Orion Motor Tech MacPherson Strut Spring Compressor Set 10.5" Range — Hardened Steel, 1/2" Drive

OMT's MacPherson strut spring compressor set is a durable, portable two-piece tool kit designed to safely compress coil springs up to a 10.5" jaw opening for routine suspension work.

When servicing MacPherson struts, having a reliable spring compressor makes the job faster and safer. This Orion Motor Tech (OMT) kit pairs two matched compressors with a blow-molded case, engineered threading, and hardened steel construction so you can move springs between struts or replace mounts without guesswork. The tools work with common 1/2" square drives or 13/16" hex sockets and are sized for most small- and medium-sized vehicles.

How does this compressor set make strut disassembly easier?

The set uses precision-cut threaded rods and wide end pieces to grip coil springs securely while you reduce spring tension. Smooth shaft travel minimizes binding, and the included locking pins hold your progress so you can focus on reassembly instead of constant adjustments.

• 10.5" maximum jaw opening fits most small/medium car springs
• Wide end pieces increase contact area and reduce slippage
• Locking pins add an extra layer of security during work
• Compatible with manual ratchets or power tools via 1/2" drive

What materials and finishes prevent wear and corrosion?

OMT built these compressors from heat-treated 40Cr steel for high strength under repeated compression cycles. Threaded rods receive a black oxide finish to resist rust, while the galvanized end pieces offer additional corrosion protection in exposed garage environments.

• Heat-treated 40Cr steel construction for durability
• Black oxide on threads to reduce corrosion and galling
• Galvanized contact pieces for long-term wear resistance
• Designed to withstand frequent professional and DIY use

Can I use power tools with these spring compressors?

Yes — the main shafts accept a 1/2" square drive or a 13/16" hex socket, so you can use a breaker bar, ratchet, or compatible power tool for faster operation. The smooth, precision threading ensures predictable movement when you add torque, but always follow safe practices and tighten in small increments.

• 1/2" square drive and 13/16" hex socket compatibility
• Precision threading for controlled, even compression
• Use short, steady increments with power tools to maintain safety
• Locking pins recommended for additional peace of mind

Who is this for? Mechanics, home DIYers, and fleet technicians who service MacPherson strut suspensions will find this OMT compressor set practical and reliable. It’s sized for most compact and mid-size cars, packaged in a compact blue blow-molded case for neat storage and easy transport — a sensible addition to any garage or shop that performs routine strut and spring maintenance.
