R3847 4 Springs Kit for Hydraulic Jacks GOLKNHA Black 13-3/8

Description

Product Overview

The R3847 4‑spring replacement kit is engineered for professional-grade hydraulic leveling jacks that support loads of 6,000 lb and 9,000 lb. Each spring is forged from high‑strength alloy steel and finished with a durable black powder coating, delivering resistance to corrosion, wear, and extreme temperature fluctuations. The kit includes four springs, each measuring 13‑3/8″ in length and 1‑1/16″ in diameter, precisely machined to match the original specifications of OEM parts. This exact fit eliminates the need for modifications, ensuring a seamless installation that restores the jack to factory performance levels.

Usage

Designed for a broad range of heavy‑duty vehicles—including buses, recreational vehicles, and trucks—this spring kit is ideal for service technicians, fleet managers, and DIY enthusiasts who demand reliable lift capability. Whether you are performing routine maintenance on a 6,000 lb jack or upgrading a 9,000 lb unit for higher load capacity, the springs provide consistent pressure distribution, reducing the risk of uneven wear and premature failure. The kit’s universal fit for both 13″ and 15″ stroke jacks means you can service multiple models with a single inventory item, simplifying parts management and reducing downtime on the shop floor.
