Heavy Duty Coil Spring Kit

The BILITOOLS Macpherson Spring Compressor Tool is designed to compress automotive coil springs during the replacement or servicing of struts, springs, bearing seats, and top mounts. Its broad opposing fork jaws help keep the load centered and evenly supported throughout the process. The set includes three interchangeable jaw pairs that handle spring outside diameters ranging from 2.6 to 4.9 inches (65-125 mm), 3.4 to 6.5 inches (88-165 mm), and 4.9 to 8.3 inches (126-212 mm).

Built from one-piece forged 45 steel, the heat-treated jaws resist deforming under high pressure, delivering a maximum load capacity of 5,512 pounds with one fork pair installed. To help protect painted or coated springs from cosmetic damage, the tool features smooth, burr-free edges and includes six red protective sleeves. When working with conical springs, an included square spacer allows you to balance different upper and lower coil diameters.

Operation requires a standard 22 mm wrench or socket to drive the threaded compression rod steadily, with hand-tool operation recommended. Before putting the tool to work, you will need to inspect and lightly lubricate the threads. Note that this specific version is designed exclusively for clockwise-wound springs, so you must verify the coil winding direction before starting, as driver-side and passenger-side springs can vary.

One major consideration is that this kit will not work on counterclockwise-wound coils, which require a dedicated left-hand variant. Additionally, the required 22 mm wrench or socket is not included in the box, meaning you must supply your own hand tools. The tool also requires routine manual maintenance, as threads should be checked and lubricated prior to every use.

Verdict: This heavy-duty kit is an excellent choice for home mechanics and technicians who service standard clockwise-wound MacPherson struts across various vehicle sizes. Its strong 5,512-pound rating, multiple jaw sizes, and protective sleeves make it a reliable and versatile tool for strut assembly work.

• Small Jaw Range: Ø2.6–4.9 in (65–125 mm) outside diameter
• Medium Jaw Range: Ø3.4–6.5 in (88–165 mm) outside diameter
• Large Jaw Range: Ø4.9–8.3 in (126–212 mm) outside diameter
• Spring Direction Compatibility: Clockwise-wound springs
• Required Drive Tool: 22 mm wrench or socket (not included)
• Included Accessories: 1 threaded rod, 3 jaw pairs, 6 protective sleeves, 1 square spacer, 6 socket-head cap screws, carrying case

A great fit if you:

• Need to service or replace MacPherson struts, top mounts, or bearing seats on standard clockwise-wound springs.
• Work on a variety of vehicles with spring diameters between 2.6 and 8.3 inches.
• Want built-in protection against scratching coated coil surfaces during compression.
• Service conical springs that require an adapter spacer for uneven coil widths.

Consider something else if you:

• Need to compress counterclockwise-wound coil springs.
• Do not have a 22 mm wrench or socket readily available in your toolbox.

How do I check if my spring is compatible?
Place the upper coil end at the 12 o clock position and follow the direction of the first turn. This tool fits clockwise-wound springs; counterclockwise-wound springs require a left-hand variant.

What drive tool is required to operate this compressor?
It requires a standard 22 mm wrench or socket, and manual hand-tool operation is recommended. The wrench or socket is not included in the kit.

What spring sizes does this kit accommodate?
The three interchangeable jaw pairs cover spring outside diameters of 2.6 to 4.9 inches (65-125 mm), 3.4 to 6.5 inches (88-165 mm), and 4.9 to 8.3 inches (126-212 mm).

Can this tool compress conical springs?
Yes, you can use the included square spacer to accommodate springs with differing upper and lower coil diameters.
