ATP MacPherson Strut Spring Compressor — forged 300mm capacity, acme-threaded shaft & built-in safety lock

The ATP MacPherson Strut Spring Compressor is a forged, professional-grade tool designed to compress up to 300mm coil springs safely for strut service and replacement.

This tool lets mechanics and experienced DIYers remove and install MacPherson strut springs by providing controlled, even compression and a built-in safety lock. It features heavy-duty forged components, an acme-threaded main shaft for reliable force control, and a durable storage case. Read the setup and safety guidance carefully before use—improper handling can cause serious injury.

How do I prepare the compressor before use?

Preparation reduces binding and improves safety. Lubricate both main shafts, inspect hooks and locks, and make sure the set fits the spring diameter you will work on. Never use an impact driver with this tool.

• Lubricate both main shafts with light oil to ensure smooth operation
• Check hooks, safety pins and locks for wear or damage before each use
• Back off safety pins to align hooks over the spring before positioning
• Use only a 7/8" (22mm) socket and ratchet—do not use an impact wrench

What is the correct way to position and compress a strut spring?

Correct positioning balances the load and prevents bending or slippage. Mount the hook sets opposite each other at 180°, engage the safety locks evenly, and compress slowly until the spring is relieved from the top nut.

• Place both hook assemblies 180° apart and opposite each other on the spring
• Fit hooks over the coil with safety pins backed off for easy placement
• Push safety locks into the locked position with even pressure on both sides
• Use a 7/8" or 22mm socket and ratchet to turn the main shaft gradually

Which features improve safety and durability?

This compressor combines robust construction with fail-safe elements to reduce risk during service. The forged body and acme thread give predictable compression, and the built-in safety locks hold the hooks in place while you work on the strut cartridge.

• Forged construction and acme-threaded main shaft for long-lasting strength
• Built-in safety lock mechanism to secure hooks during compression
• Capacity to compress coil springs up to 300mm for most passenger vehicles
• Comes with a storage case (color may be red or blue) for organized transport

What precautions should I follow to avoid injury?

Compressed springs store a lot of energy; careless handling can cause severe injury. Wear safety glasses and gloves, compress evenly on both sides, and never substitute power tools that deliver sudden torque.

• Always wear safety glasses and heavy-duty gloves when compressing springs
• Do not use an impact driver or impact wrench—use a hand ratchet only
• Compress slowly and evenly until the cartridge retaining nut can be removed safely
• Ensure the safety locks are engaged before loosening any strut fasteners

Who is this for? The ATP MacPherson Strut Spring Compressor is built for professional technicians, automotive repair shops, and experienced home mechanics who service MacPherson struts. It’s intended for users comfortable with suspension disassembly and who will follow the tool’s safety procedures. If you lack experience with high-tension springs, seek professional assistance rather than attempting strut service alone.
