The “Dirt Dog”
The Dirt Dog truly, is a first of it’s kind. There are certain pull down rigs on the market that can send a dirt car through it’s travels, but the difference comes with how they send the rear end through the travels. Most rigs on the market have a system that hooks to the chassis or the rear end and uses the rig itself to “lift” the car up. The Dirt Dog uses a special push-up shock that replaces the LR shock and lifts the LR up without using the rig itself. Therefore not effecting the wheel loads at travel. The rig comes with 2 hydraulic pull cylinders and the WBP Push-up shock. This option can still be used to pull an asphalt car down using the two pull cylinders!
Air over hydraulic pumps
Works on any wheelbase and tread width
8″ travel front, 6″ travel rear, 8″ travel LR.
Use your scale pads or purchase new Wireless Proform scales for $800.
Roll off stands available for any height scale pad
Pull down rigs are the new gotta have, go fast tool. While pull down rigs are very useful, they are not an absolute necessity to go fast. We’ve produced a pull down rig that does the job without breaking the budget. The Dirt Dog allows you to quickly measure dynamic cross/camber/caster/wheelbase/tread width/Front and Rear geometry and check for binds in your shop or even at the track. Complete most of your setup work on the included roll off stands to speed up the process.
All that is needed is travel data for your particular setup and track and the PDR will give you accurate, affordable information.
The WBP Load Dog has the racer in mind. It has the best value on the market, utilizing simple hydraulics the Load Dog will travel your vehicle to any position desired. This is achieved by using 2 pull cylinders(1 on RF and one on the RR) and the LR Push-Up Shock. Scale stand boxes come with removable roll offs and all stands have adjustable leveling feet.
The Load Dog will tell you your vertical wheel loads at any position of your travel on the track. Ideally you would use a data acquisition system to travel your car exactly to the point it does on track. Travel indicators mounted on shocks or the car can be a secondary method to compare travel distances.
The Load Dog now has hangers built to ease the movement of the longitudinal bars when they are positioned outside of the scale stands. The roll offs also now have a quick lock system to allow easy removal when needed. Wheel chalks have also been added to the LR and LF boxes. Options are available for 1.875″, 2.5”, 3”, 4” scale pad heights. We have left this option open to the racer. We have been using 1800 lb scales and that would be OK for a dirt car or an asphalt car.
