Aggressive Hydraulics periodically sends out targeted mailings (e-mails/post cards) to specific industries and potential resellers. One of those potential resellers was MIS. MIS received their post card, and happened to be seeking a new source to provide quality replacement cylinders at the right price, and within a specific lead time.

MIS contacted Aggressive’s Paul Johnson to learn more. Paul explained how Aggressive has one of the most experienced design & engineering groups in the industry, and how Aggressive specializes in high-end custom builds. MIS liked what they heard, so they decided to send up a sample cylinder to quote and blue print.

The price and lead time was what they needed and the first order was placed. MIS was very pleased with the final product and have done a total of three different cylinders with Aggressive to date. MIS then became an authorized reseller and have had many repeat orders of these cylinders.

Aggressive also met MIS’s requirements to specially package the cylinders so they can take it right from the shelf and ship it.
