412 HEAVY DUTY REAR SHOCK ABSORBERS FOR HARLEY-DAVIDSON IN BLACK & CHROME
The Progressive Suspension 412 shock absorbers are among the most popular suspension upgrades for Harley-Davidson models. The proven and robust design offers a significant improvement in ride comfort, stability, and control compared to the stock suspension. Thanks to the five-way adjustable spring preload, the suspension can be quickly and easily adjusted to the rider, load, and riding style.
DETAILS
Specially developed for Harley-Davidson models
Proven 412 suspension system
Improved ride comfort and greater ride stability
Robust and durable construction
5-way adjustable spring preload
Easy adjustment to rider weight and load
Ideal for solo and passenger use
Cost-effective suspension upgrade
Made in the USA
On Sportster models from 1986–2015, depending on the version, an adjustment or spacing of the chain or belt guard may be required.
Longer shock absorbers can make the steering behavior more agile.
Shorter shock absorbers can make the steering behavior slightly calmer.
Before installing shock absorbers of a different length, it should be checked whether there is sufficient clearance to the swingarm, tire, exhaust, and belt guard.
For motorcycles with a high continuous load, heavy-duty versions are recommended.
COMPATIBILITY
Suitable for many Harley-Davidson models.
Please check the vehicle compatibility before purchase.
