Heeeere's...Laid-Back's "Jambulance" and The ADJUSTER

Check out what our good friends at Laid-Back are bringing back to life with a little help from the Adjuster! Can't wait to see it on Power Tour!

The Laid-Back Jambulance is alive! We found this 71 suburban ambulance and could not resist the urge to bring this thing back to life. Corky a.k.a. Doc shoehorned in a 5.9 Diesel Cummins and we added the Attitude Adjuster from Attitude Performance products to make it scream. Kicker hooked us up with 800 watts of love to make it jam. Now we need to make it roll. Power Tour 2017 here we come!
