The H&R 50856 is a set of Sport Springs for the 2007–2010 Dodge Nitro 2WD. Owners on user forums describe the steel as 54SiCr6 spring steel, and the manufacturer's technical notes say its springs are progressive where the application allows. Compared with stock springs, a lowered center of gravity should reduce body roll in corners and tighten up the look of the fender gap. The progressive rate is meant to keep daily ride quality reasonable while firming up under hard cornering. Forum owners also warn that stock-length shocks can run near full compression once a Nitro is lowered, so plan on shorter or upgraded shocks such as Bilstein units if you want the full benefit of the springs.
Buyers searching for 2007-2010 Dodge Nitro 2WD lowering springs, H&R sport springs 50856, and Nitro coil spring lowering kit should confirm their drivetrain and suspension codes on the build sheet before ordering. The manufacturer says front and rear springs are marked (F) or VA for the front and (R) or HA for the rear, and recommends measuring ride height before and after installation from the center of the axle to the fender lip. Per the manufacturer, alignment should be checked after any ride height change, following the factory service manual.
Owners on user forums recommend checking the suspension codes on your build sheet before ordering, since the Nitro's suspension varies by configuration.
The manufacturer advises checking alignment after any ride height modification and following the factory service manual to get as close to factory specification as possible.
Owners on user forums report that stock-length shocks operate close to full compression after lowering, and many recommend shorter shocks or upgraded units such as Bilstein.
The manufacturer marks front springs with VA or (F) and rear springs with HA or (R).
The manufacturer recommends measuring ride height before and after installation from the center of the axle to the lip of the fender, using the technical sheet included with the set.
Plan on a floor jack, jack stands, and a full set of hand tools. Rear springs are the more involved job: owners on user forums report that the rear axle has to be lowered with a jack under the differential so the springs come free. Before that, the rear shocks, sway bar, differential breather hose, and brake line bracket need to be disconnected, and owners warn to take care not to tear the brake hose or vent hose. Front work centers on the coil-over shock assembly rather than a strut, so budget extra time there. Once the install is done, get a four-wheel alignment, and expect the ride to feel firmer until the new springs settle.
