Off-road shocks have a bigger diameter than the standard ones. Their replacement necessitates fitting new springs. They are equipped with an additional gas tank. Steering stabilizers are very useful, especially for driving off the road, when you're going over uneven surfaces at a high speed. They prevent the steering wheel from jerking, i.e. they dampen sharp turns in such a way as to prevent you from losing your grip on the wheel. Steering stabilizers are a standard feature on some off-road cars.
