2nd gen sumo springs on 3rd gen

Will these (

$223 SSR-611-40 | SumoSprings Rear for Toyota Tacoma, silver, 500 lbs.

SSR-611-40) work on 3rd gen with 1 3/4" lift? 3rd gens have a different part # (

SSR-612-40) but are supposed to already be 1" shorter. The ends of one curve up but I can't imagine these slipping off without that due to the amount of pressure already on them with the ubolts.

 

SSR-611-40 is intended to be bolted to the frame upside down for 5-lugger spring-under-axle applications. If you attempt to mount it on the leaf pack in a spring-over-axle config, the threaded stud will interfere with the leaf spring center pin. It's also half the stiffness - 500 lb at 50% compression.



The 2nd gen 6-lugger P/N is SSR-610-40, rated for 1000 lb at 50% compression.

3rd gen P/N SSR-612-40 is rated for 1400 lb at 50% compression.

Seems to me either SSR-610-40 or SSR-612-40 can mechanically fit (the install guides use the same photos), so your choice depends on the expected cargo weight.
