The Dennis SS series is a fire engine built by Dennis, it was produced from early 1980s until 1990s.

The Dennis SS was almost identical with the Dennis RS, incorporating the same cab design, engine/transmission and axles, except the SS had a tilting cab which made maintenance and overhaul much easier. It could be fitted with a variety of bodies by Dennis/JDC, Carmichael, Fulton Wylie, etc.

Even though the cab design of the SS dates from 1978, they are seen to this day in fire brigades all over the world, with many still in front-line use to this day. In the later years the SS series appliances were dogged with door corrosion, aptly known as "Dennis Disease" as almost every single SS appliance suffered from rotten cab doors at some stage in their lives.
