Tiffin’s GH1 and GH2 are among the most well-appointed adventure vans on the market. Built on the trusted Mercedes-Benz Sprinter platform, they offer a great balance of off-road ability and luxury living space. But if you're looking to push deeper into the backcountry, carry more gear, and make your van even more capable — a few smart upgrades from Dark Star Offroad can take your rig to the next level.
Here are the top five upgrades to enhance the performance, durability, and versatility of your Tiffin GH1 or GH2.
1. Dark Star Offroad Limited Slip Differential
Traction When You Need It Most
When the terrain gets unpredictable, factory open differentials can leave one tire spinning while the other sits still. The Dark Star Offroad Limited Slip Differential helps both rear wheels work together by transferring torque to the wheel with the most grip — automatically and seamlessly.
Whether you're navigating snow, sand, or uneven trails, this upgrade dramatically improves off-road traction without compromising on-road drivability.
Benefits
- Automatically transfers torque to the wheel with the most traction
- Improves off-road capability in snow, sand, mud, and loose terrain
- Enhances safety without affecting on-road performance
- No switches or electronics — just reliable, mechanical grip
2. Dark Star Offroad Rear Coilover Suspension
Transform Ride Quality and Load Handling
The GH1 and GH2 are designed to carry significant weight, but factory suspension can bottom out or sag under the stress of full-time gear, water tanks, and accessories. The Dark Star Offroad Rear Coilover Suspension system replaces the OEM setup with heavy-duty components that offer greater travel, improved damping, and custom-tuned spring rates.
Benefits
- Increased suspension travel for better off-road articulation
- Smoother ride over rough terrain and washboard roads
- Handles heavy loads with less sag and sway
- Custom-tuned for camper van weight distribution
3. Dark Star Offroad Rear Step
Stronger Access, Smarter Materials
The stock Sprinter rear bumper offers limited utility when accessing gear or climbing into the van. The Dark Star Offroad Rear Step, made from aerospace-grade aluminum, offers lightweight durability and precision construction for confident footing in all conditions.
Benefits
- Made from corrosion-resistant aerospace-grade aluminum
- Lightweight and ultra-strong
- Secure, non-slip surface for safe access
4. Dark Star Offroad Backpack Rear Door Rack
Modular Gear Storage, Built to Last
Storage is king when it comes to overlanding, and the Backpack Rear Door Rack gives you versatile, exterior-mounted storage for fuel cans, recovery gear, camp tables, or even a spare tire. Made from aerospace-grade aluminum, it’s incredibly strong without adding unnecessary weight.
Benefits
- Adds modular, exterior-mounted gear storage
- Compatible with recovery boards, fuel/water jugs, tables, and more
- Aerospace-grade aluminum: strong, rustproof, and lightweight
5. Dark Star Offroad Tire Carrier
Free Up Space and Carry Bigger Tires
Upgrading your tire size? Carrying a full-size spare? The Dark Star Offroad Tire Carrier lets you move your spare tire to the rear door, freeing up space underneath and making it easier to access in the field.
Crafted from aerospace-grade aluminum, it’s strong enough for oversized tires while remaining lightweight and corrosion-resistant.
Benefits
- Carries oversized or full-size spare tires securely
- Frees up underbody space for water tanks, air systems, or storage
- Aerospace-grade aluminum construction: rugged and corrosion-resistant
- Clean integration with rear door and compatible with rack systems
