A shock absorber assembly kit bundles the shock absorber with wear items — dust boot and dust shield — that protect the shaft and seals from road debris and contamination. Buying them together ensures correct fitment of the protective components and saves the hassle of sourcing them separately. These PRT kits include both the boot and shield; select part numbers also include mounting hardware.

PRT shocks use dual-tube, gas-charged construction comparable to KYB Excel-G and Monroe OESpectrum units at the same performance tier. PRT sources from Brazil under ISO-certified manufacturing and is considered OE-comparable in valving and build quality. They are a solid value alternative when you want better-than-economy performance without stepping up to Bilstein pricing.

Common signs include excessive body bounce (more than one or two oscillations after pushing down on the rear bumper), cupped or uneven tire wear, nose-dive under braking, vague steering, or visible oil leakage on the shock body. At 50,000–70,000 miles, shocks are worth inspecting even without obvious symptoms, especially if you notice a gradual change in ride quality.

Yes — always replace rear shocks in pairs. Installing one new shock alongside a worn unit creates uneven damping side-to-side, which can cause handling imbalance, unpredictable cornering behavior, and uneven tire wear. Matching both sides ensures consistent rebound control and restores the vehicle's designed suspension geometry.
