Below, five selected tarp spring systems are presented in detail. Each section highlights fit, construction, and key features to help you compare performance and installation requirements.
Electric Aluminum Arm 4 Spring Dump Truck Kit
The ALL TRUCK PRODUCTS 4-spring kit uses heavy-duty aluminum construction with precision robotic welds for enhanced strength and rust resistance, designed to outlast typical steel arm systems. It fits dump beds up to 23 feet in length and up to 110 inches wide, with a cross tube that can be adjusted to 93–110 inches to accommodate most tarp setups. The cross tube can be shortened for narrower beds, and the aluminum arms promise a lighter weight while maintaining durability. This kit focuses on robust performance for larger dump bodies and frequent tarp operation.
Key features include universal fit via telescoping arms and a cross tube that supports easy tarp mounting. The system emphasizes rust resistance and long-term reliability in harsh job-site conditions. This makes it a strong candidate for fleets needing a sturdy, high-capacity tarp solution that remains functional across a range of bed dimensions.
Electric Aluminum Arm 3 Spring Dump Truck Kit
This 3-spring kit from ALL TRUCK PRODUCTS includes two lower arms, two upper arms, and a cross tube with additional hardware to facilitate a straightforward installation. It’s designed for dump beds up to 20 feet, providing robust arm support while maintaining a lighter setup compared with larger 4-spring configurations. The hardware pack includes corner arm connectors, pivot pins, torsion springs (three per side), and centering flanges to ensure proper alignment and tension across the span.
Compared to bigger kits, the 3-spring option emphasizes a compact, efficient solution for mid-sized dumps. It suits applications where weight savings and simpler installation are priorities while preserving reliable tarp operation during loading and unloading cycles.
4-Spring Aluminum Dump Truck Complete Tarp Arm Kit
From Kym Industries Inc., this complete kit includes durable 93-inch aluminum upper and lower arms, a no-cut, no-drill adjustable cross tube, and corrosion-treated steel pivot pins with all hardware. The setup is designed for reliability and long service life in severe weather and heavy-duty use. The included arms are polished aluminum, contributing to a corrosion-resistant, maintenance-friendly solution for drum and dump body operators seeking a durable, ready-to-install tarp system.
The kit emphasizes a complete “pin to pin” assembly philosophy, ensuring that installers can complete the setup with common tools and standard hardware. This model is particularly appealing for fleets needing a robust, full-arm configuration without the need for custom bending or trimming on site.
ATPSTS Spiral Torsion Springs for Dump Truck Tarp Systems
These spiral torsion springs from ATPSTS are designed to provide tarp arm tension during rolling and unrolling. The set consists of eight springs and uses oil-tempered steel with a corrosion-resistant black powder-coated finish, engineered for long-lasting performance on side-mount tarp arm systems. The springs here are a replacement or upgrade component option, suitable for improving tautness and reliability in otherwise standard tarp systems. The universal compatibility makes them a practical choice for fleets needing to refresh worn springs without replacing entire arms.
Design considerations include corrosion resistance, consistent torque distribution, and compatibility with common side-mount tarp arms. Operators should assess whether their current system uses a compatible torsion-spring layout and ensure proper installation to avoid binding or uneven tension across the tarp roll.
Carolina Tarps Electric Aluminum 4-Spring Tarp System
Carolina Tarps offers a heavy-duty aluminum tarp system with four springs, designed for beds up to 24 feet long and up to 110 inches wide. The kit includes a rotary switch and 50 feet of 6-gauge dual-conductor battery cable, enabling convenient operation from either ground or cab. The aluminum construction provides a lightweight yet robust frame with corrosion resistance, making it suitable for frequent use in varied weather conditions. Installation hardware is included to streamline setup and maintenance, making this a practical option for fleets prioritizing ease of installation and dependable tarp operation.
This system emphasizes user-friendly power control and a practical length-to-width fit range. The kit’s switch and cable configuration support flexible placement, which can enhance operator safety by enabling tarp operation away from the load zone.
Buying Guide: Key Purchase Considerations And Comparisons
Important factors to weigh when selecting a tarp spring kit include bed length, bed width, and whether you need a two- or four-arm arrangement. Heavier-duty, four-spring systems generally provide more consistent tarp tension across longer spans, which helps minimize sag and wind flap on larger dump bodies. For mid-sized beds, a three-spring option can reduce weight while still offering reliable performance.
Arm material and finish matter for longevity. Aluminum arms are lighter and corrosion-resistant, which contributes to easier handling and longer service life in harsh environments. Universal fit features, such as telescoping arms and adjustable cross tubes, help ensure compatibility across multiple dump-bed configurations. Consider whether you want a complete kit with all hardware included or if you need to source torsion springs separately to refresh an existing system.
Installation complexity varies by kit. Some products advertise “pin to pin” or ready-to-install hardware, which simplifies setup. Others may require custom bending or trimming, particularly for non-standard bed widths. Choose a kit with clear installation instructions and compatible hardware to minimize downtime.
Maintenance considerations include corrosion resistance, spring torque consistency, and the availability of replacement parts. Springs wear over time; ensure replacement parts are readily available and that the system provides consistent tension during both rolling and unrolling. Look for kits with rust-resistant finishes and quality-grade springs for dependable, long-term performance.
In terms of overall performance, evaluate how the system accommodates bed width variations and how the cross tube length adjustments affect tarp tension. Some kits offer adjustable cross tubes with cut-down options to fit narrower beds—useful for adapting a single kit to different vehicles within a fleet. Finally, consider warranty coverage and vendor support to ensure you have assistance if components need replacement during peak usage periods.
