Safe handling of all springs: Safe removal or installation of springs, shocks, struts and spacers with stable, balanced compression using the coil spring compressor tool. Safe locking design: The hook jaws combined with the precision thread of this user friendly screw spring compressor keep everything seated securely for added safety. Adjustable mounting: This spring compressor features an adjustable mounting that ensures parallel compression and protects against accidental release under high tension. Ideal for most vehicles: With its range of 11 and a capacity of 2200 pounds, this screw spring compressor works well for springs with a wire diameter range of 0.6 to 0.8, as found on most cars, pickups and other large vehicles. Use scenarios: - Replacing front coil springs on a typical passenger car or light pickup, with safe removal and installation of springs, shocks and spacers. - Servicing shocks or struts on SUVs and larger vehicles that require controlled, parallel compression to prevent kickback. - Working on suspension upgrades or repairs involving high-tension springs within the 0.6–0.8 wire diameter range for a wide range of vehicles.
