The only tool here that stores energy while you work · review
The set that publishes a rated load and describes its safety claws: 1200 kg (2645.5 lb), drop-forged interlocking claws and a reinforced spindle.
The last word Load rating, claw design and steel all published. On this family, that is the whole argument.
A two-piece MacPherson spring compressor set rated at 1200 kg (2645.5 lb), with drop-forged interlocking safety claws, a jaw capacity of roughly 70 to 270 mm (2.76 to 10.6 in) and a reinforced spindle, in heat-treated 45# carbon steel.
Every failure in this family is a claw leaving a coil. Interlocking, drop-forged claws are designed to capture rather than to rest, and the difference is what the extra money buys.
1200 kg (2645.5 lb), stated. It is the figure the cheaper sets omit, and it is what lets you check the tool against the job rather than hoping.
The manufacturer’s. Even winding, by hand, both sides, claws fully seated, nobody in line with the spring.
On sale at around $57 on the American Amazon store at the time of checking.

Claws that close around the coil and lock, rather than hooking over it. It is the feature that stops a clamp jumping off under load, and it is the one worth paying for in this family.
It is a stated capacity for the tool. Whether it suits your spring depends on the spring, and the vehicle manufacturer’s documentation is where that is established.

2 pieces · 370 mm (14.6 in) span · 4 claws · CR-V steel stated
A pair of external clamps with a 370 mm (14.6 in) span — the entry point to a job that stores enough energy to injure, and the point at which the manual matters most.
Best for: A single suspension job, done to the manufacturer’s procedure and no faster.
Universal MacPherson set · for removal and refitting of struts · stated for conical and cylindrical springs
A universal MacPherson set stated to suit both conical and cylindrical springs — which is the shape question a clamp has to answer.
Best for: A strut with a conical spring, where clamp geometry is the constraint.
