Seats Plungers

4 products

Seats Plungers for Harley-Davidson are the spring-loaded mechanisms that give traditional solo seats their signature cushioned ride. Stocked by Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, our collection features seats plungers from Samwel and MCS. These components suit a broad range of classic models, including 45 SV machines from 1929–1973, Big Twin frames from 1936 to early 1981, and all Harley-Davidson Flathead and OHV models equipped with T-bar mounted solo seats from 1929 to early 1981. Plungers wear over time, losing their spring tension and allowing the seat to bottom out on bumps, so replacement restores the smooth, controlled ride your classic machine was designed to deliver. Each plunger is manufactured to original specifications, ensuring correct spring rate and travel. Whether your build is a faithful restoration or a bobber with a sprung solo saddle, quality plungers make a genuine difference to rider comfort on your Harley-Davidson. Browse the full range below.
