1) Adjustable mounting for parallel compression and protection against accidental release under high tension. 2) Safe handling of all springs: securely remove or install springs, shock absorbers and spacers with stable, balanced pressure generated by the spring compression tool. 3) Ideal for most vehicles: 11-inch reach and 2000 kg capacity; designed for springs with wire diameters of 1.5 cm to 2 cm, as found on most cars, pickup trucks and other large vehicles. 4) Safe locking design: the hook jaws engage with precise alignment to keep everything in place during use. Use scenarios: - Replacing coil springs on a midsize car or SUV, where controlled compression is required. - Removing or installing springs, shocks and spacers during suspension maintenance on pickup trucks. - Servicing coil springs on larger vehicles, including heavy-duty trucks and lead vehicles, where high tension must be managed safely.
