Curt C31088 Hitch Measurements

Updated 04/01/2026 | Published 03/27/2026

Question:

Why do you have ZERO dimensions for these hitches? Am I doing something wrong? Are they kept from people for a reason? I dont want anyone basing decisions on yr make or model. How to I get the dimensions of the C31088 or similar hitches. I need to know the overall width from end of the side plates to the crossbar, distance between the plates O.D. THKNES of the plates, top 2 bttm width of the plates, length of the plates, size of the bent tabs, distance between bent tabs on each plate. Lenth of the 2inch recvr snout. Please send complete Dims, thx

Hey Chris, our custom-fit hitches are fit-guided so that people can select a hitch based on what vehicle they have, not by measuring to confirm fit the hard way. The Curt Front Mount Trailer Hitch Receiver - Custom Fit - 2" # C31088 fits
2019 - 2021 GMC Sierra 1500
2022 - 2022 GMC Sierra 1500 Limited
2019 - 2021 Chevrolet Silverado 1500
2022 - 2022 Chevrolet Silverado 1500 LTD

That said, I went out to the warehouse to measure for you. It's easier to illustrate by attaching pics, so that's what I've done for you.

Let me know if this helps figure out fitment.

I need a hitch 32 in wide with flat 4" square ends to fit in the C frame of a 99' F350 Chassis service truck needs a 8" -10" long receiver snout or 4" an extension. Class 4 or 8000lb gross tow capacity. I'm an engineer I build airplanes I really don't care what anybody's policy is if I don't have weights and dims then I can't work I can't design I can't build no one can this is ludicrous to say I gotta kno the year of yer freaking truck.... it's a 2037 I don't give a crap this is like pulling teeth to get Dimensions out of you guys

@ChrisH Yeah unfortunately we don't have a database that has all these dimensions for the thousands of hitches we have, nor does the manufacturer even provide those. Best bet is to use the fitguide for the 99 Ford F350 cab and chassis model, since it sounds like that's what you have. You could go with the custom fit Curt 2 class 4 # C14048 or the Curt 2-1/2" Class 5 # C15845. Otherwise, you can fabricate your own if you want to by using these receiver bars as a starting point: - # E-11 2" receiver bar 12" long - # E-9 2" receiver bar 6" long
