| My truck currently has a Holland low profile riser / slide bracket and is considered a 6.63" height.
I am getting ready to install a set of fiberglass rear ( fenders ( flat top ) over the tandems, and curious how much you guys had to increase the 5th wheel height.
I put my truck and dump trailer in its most severe ( turned/ twisted ) position to measure clearance and I presently have about 4 1/2" from tire to trailer frame.
I am thinking I need a good 2"-3" clearance under the fenders for tire clearance and another 4"-5" for trailer to fender clearance ?
Holland makes a 10.12" bracket so I am only gaining roughly 3 1/2" there and so would probably have to build and block up from frame from there.....does this sound correct ?
Buddy and I have installed a few fenders on customer trucks, but never quite this extreme and those trucks were pulling vans and flatbeds, and those customers dont see the severe angles coming out of fields like my scenario either.
So....what are your measurements from top of 5th wheel plate to frame do you guys have ? just wanting something to compare to.
THANKS IN ADVANCE.

Ainsworth, IA | We put plastic fenders on our w900. Gave them 1" clearance with the air out of the suspension. Used the 10" Holland riser and have plenty of room. We run hopper bottoms and get into some really tricky places. Haven't damaged a fender since the riser plate was installed. You could buy the riser and if you need more space, modify it. |

Sort of Central to North Central Iowa | I put Minimizer plastic half fenders on our truck. Thought I had plenty of clearance tire to fender clearance, but with the oscillation of the spring suspension, sometimes the wheels come up more than I realized. Only happens on very uneven ground, but often enough that it wore a hole in the fender. Once again, this is with a spring suspension. |

| Are you measuring the riser from where it sits on the slide to the middle of the pin? That's how holland measures them. Not from the frame to the pin like most people I have seen do it. Just making sure you are calculating the space properly. Good luck. |

| I contacted Holland direct, and my rep ( Angie Cariano ) said, and emailed, top of fifth wheel plate to top of frame. I dug out my Holland part reference guide and they showed the measurements 2 ways...
1.) top of 5th wheel plate to top of frame
2.) bottom of slide bracket / plate to top of slide bracket
My slider plate would be like 3/8" above the frame, probably more like 1/4", and it bolts to the side of the frame.
You are not alone in your measurement process, my buddy who is in truck service always measured them your way too ( instead of top of 5th wheel to top of frame ).
