Signs include excessive bouncing after bumps, nose-diving when braking, uneven tire wear, fluid leaks on the shock body, or a rough ride. Most manufacturers recommend inspection every 50,000 miles.

Yes, always replace shocks in pairs (both fronts or both rears). Mismatched shocks cause uneven handling and accelerate wear on the new shock. This kit includes a matched set of 2.

Shocks typically don't affect alignment since they don't change suspension geometry. However, if your vehicle had worn shocks for a long time, getting an alignment check after replacement is good practice.

Basic tools include a socket set, wrenches, jack and jack stands, and penetrating lubricant. No spring compressor is needed for stand-alone shocks. Installation typically takes 1-2 hours per pair.
