CHIEFWAHO Posted May 22, 2018 Report Share Posted May 22, 2018 I had purchased new rear air bags for my TrailerSaver hitch awhile back. Decided it was time to get them on and while at it add a 3rd air bag. After some research I believe I figured out what air bag to use . Went ahead and removed the swing arm. 2 holes drilled, down approx 3" from top edge and centered to opening. My homemade bracket. Test fit and mark new hole location in the base plate. New rear bags ready to go in. New holes for bracket mounting. Drilled and tapped for 3/8" bolts. Brack Bracket sandblasted and painted with new 3rd air bag mounted. Finished product. I'm in about $120 for the 3rd air bag. 1999 Volvo VNL610, Cummins M11 - 350/400 HP, 10 speed Rockwell - 'CHIEF' Custom flatbed with TrailerSaver air hitch. 3 cyl 8000 watt Kubota diesel generator.

Alie&Jim's Carrilite Posted May 22, 2018 Report Share Posted May 22, 2018 Nice! If you ever need to dampen the recoil from the bags, disconnect the air from '3rd" bag and plug the line. It acts like a return spring/snubber for those 14% pin weight trailers.

My new Trailersaver came with a third air bag. My trailer pin weight is fairly light. I will have to recall the weight sheet. So I would disconnect the third bag and let the air run in/out and thereby making it act like a rebound shock absorber. Interesting idea. Do I need to put some kind of filter on it to keep the dirt out?

RandyA Posted May 25, 2018 Report Share Posted May 25, 2018 Very nice. Appreciate the detail and bag part number. Question..... I see a shock absorber. The hitch I just installed is a TSLB and there is no shock. Was that added to the TSLB2H and not mine? Seems to me a shock would be beneficial. Stop any basketball type bounce. Thinking the 3rd airbag as a damper could do the same work as a shock. I hooked up today for the first time and inflated the 2 bags so the white line was at the top of the lower frame. Air pressure in the bags was 60 psi. Hensley manual says not to exceed 50 psi. Any feedback? I may need a third airbag. Do not know my exact pin weight but figure 3,500 to 4,000 with 18K to 19K at 22%. It would be nice to have your project in the Resource Guide.

Randy, some of the Trailersavers had 1 shock in the middle like this one, some had 2 mounted on the outside of the hitch. I pulled with and without the shock on ours and really can't tell the difference.

But found where these show to be the same bag. GoodYear 1B 8-1 579-913-532 is the same as the Air Lift 58124. And the Air Lift is a Single Industrial Air Suspension Spring bag. That Air Lift uses. Also my hitch has the outside shocks, one each side. Pete Link to comment Share on other sites More sharing options...

Jack Mayer Posted May 28, 2018 Report Share Posted May 28, 2018 When I converted my TS into a three bag system the shock was removed. I had a single shock - the TS was 2002 vintage - and I bought it new. Later model TS frames had the holes already there for the third bag, even if the bag was not present. But on the older frames, you have to drill the holes, as shown above. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

leavingsoon Posted July 22, 2018 Report Share Posted July 22, 2018 Thanks to Alie & Jim I found this conversation. I am wanting to add the 3rd airbag to my TSLB hitch but was shocked when I saw the cost from TS. Was hoping to find it elsewhere but I seem to be learning that the kit is only sold thru TS???
