The strength of the rescue rope you need depends on the vehicle or stuck object you want to rescue. For vehicles like ATVs, UTVs, and Snowmobiles, you need a breaking strength of up to 7,300lbs with a ½ diameter retrieval line. Users require a breaking strength of up to 16,000 lbs for small SUVs and Jeeps with a ¾ diameter retrieval line. 7/8 diameter retrieval lines with a breaking strength of up to 24,700 lbs. are an excellent choice for salvaging trucks.
