Features

150 PSI nitrogen gas-charged pressure actively suppresses fluid aeration and damping fade, delivering consistent rear shock performance under the increased suspension travel of a 2-4 in. lifted classic GM truck or SUV
True velocity-sensitive valving continuously adjusts damping resistance in real time based on terrain speed and suspension input, providing stable and controlled rear-end behavior on and off-road
Twin-tube construction with multi-stage valving provides a stable secondary fluid chamber for consistent compression and rebound throughout the full 11.03 in. stroke
Oversized bonded iron piston head delivers precise fluid displacement and smooth damping force across the extended stroke range required by 2-4 in. lifted applications
5/8 in. diameter hardened, double-chrome piston rod resists corrosion, bending, and surface wear under decades of use on classic K-Series and V-Series platforms
Leak-proof seal and orifice disk design prevents fluid bypass and supports extended service life even on older vintage 4WD platforms
Red polyurethane bushing at the lower Eyelet/Sleeve mount provides improved vibration isolation and far greater durability than aging OE rubber bushings on these platforms
Upper Eyelet mount provides a clean, direct bolt-on installation using factory shock hardware - no modification required
Red protective boot included to shield the piston rod from mud, rocks, and trail debris
Internal rebound bumper prevents metal-to-metal contact at full droop during heavy rear suspension articulation
Shock must mount body-down - mandatory installation orientation for correct function and longevity
Limited Lifetime Warranty backed by Skyjacker's SkyArmor Plus supplemental warranty program

Product Description

The Skyjacker N8053 is a Nitro 8000 Series twin-tube, 150 PSI nitrogen gas-charged rear shock absorber engineered for 2 to 4 inches of rear lift on classic full-size Chevrolet and GMC K-Series and V-Series 4WD trucks and SUVs spanning model years 1973 through 1991. It covers the Chevrolet K10, K20, K30, K5 Blazer, Blazer (1987-1991), and their Suburban variants, along with the GMC Jimmy, K1500, K2500, K3500, V1500, V2500, V3500, and their Suburban counterparts. When a truck in this era is lifted 2-4 inches, the factory rear shocks are left operating outside their designed travel range - too short to function correctly at the new ride height, leading to harsh and uncontrolled rear suspension behavior. The N8053 is purpose-built to restore proper damping control with an extended length of approximately 27.07 in. and a stroke of over 11 in., sized specifically for lifted GMT400/C/K-platform suspension geometry.

The nitrogen gas charge suppresses fluid aeration and fade during sustained hard use, while the velocity-sensitive valving adapts in real time to terrain speed and suspension input. The result is a stable, composed rear end whether you're running trails, hauling payload, or driving on-road with a lifted classic truck. The oversized bonded iron piston and 5/8 in. double-chrome piston rod are built for durability across the long service lives these trucks are known for, and the Eyelet upper / Eyelet-Sleeve lower mount configuration allows bolt-on installation using factory shock hardware.

This shock is designed strictly for 4WD applications with 2-4 in. of rear lift. It will not function correctly at stock ride height or for 2WD configurations. A slight spec variance exists between sources: the Skyjacker manufacturer source lists 27.07 in. extended / 15.94 in. collapsed, while ShockSurplus lists 27.19 / 16.16 - the Skyjacker figures are used as the primary reference. Sold individually; order two for a complete rear replacement. Fitment is confirmed through 1991; no 1992 or later applications are listed for this part number.
