These are about the only legal swivel bases for a Chev van these days.
The last van I converted was in 1979 and van accessories were everywhere.
Fast forward to 2026 and that's just not the case anymore.
These bases are great BUT. THE REARWARD OF THE 6 BUTTON HEAD 3/8" SOCKET SCREWS ARE TOO LONG!
No big deal if you know that ahead of the installation. Those back screws take the majority of forces in the event of a front end collision. How many people are driving around right now that never got around to filling those holes?
To add insult to injury, this retired heavy industrial mechanical tradesman managed to crush his middle finger tip with a 3/8" punched hole through the skin while **** around with this.
No mind altering drugs or alcohol were involved. Just working alone, tired and pissed off. For about $1000 Canadian which includes the Trump factor I figure someone on the design team might want to install one of these sometime.
Can't beet the quality or PRICE!!
No instructions. The customer installs on the website are for designs that probably don't exist anymore. The amount of rise in the seat means someone with short legs will have their feet dangling in the air. I'll probably uninstall it and try to sell it then look around for a swivel with less rise. My speculation would be that they went from dedicated designs for every camper van brand to something more generic that fits multiple vehicles.
Infinitely better than the discountvantruck.com seat swivel (an unbelievable piece of garbage).
Like others have noted, this swivel was near impossible to swivel. So had to crack the locktite on each bolt and loosen the mechanism a bit. Hopefully that doesn't progress into some issue.
Other than that, it fit perfectly onto my 2025 GMC Savana passenger seat.
Easy installation
