ATP MacPherson Strut Spring Compressor, 300mm Capacity — Forged Acme-Threaded, Safety Lock

The ATP MacPherson Strut Spring Compressor is a heavy-duty, forged spring-compression tool designed to safely compress up to 300mm coil springs for professional suspension work.

This compressor is built for mechanics and advanced DIYers who service MacPherson struts, letting you remove and replace strut cartridges, springs, and damaged components with controlled, mechanical force. It features a robust acme-threaded main shaft, forged hook assemblies, an integrated safety lock, and ships in a convenient storage case (red or blue). Follow proper safety practices—wear eye protection and gloves—and never use an impact driver with this tool.

How do I set up the compressor for a strut spring?

Prepare the unit by lubricating both main shafts, then align the hooks so they slide over the coil with the safety pins backed off. Place the two hook sets opposite each other (180° apart) for balanced compression, then engage the safety locks before turning the shaft.

• Oil both main shafts before first use to ensure smooth movement.
• Back off safety pins so hooks will fit over the spring coils.
• Position hook sets opposite each other for even compression.
• Push safety locks into the locked position evenly on both sides.

What tools and technique are required to compress the spring safely?

Use a 7/8" (or 22mm) socket and a hand ratchet to turn the main shaft; do not use an impact driver. Compress the spring gradually and evenly until you can remove the cartridge fastener nut or other retaining hardware.

• Required: 7/8" or 22mm socket and a hand ratchet (not included).
• Turn shafts steadily and alternate sides to maintain balance.
• Compress only as much as necessary to access the fastener nut.
• Keep hands clear and wear safety glasses and gloves at all times.

What are the key build features and durability points?

The ATP compressor uses forged components and an acme threaded rod for long-term strength and repeatable alignment under load. A built-in safe-lock mechanism secures the hooks during service, while the 300mm compression capacity handles most passenger-vehicle strut springs.

• Forged construction for high tensile strength and durability.
• Acme-threaded main shaft for reliable, smooth compression.
• Integrated safe-lock on each hook to prevent accidental release.
• 300mm compression range suitable for common MacPherson springs.

Who is this for: The ATP MacPherson Strut Spring Compressor is intended for professional technicians, automotive repair shops, and experienced home mechanics comfortable with suspension work and safety protocols. It is not a consumer toy—professional skill, the correct ratchet/socket, personal protective equipment, and adherence to the provided setup steps are required. Always avoid power impact tools with this unit and follow the locking procedure to minimize risk.
