Truck Modifications



When it comes to truck modifications we can do it all.  Whether its our truck or a truck you own, we can make the modifications necessary to make it fit your application.  Below we go into detail on Wheelbase Lengthening & Shortening, Auxiliary Axles and Power Take Offs.  All modifications are done in house by our experienced service department.  


Wheelbase Lengthening & Shortening

   Before a truck's wheelbase is ever changed you have to know exactly what length it needs to be.  We have a spreadsheet program from the NTEA that will tell us what each axle will carry at different wheelbase lengths before we start.  This way we can maximize a trucks legal payload and explore the possible need and benefit of extra axles.

   We use only the highest quality materials and components.  Our drivelines and jackshafts are provided by Inland Truck Parts.  Our frame steel is provided by T & W Steel and is broke to match existing truck frames.  You can visit Inland's web site at

   Throughout the process of changing a truck's wheelbase, safety and reliability is a major concern.  Once we're done the truck will be at least as strong as before and in most cases stronger.  Don't let just any shop perform this type of modification to your truck. The liability concerns are too great. 


Auxiliary Axles
   In today's competitive market, payload plays a major factor when setting up a new unit.  State, Local and Federal laws concerning truck weights are being enforced more vigorously than ever.  Also, safety plays a major concern in which you don't want an axle carrying way more than it was originally designed for. 

   This is where an Auxiliary Axle can help.  Once again we use the spreadsheet mentioned and shown above to find out how you will benefit from another axle and where the best placement would be in your particular situation.

   When it comes to the axle itself, we are proud dealers of the Ridewell make of suspensions.  Ridewell Corp. of Springfield, Mo has a large family of different suspensions to fit any application.  Their workmanship and attention to quality has proven them to be among the best in their field.


     Two of their models that we use the most are the RCA-235 and the RSS-236 


   The RCA-235 is a compact, lightweight suspension for use in pusher or trailing applications.  It features air ride and also air lift.  It has a capacity rating of 22,000 lbs. standard which is more than enough for most applications.

   The RSS-236 is a self-steering suspension for use in either pusher or trailing applications.  It also features air ride and air lift. It has a capacity rating of 13,000 - 20,000 lbs.  Available with automatic raise when you put your truck in reverse or self-steering in reverse.

   To the right is the finished product.  The truck was then equipped with a 28' Warren Feed Body and has a legal payload of approx. 20 tons.  The body features included:  radio remote controls, bag shelf cover, 8 compartments, one piece top door and a 32' discharge auger.

Power Take Offs


   In selecting a Power Take Off (PTO) many different factors should be addressed.

   First and foremost is the brand.  We use the Chelsea make of PTO's.  There quality and longevity over the years has proven them to be among the best on the market today.

   Second is how your PTO should be equipped.  In most applications these days hydraulic pumps can be bolted directly to the PTO which eliminates the need of a drive shaft and decreases maintenance.  In this case the PTO would need to have a direct mount flange to accommodate the pump mounting.  Also on air brake trucks it is an advantage to use an air shifter to engage the PTO instead of a cable which is prone to getting stiff over time.

   Third and most importantly is the speed of the PTO.  PTOs come in a variety of different speeds and are measured as a percentage of the engine's RPM.  Correct speed ensures that the hydraulic pump is producing the correct amount of flow for an application's system.  Too fast and the system will overheat causing premature wearing of motors, pump, seals, etc.  Too slow and the system will not perform up to its potential.  Each type of body or application has its own requirements for gallons/min. flow and certainly needs to be addressed before a PTO is selected.  

   Feed trucks are stationary while unloading and only have to have enough horsepower to run the pump.  For this reason it is preferred to have a PTO speed that allows the truck to run at lower RPMs reducing engine wear and fuel consumption.  Spreader trucks on the other hand run at higher engine RPMs which requires a slower PTO in comparison.
