ARANA’s ST360M110010 set includes two 36-inch gas struts with a 100 lb per pair rating. This configuration suits heavy lids on clamshell snowmobile trailers, truck covers, and outdoor enclosures, particularly where a moderate lift is sufficient, while maintaining reliable performance with a center-to-center extended length of 36 inches and a 20-inch compressed length. Interchange numbers P8155, ST360M110010, and ST360M1100S10 aid in cross-compatibility with existing trailer hardware.

Black Ice 5-Foot Snowmobile Trailer Ski Guides

While not a lift strut, these ski guides from Black Ice support friction-free loading and protection for trailers and trucks during transport. Each guide is 5 feet long and broad enough to offer substantial coverage, reducing ski carbide scraping during loading and unloading. They complement lift systems by improving overall trailer handling in winter conditions and can be integrated into broader clamshell setups for smoother operations.
Buying Guide: Key Purchase Considerations For Clamshell Snowmobile Trailers
- Lid weight range: Match the lift capacity to the lid weight (for example, 160–200 lb ranges for many ARANA and BDFHYK models). Do not exceed the recommended weight to avoid underperformance or damage.
- Length and travel: Ensure extended and compressed lengths align with your trailer lid and mounting points. Common options include 28–36 inches extended, with 14–21 inch compression ranges depending on model.
- Mounting Type: Many units are non-ball-stud designs; verify compatibility with your existing hardware and mounting plates. Ball stud availability can influence the installation process.
- OEM compatibility: Check OEM reference numbers (e.g., C16-22632, ST360M250, P8155) to ensure exact fit or suitable cross-compatibility with your trailer’s hardware.
- Durability and warranty: Look for 12–24 month warranties and indications of lifetime service. In cold environments, choose models rated for reliability and resistance to freezing conditions.
- Application scope: While designed for snowmobile trailers, many of these struts also serve truck covers, tonneau covers, and hatch doors. Consider a model with broader application if you own multiple lids.
- Installation guidance: Some listings provide detailed installation tips or guides. If you’re DIY-ing, ensure you have the necessary tools and mounting adjustments to control the force applied during operation.
- Pairing options: Several products are offered as sets of two; using a matched pair ensures balanced lifting and consistent performance across the lid’s travel.
For most buyers, prioritizing lid weight compatibility, correct length, and OEM reference numbers will yield the best results. When in doubt, measure lid weight, verify OEM numbers, and review installation guidance to ensure a reliable, long-lasting lift system for snowmobile trailer clamshell lids.
