Product Description
Bullet 30° Bent 4-Spring Replacement Arm Kit, Part 1805259
The Bullet™ Arm Kit – 30 Degree Bend, DeBrovys SKU 20-4730/1805259 and Shur-Co part 1805259, is the documented Bullet replacement-arm configuration with a 30° bent arm and four-spring arrangement. Shur-Co’s official Arm System Replacement Parts guide lists 1805259 separately from Bullet straight-arm part 1801595. It is a configuration-specific replacement component—not a universal tarp-arm substitute and not a complete Bullet tarp system.
Confirm the existing part number, 30° upper-arm geometry, pivot mounts, spring arrangement, lower-arm section, rear crossover, roller-bar path, tarp travel, and body clearance before ordering. A visually similar aluminum arm may belong to the straight Bullet configuration, a Trailer Bullet underbody system, or a different arm family with different geometry, mounts, spring components, and operating clearance.

Part 1805259 is selected by documented configuration, not by a generic “Bullet arm” description or a truck photograph. The 30° bend changes arm geometry and clearance behavior, so matching the installed system is essential. If the installed arm is straight, do not substitute this part merely because the system is Bullet and uses a four-spring arrangement.
Part 1805259 Compared with Other Bullet Arm Configurations
| Configuration | Documented distinction | Selection rule |
|---|---|---|
| 1805259 | Bullet 30° bent arm – 4-spring kit | Use only where the installed Bullet system confirms the 30° bent, four-spring configuration. |
| 1801595 | Bullet straight arm – 4-spring kit | Do not substitute for a bent assembly just because the family and spring count are similar. |
| Trailer Bullet underbody system | Shur-Co documents a separate underbody configuration and spring architecture. | Confirm the complete mounting and system type; do not assume a side-mount 1805259 fit. |
| Other arm-system families | Flash, Arm-Matic, Hammer II, tension-arm, and other systems have separate components and mounting details. | Match the installed family, part number, geometry, and hardware rather than a broad “bent tarp arm” description. |
For the distinct straight configuration, see the Bullet Straight Arm Kit, part 1801595. This link is a fitment reference only; it is not a recommendation to interchange the two kits.
Bullet 30° Arm System Context
Shur-Co describes the Bullet as an aluminum flip-tarp system for compatible dump-body applications, available with straight or 30° angled anodized-aluminum arms. Official Bullet materials describe bright anodized aluminum arms, two-piece adjustable arm sections, a low-profile side-mount torsion-spring design, and complete-system components such as a roller bar, motor, switch, and tarp. Those items are complete-system context only; this product is the replacement arm-kit part 1805259.
For complete-system, controls, and related replacement categories, browse Truck Tarp Systems. If a repair also requires related parts, DeBrovys can help compare the confirmed arm geometry, pivot-mount layout, roller-bar path, rear crossover, tarp attachment, and body-side clearance before selection.
Replacement Kit Scope and Receiving Check
Shur-Co’s Arm System Replacement Parts guide states that replacement arm kits include pivot mounts, flat coil springs, a welded or clamshell lower-arm section, pivot arms, an elbow when applicable, rear crossover, and hardware. Confirm exact as-shipped contents against the current packing list, order documentation, and existing system before beginning service.
Do not assume a replacement arm kit includes a tarp, motor, roller bar, controls, cab shield, every body-side component, or every adjacent system part. Inspect the delivered items, original equipment, and repair order together. If a part number, mount, arm profile, spring detail, crossover, or hardware set does not agree with the system, stop and request a fitment review before installation.
30° Bent-Arm Fitment Checklist
| Confirm before ordering | Why it matters |
|---|---|
| Existing part number | Part 1805259 is the strongest starting point for a direct Bullet 30° bent-arm replacement decision. |
| Upper-arm angle | This kit is documented as 30° bent; the separate straight Bullet four-spring kit is part 1801595. |
| Spring and mounting arrangement | Confirm the installed Bullet side-mount arrangement rather than an underbody or other spring architecture. |
| Pivot mounts and lower-arm section | Mount locations, shafts, spring components, arm entry, and supplied hardware must agree with the equipment. |
| Rear crossover and elbow | Arm geometry, elbow where applicable, crossover, roller bar, and tarp path must operate together without binding. |
| Body and cab clearance | Check clearance from cab shields, body sides, tailgate hardware, lights, fenders, toolboxes, exhaust, and accessories through the full travel path. |
| System condition | Damaged pivots, loose hardware, corrosion, bent parts, roller misalignment, or tarp damage may shorten replacement-part life. |
| Qualified service plan | Spring-loaded components require trained personnel, current manufacturer instructions, proper tools, and a controlled work area. |
For a fitment review, send DeBrovys the existing part number, photographs of both arm assemblies and pivot mounts, the rear crossover, roller-bar area, body measurements, and repair history. This helps distinguish the 1805259 bent assembly from 1801595, an underbody system, or another arm family before an order is released.
