Krazy House Customs Krazy House Customs is the evolution from Grizzly 4WD that has been around since the 80s serving northern NJs Offroad needs. Now located on busy Rt. 1 in Monmouth Junction NJ, Krazy House Customs is now serving all the Tri-State Truck and Automotive Aftermarket and Performance needs. We have been building Trucks and Cars of all makes and models for years, as this has been a hobby of ours for about 15 years. The owners run a successful security business and wanted to have their own shop to help others reach their goals with their Car or Truck. The owners have been building show trucks and cars as a hobby and were dealing with the Grizzly 4WD business for years, after taking over the business it was decided to expand it into a much larger and more service oriented shop. We now have 6 bays with a Hunter Alignment Rack and an AWD Eddy Current Mustang Dynamometer.
