54000325Aftermarket suspension kits & shocks the supplier lists against the Low Rider S. Genuine Harley-Davidson is listed above, not here.
Front fork cartridges, a rear shock and reservoir mounting hardware perform different jobs. Start with the end of the motorcycle you want to change, then match the year, fork design and existing adjustment equipment.
This all-years selection brings earlier and later Softail applications together. The shock in the film is 54000384 for the listed 2025-on applications; it does not make that part suitable for an earlier bike.
The current catalogue separates 54000384 for 2025-on Softails from 54000325 for 2018–2024 Softails. Both descriptions specify tool-free preload, compression and rebound adjustment, a 46 mm piston and serviceability through Öhlins. Preload accounts for rider, passenger and luggage weight; damping adjustments then tune the response. Choose by the exact application before comparing the shared features.
Installation kit 54000321 is listed for 2018–2024 Softails without factory external remote preload adjustment. The 54000325 requirements call for it when the bike lacks the preload-adjuster side cover. It supplies the installation solution for that condition; it is not a second shock or an automatic requirement for every year.
Kit 45400355 is for the specified inverted forks; 45400356 is for conventional forks. Both include left and right cartridges, springs and oil, with compression adjustment on the left and rebound on the right. Installation tools are separate, and Harley-Davidson recommends dealer installation because specialist tools are required. A cartridge kit changes the internals of the existing fork; it is not a complete replacement fork assembly.
The Screamin’ Eagle / Öhlins rear suspension, part 54000384, is a monotube coilover shock with a separate reservoir. Harley-Davidson presents it as a handling and ride-quality upgrade developed with Öhlins for the more demanding Softail rider. Its exposed reservoir and adjusters also give the installation a distinctive appearance. The useful difference is that spring preload, compression damping and rebound damping can each be adjusted, rather than treating every change in load or riding preference as the same setting.
Preload sets the suspension’s sag to suit the weight of the rider, passenger and luggage, using an external adjuster. Compression damping is adjusted at the remote reservoir; rebound damping is adjusted at the bottom of the shock body. The product listing confirms that all three adjustments are tool-free. This gives you separate ways to set the loaded position and fine-tune the shock’s response. The film explains their roles and locations, but supplies no sag target, click settings or load limit for your motorcycle.
Inside are a 46 mm piston and precision CNC-machined, hard-anodised components. H-D describes the high-pressure nitrogen charge as helping the shock resist heat-related damping fade, with a low-friction seal-head design for smooth operation. The exact listing also identifies the low-friction shaft/seal-head arrangement. These are the manufacturer’s construction and performance claims, not a promise that damping can never fade or a measured comparison with your original shock.
H-D states that this unit is fully serviceable and repairable through Öhlins, giving it a maintenance route beyond replacement of the complete shock. That statement does not specify free repairs or a warranty term. The exact product record is for 2025-on Softail models; the film’s broader closing reference to 2025-on Harley-Davidsons should not be read as fitment for every family. Use the matching product below to confirm the motorcycle and installation details.
