Rear hatch / Trunk lift supports - what is OEM strength / force?

[vanis13]

What is the OEM force/strength specification for the rear lift supports?

I'm working on a write up for supports options for a rack on the rear hatch and this sachs detail has it at 67 lbs - Passenger Side Liftgate Lift Support (SG301009) by Sachs®. Body Connection: Ball Socket. Shaft Connection: Eyelet. Compressed Length: 12-3/8". Extended Length: 20-1/8". Travel Length: 7-3/4". Capacity: 67.45 Lbs. more details on - https://www.carid.com/sachs/passenger-side-liftgate-lift-support-mpn-sg301009.html

GoWesty shays "the ideal" strength but doesn't specify https://www.gowesty.com/product/gas-struts-for-lift-assist/23475/rear-hatch-strut-vanagon-?v=

The Lift Support Depot shows 133, 139, 140 lbs for stock application - https://www.liftsupportsdepot.com/year-model-searc...R%203-DOOR

Gary lee indicates different strengths for the two sides, but no force numbers

The vanagon parts book specifies a different hatch strut for each side of the door.
Left side 251-829-331B lower strength
Right side 251-829-332 higher strength

If you have a rack, bike rack or gas/spare tire rack on the hatch get these shocks from McMaster-Carr. Push the button watch the hatch go up!

I removed a Stabilus from my van that was 300 N (67 lb) but I don't know if it was oem or a replacement. 250 lb struts held up the hatch with two mtn bikes on a Fiamma rack.

EDIT: Ha! The Stabilus shock has a url printed on it so it's clearly a replacement. doh.


Close-op of specs...

When I bought mine from Bus Depot in late 2018, they were offering 3 versions. I went with the middle version, it's def. got more lift than stock but not anything in a heavy lift like you would need with a bike rack or other rear hatch mounted item.
Hatch stays easy even in Winter when the shocks are really cold, so that's a nice bonus since it's a real pain when lift shocks are chilled and don't want to perform like normal in warmer weather.
