Even though the Grenadier comes off the line trail-ready, most builds quickly outgrow the stock suspension once you add:

• Steel bumpers
• Roof racks & rooftop tents
• Auxiliary fuel or water storage
• Interior drawer systems
• Off-road recovery gear

An upgraded suspension system helps balance the added weight, increase ride quality, and keep your rig composed no matter the terrain.

We trust Reiger and Eibach suspension systems for the Grenadier. These brands are battle-tested and built for precision, control, and long-lasting durability in extreme environments:

• Reiger Suspension – High-performance, rally-proven shock systems with fine-tuned damping control
• Eibach Suspension – Engineered for strength and comfort with progressive springs and perfectly matched shock tuning

Our techs know how to pair and tune each system for your rig’s unique setup—whether you're building for long-range overland travel or short-wheelbase trail crawling.

• Full removal and replacement of stock suspension
• Ride height and load assessment
• Coil spring and shock absorber install
• Alignment post-installation
• Optional sway bar or control arm upgrades

We’ll even help you spec out the ideal setup based on how you drive, what you carry, and where you're headed.

We’re not just a retail shop. We’re suspension and drivetrain experts who live this stuff. Our team has real-world off-road experience, and we work on Sprinters, trucks, and specialty 4x4s every day.