Expert Geometry Check for Fleet Repairs
Expert fitment insight: Confirm the 30° geometry on both sides of the installed system. A prior repair may leave a fleet with mixed assemblies, altered mounts, an incorrect crossover, or a catalog part that looks close but does not follow the original travel path. Compare the upper-arm bend, pivot mounts, lower-arm section, spring components, elbow, rear crossover, roller-bar alignment, tarp travel, and nearby clearances as one operating assembly.
Record the truck or trailer number, body style, current arm geometry, original part number, inspection date, and clear photographs before ordering. These original service records allow a technician to identify whether the equipment truly needs part 1805259 or another configuration after modifications or prior repairs.
Spring-Tension Safety and Qualified Service
Bullet arm and spring assemblies are safety-critical service components. Do not release, remove, install, index, disassemble, or modify springs, pivots, lower-arm components, or arms without current manufacturer instructions and qualified service personnel. Keep people clear of all arm-travel, pinch, and release zones during inspection, installation, and operation.
If a 30° arm is bent beyond its documented geometry, a mount is cracked, hardware is missing, spring components are damaged, or the tarp tracks incorrectly, take the system out of service until evaluated. Follow current manufacturer instructions appropriate to the installed Bullet system rather than adapting procedures from a different arm family.
Pre-Installation Inspection and Commissioning
Before qualified installation, inspect pivot mounts, arm sections, springs, lower-arm components, elbows, rear crossover, roller bar, tarp attachment, wiring or controls where applicable, and all body-side structure. Verify that the 30° arm path will clear the body, cab shield, tailgate hardware, accessories, and tarp components through the intended range of movement.
After installation, complete the initial operating cycle slowly in a clear work area. Observe arm geometry, crossover movement, tarp tracking, roller-bar movement, body clearance, and hardware. Stop service if the arms bind, rub, contact the body, pull the tarp unevenly, or operate unexpectedly. Verify functional movement only in accordance with current manufacturer instructions.
Maintenance and Service Records
Inspect the entire Bullet system as an operating assembly: pivot mounts, spring components, arm sections, elbows, rear crossover, roller bar, tarp attachment points, wiring or controls, and tarp condition. Watch for loose hardware, corrosion, cracking, deformation, worn pins, change in spring response, and any condition that affects normal arm travel.
Record part 1805259, equipment identification, installation date, condition observations, repair details, and photos in the maintenance file. Accurate records support future parts decisions and help determine whether the system should remain in the 30° configuration or needs broader service.
Official Bullet Catalog and Literature Images
DeBrovys has identified official Shur-Co/Donovan Bullet literature showing the installed Bullet aluminum-arm system, the exact 1805259 30° replacement-arm listing, arm illustrations, and the documented distinction from straight part 1801595. These vendor-source pages are available for product-gallery review. No AI-generated technical image is used or proposed for this product.
See the Flash 30 Degree Bent Arm Kit only as a separate product-family reference; Flash components must not be substituted for a confirmed Bullet 1805259 installation. For product-system planning, read the DeBrovys guide to Donovan and Shur-Co tarp systems and visit the DeBrovys blog.
Custom Fabrication and Related Tarp Components
If the repair also requires a cover, provide the current tarp material, finished dimensions, roller-bar and rear-crossover details, confirmed Bullet configuration, and photographs of existing attachment points. DeBrovys can help identify compatible replacement-tarp options, related hardware, and custom fabrication or heat-sealed panels where applicable. Tarp selection does not replace the need to confirm the 1805259 30° arm kit against the installed system.
Minimum Order Fee Notice
Orders below $130.00 are subject to a $25.00 SHUR-CO minimum order fee. If an order total is $130 or below, DeBrovys will contact the buyer with an additional invoice for the fee before shipment. Before purchasing, confirm the part number, fitment, current price, shipping requirements, and qualified installation plan.
Frequently Asked Questions
What is Shur-Co part 1805259?
Part 1805259 is the Bullet 30° bent-arm, four-spring replacement-arm kit listed in Shur-Co’s official replacement-parts guide. It must be matched to the actual installed Bullet system before ordering.
Is part 1805259 the same as the Bullet straight arm kit?
No. The Bullet straight four-spring kit is part 1801595. The 1805259 kit has a documented 30° bent-arm configuration and should not be substituted based only on shared Bullet branding or spring count.
Does part 1805259 fit every Bullet tarp system?
Do not assume it does. Confirm the part number, 30° arm geometry, pivot mounts, spring architecture, lower-arm section, crossover, and complete system layout before ordering.
What information is needed to confirm fitment?
Provide the installed part number, photographs of both arm assemblies and pivot mounts, the rear crossover, roller-bar area, body measurements, and repair history. These details help distinguish a direct 1805259 replacement from a straight, underbody, or different arm-system configuration.
Can spring-loaded Bullet arm components be installed without trained service?
No. Use current manufacturer instructions, proper tools, qualified personnel, and a controlled work area. Spring-loaded arms, pivots, and related hardware can create injury and equipment-damage risks when serviced incorrectly.
Does the replacement kit include a tarp or complete Bullet system?
Do not assume a tarp or complete system is included. Confirm exact as-shipped contents against the current packing list and order documentation. A compatible tarp must match the installed Bullet roller-bar, crossover, and arm configuration.
