My Dually Had Been Stolen Twice, Several Of My Customers Had Been The Victim Of Their Suburban And Dually Thefts. I Have Since Then Installed A Brake Locking Device On My Vehicles. The Third Time They Tried To Steal It, They Pushed On The Throttle So Hard, That It Twisted The Input Shaft On The Trans. I Still Have It. It Fits In The Line Like A Line Lock. You Flip A Switch, Apply The Brakes And They Stay Locked. Or, You Can Leave The Switch On, (it Does Not Draw 12v Power Until You Apply The Brake, And, Only For A Moment) And, If Anyone Tries To Drive It, The First Time They Apply The Brake, They Lock And Stay Locked. Better Than An Alarm, And You Can Leave The Keys In The Car. We Sell Them.
