Question:
Can I get the slot dimensions on the rails for 16027 adapter? I would like to see if my hijacker hitch will fit your rails. Adapter would be for a 2021 GMC 2500

Expert Reply:
The Adapter Rails # C88KR (16027) will fit the OEM prep in your 2021 GMC Sierra 2500 and provide you with industry standard mounting points. As long as your Hijacker hitch uses industry standard rails, then it will work with the # C88KR adapter.
I have also included a diagram that shows the spacing of the slots in the Adapter Rails # C88KR.
