1100 rear shock question

[tuna boy]

Did the 1100"s shocks always come with internal helper springs? I have a factory manual and don't see springs. I have a 1980 standard. I think that the shocks have the progressive springs but not sure. If I bleed the air off the shocks and there are no springs I would guess that I could easily bottom the rear eng. Thanks, Tuna

Yes they all have springs.
Which case the air is actually the helper.
