Regular vehicle maintenance not only protects your investment but also enhances your safety on the road. Coil springs are the helical metal springs that support your vehicle's weight and absorb impacts from road irregularities. These components compress when you hit bumps and extend back to their original height after the force passes. Properly functioning coil springs maintain ride height and provide the foundation for smooth suspension operation. We stock genuine Nissan coil springs manufactured to exact specifications for your vehicle's weight and suspension design.

How Coil Springs Support Your Vehicle

Coil springs bear the entire weight of your vehicle while allowing suspension components to move up and down independently. The springs compress during impacts to cushion passengers from jolts and vibrations. Spring rate determines how much force is required to compress the spring a specific distance. Your Rogue and Sentra both use coil springs with specific rates matched to vehicle weight distribution and intended ride characteristics. These components work directly with shocks and struts to control suspension movement and prevent excessive bouncing. Genuine Nissan coil springs use high-grade steel that resists fatigue and maintains consistent spring rates over extended use.

Why Coil Springs Weaken Over Time

Coil springs deteriorate from metal fatigue caused by millions of compression cycles over years of driving. Corrosion from road salt weakens the metal structure and creates stress points that lead to breakage. Overloading the vehicle with excessive weight permanently compresses springs and reduces ride height. Temperature extremes cause metal expansion and contraction that contributes to fatigue. Aftermarket springs often use cheaper steel alloys that sag quickly and may have incorrect spring rates. Generic replacement springs frequently don't match factory specifications for wire diameter and coil count.

When Coil Springs Need Replacement

Replace coil springs when your vehicle sits noticeably lower than normal ride height. Sagging on one corner indicates a weakened or broken spring on that wheel. If you hear clunking noises over bumps or experience excessive bouncing, spring inspection is necessary. Visible cracks, breaks, or corrosion on spring coils require immediate replacement for safety. Most springs should be inspected around 80,000 miles for signs of wear or sagging. You can trust CMA's Colonial Nissan to always have the parts you need at a great price.
