Fitment Notes

• Fits the rear shock position only; all supported applications are 4WD solid-rear-axle configurations - not designed for 2WD vehicles
• Sold individually - purchase two (2) for a complete rear axle replacement
• Stock/factory height shock; the Eyelet upper and Eyelet/Sleeve lower mount directly replaces the factory rear shock mounting hardware throughout the 1973-1991 squarebody platform
• The H7053 is the direct rear companion to the Skyjacker H7051 front shock - the two are designed as a matched set for the full squarebody 4WD platform and are sold together by Skyjacker as complete front/rear shock upgrade pairs for 1973-1991 Chevrolet Blazer, Suburban, and GMC Jimmy 4WD applications
• The Chevrolet K-series designation (K10/K20/K30/K5 Blazer) was used through 1987; the V-series designation (V10/V20/V30 → V1500/V2500) succeeded it from 1987-1991 on the same platform with the same rear shock geometry - the H7053 covers both naming conventions
• GMC used K15/K25/K35 designations through 1978, then K1500/K2500/K3500 from 1979 onward on the same platform; both are served by this shock
• The 1987 model year includes both old (K-series) and new (V-series) designations on the same platform - both are supported
• Factory mounting hardware is reused; all necessary washers, bushings, and nuts are included

Features

• True velocity-sensitive hydraulic valving adapts rear damping resistance to actual suspension speed in real time - providing compliant absorption of gradual road inputs and controlled damping over sharp bumps and off-road impacts without manual adjustment
• Orifice disk design ensures optimal hydraulic fluid flow through the full range of suspension travel, delivering consistent damping response on paved roads, gravel, and light to moderate off-road terrain
• Leak-proof hydraulic seal construction minimizes maintenance needs and extends service life across the demanding operating environments these trucks and SUVs encounter
• 5/8 in. diameter hardened and double chrome-plated piston rod provides superior corrosion resistance and surface durability, protecting the hydraulic seal and maintaining consistent performance over long service intervals
• Bonded iron piston delivers superior strength and fatigue resistance through the full range of rear suspension loads on these heavy-duty platforms
• Distinctive red protective boot shields the shock shaft from road debris, mud, and moisture - the Hydro 7000 series signature finish
• Eyelet upper and Eyelet/Sleeve lower mount design is a direct match for the rear solid-axle shock mounting geometry used across the entire 1973-1991 Chevrolet/GMC K-series and V-series squarebody platform
• At 27.19 in. extended and 16.16 in. compressed with 11.03 in. of stroke, the H7053 is dimensioned to provide full rear suspension travel at factory ride height on these platforms
• Backed by Skyjacker's Limited Lifetime Warranty against defects in materials and workmanship

Product Description

The Skyjacker H7053 Hydro 7000 is the rear shock absorber for the classic Chevrolet and GMC 4WD squarebody truck platform spanning 1973 through 1991 - covering the full K-series (K10/K20/K30) and the transitional V-series (V1500/V2500/V3500) designations across pickups, Suburbans, K5 Blazers, and GMC Jimmy SUVs. It is the direct rear companion to the Skyjacker H7051 front shock, and the two are paired by Skyjacker as a matched front/rear set for complete squarebody 4WD shock upgrades. The shared rear mount geometry - Eyelet upper, Eyelet/Sleeve lower - is consistent across the entire platform run, allowing the H7053 to serve as a single rear shock solution for all of these vehicles at factory ride height.

Built on Skyjacker's Hydro 7000 hydraulic technology, the H7053 uses an orifice disk and true velocity-sensitive valving to adjust damping in real time based on suspension speed. This produces a more progressive and compliant response than fixed-orifice OEM-replacement shocks - absorbing small road inputs softly while resisting large, fast impacts firmly. The 5/8 in. diameter hardened and double chrome-plated piston rod is a step above the standard single-chrome rods found in economy-grade replacements, providing superior resistance to corrosion and surface pitting, and the bonded iron piston is built for the long service intervals these trucks demand. At 27.19 in. extended and 16.16 in. compressed with 11.03 in. of stroke, the H7053 is properly dimensioned for the rear suspension geometry of the squarebody platform at stock ride height.

The Chevrolet K-series (K10/K20/K30/K5 Blazer) and GMC K15/K25/K35/Jimmy designations used through the late 1970s and 1980s, and the V-series names that succeeded them from 1987 onward, all share the same rear shock mounting geometry - the H7053 covers both naming periods across the full 1973-1991 span. Factory mounting hardware is reused; all installation hardware is included. Sold individually - two required for a complete rear axle upgrade. Backed by Skyjacker's Limited Lifetime Warranty for the original retail purchaser.
