Seat strut on the RT

[Mazo EMS2]

I replaced the stock seat with an Ultimate with backrest, and now the strut won't hold the seat up. Does anyone know a part number for a stronger strut? Blue Knight Mike, what numbers can I cross reference for McMaster Carr?

I have the one on this thread on my Ultimate seat and works great!

Hi, I sent you a couple of PM's ….. McMaster Carr ( listed as a gas spring ) # 4138T56 …. that's for the size of the part …. you need to pick how much FORCE you need …. Mike

How much force would it be for the regular RT seat???

I just went and checked that for my OEM RT seat strut ( now off the bike ) … pressure needed started at 22 lbs and was 28 lbs fully compressed …. hope this answers your Question ( see my post #3 for the part number you need - they have 30 & 40 lb struts )…… Mike
