Acymner Coil Spring Compressor 14" — 14" Jaw Internal Strut Remover/Installer, Heat‑Treated Steel, 1/2" Drive

Acymner 14" Coil Spring Compressor is a heavy‑duty internal strut remover and installer set that safely compresses automotive coil springs up to 15" using heat‑treated steel jaws and a 1/2" drive ratchet connection.

This professional‑grade internal spring compressor is engineered for routine suspension work on cars and light trucks. Built from heat‑treated, high‑strength steel and supplied as a pair, the tool clamps inside coil springs and pulls them inward so you can remove or install struts and shocks with control. Its 14" maximum jaw opening and compatibility with springs up to 15" long make it a practical addition to a home garage or a busy shop.

How does the Acymner compressor make strut removal safer?

By compressing the spring from the inside, the tool reduces outward tension on the coil and gives you stable, centered control while loosening or tightening strut hardware. The hooked jaws grip coils securely to minimize slippage and sudden releases when compared with less robust methods.

• Heat‑treated steel jaws resist bending under load.
• Hooked clamp profile engages coil winds, preventing slip.
• Paired units allow even compression from both sides of the spring.
• 1/2" drive interface lets you use a controlled ratchet or breaker bar.

Which vehicles and spring sizes work with this tool?

The set is designed for most passenger cars and light trucks that use internal‑style coil springs. It handles springs up to 15" in uncompressed length and provides a 14" maximum jaw spread to accommodate a wide range of diameters.

• Compatible with many OEM coil springs and aftermarket strut assemblies.
• Maximum jaw opening: 14"; spring length capacity: up to 15" uncompressed.
• Best for applications where internal clamps fit inside the coil turns.
• Not intended for extremely large commercial springs beyond listed limits.

What tools and techniques do I need to use it correctly?

Use a 1/2" drive ratchet or breaker bar to tighten the compressors evenly; alternate sides to keep the spring centered. Inspect jaws and threads before each use, and follow safe lifting and eye‑protection practices—never rely on the compressor as the only safeguard while working under a suspended vehicle.

• Drive size: 1/2" — use a torque‑rated ratchet or breaker bar.
• Tighten alternately on each compressor to maintain balance.
• Wear safety glasses and gloves; secure the vehicle on jack stands.
• Check jaws and threads for wear prior to each job.

Who is this for: The Acymner 14" Coil Spring Compressor set suits DIY mechanics, mobile technicians and professional workshops that perform strut and suspension servicing. If you regularly replace shocks, struts or coil springs and need a durable internal compressor with a 1/2" drive option and a 14" jaw capacity, this set provides the rugged build and predictable control required for safe, repeatable jobs.
