Smooth out the ride and keep the rear end planted with the Monroe OESpectrum Rear Suspension Shock Absorber 37078, a light-truck shock designed to help restore your truck's original factory drivability, handling precision, and control while filtering out impact-related noise, vibration, and harshness. It installs in the rear position as a direct-fit replacement for the 1986-1994 Nissan D21, the 1998-2004 Nissan Frontier, and the 1995-2008 Nissan Pickup — see the Buyer's Guide tab for engine-level fitment.
- Exceptional handling: Full displaced valving is tuned specifically to each vehicle and adjusts to road extremes, while a larger bore delivers more efficient damping control for a consistent, smooth ride.
- Control and durability: A PTFE-banded piston provides consistent sealing between the piston and pressure tube for better control and increased durability.
- Improved ride: Nitrogen gas-charge helps maintain tire-to-road contact by reducing aeration and shock fade.
- Consistent ride: OE all-weather fluid contains special additives to assist with temperature extremes and help reduce oil breakdown, and a self-lubricating seal retains gas while reducing friction against the piston rod.
Twin Technology Active Control System isolates impact-related NVH under most driving conditions. Backed by Monroe's Limited Lifetime Warranty and Feel the Difference Guarantee.
