Owl Sprinter Van Tech Series: Suspension
When it comes to building out your Sprinter van for serious adventure, one of the most impactful upgrades you can make is to your suspension system. Whether you’re chasing remote trailheads or racking up miles on the highway, a well-engineered suspension transforms not just comfort, but control, safety, and capability.
In this guide, we’ll break down the science and options behind Sprinter van suspension upgrades—so you can hit the dirt (or the asphalt) with complete confidence.
Why Stock Suspension Isn’t Enough for Built-Out Adventure Vans
Straight from the dealer, most Sprinter vans are designed for an empty cargo hold—the factory suspension is a compromise between cost and comfort. Once you add build-out weight (kitchen, bed, gear—think 8,000 to 10,000 pounds fully loaded), you’re riding on the bump stops. That means wallowy handling, harsh impacts, and limited performance whether off-road or on.
Key drawbacks of stock suspension:
Limited spring rate for heavy builds
Shock degradation under off-road use
Rough ride quality and excessive body roll
Minimal adjustability
Suspension Tech: From Leaf Springs to Coilovers
Let’s get technical on suspension choices, all explained in plain English.
Leaf Springs: Old-School Reliability
On the rear axle, Sprinter vans use leaf springs—strips of strong, flexible steel. They’re tried and true, cost-effective, and robust under heavy loads. However, leaf springs lack the responsiveness and ride comfort of more advanced coil systems.
Simple design, easy to maintain
Good for heavy loads
Limited performance and comfort compared to coils
Coilovers: Ultimate Adjustability and Control
Coilovers combine a spring with a shock absorber, letting you dial in ride height and spring rate for your van’s specific load. On some setups, you can tweak a collar or perch to raise or lower the van.
Adjustable spring rate and height
Superior ride quality
Enhanced off-road compliance—keeps tires on the ground over rough terrain
Shocks: Factory, Smooth Body, and Remote Reservoir
Shock absorbers determine how your suspension reacts to varying road surfaces and impacts. Here’s what matters most:
Fluid Volume:Factory shocks are small, with limited oil capacity. Hit a washboard road, and that fluid heats up, causing shocks to fade and potentially fail. Larger shock bodies and remote (or piggyback) reservoirs, like those on premium King and Van Compass setups, hold much more fluid—keeping temperatures down and performance up.
Adjustability:On-road: You want firmer shocks for less body roll and stable highway handling.Off-road: Softer, more compliant settings maximize tire contact and control.
Remote reservoirs deliver:
Increased fluid capacity for sustained off-road performance
Better cooling, reducing fade and wear
Superior adjustability for dialing in both on-road and off-road modes
Comparing Top Suspension Brands: King vs. Van Compass
Owl works closely with renowned brands like King and Van Compass—let’s break down what sets their solutions apart.
Van Compass:
Known for add-on leaf packs or mini-packs—adds progressive spring rate to the rear while keeping the solid axle aligned.
Offers micro adjusters for fine-tuning shock performance.
Bolt-on solutions engineered for adventure van builds.
King:
Signature large-diameter coilover shocks with impressive fluid volume.
Utilizes piggyback reservoirs and an innovative inverted shock design for clearance.
Front springs sized for compliance—absorbing small bumps without overwhelming the suspension.
Both brands offer shocks with easy-to-access adjusters, letting you change stiffness based on where you’re driving. King’s smooth action and robust design make it a favorite among off-road Grenadier enthusiasts, while Van Compass is synonymous with adventure vans.
Expert Tip:Choose adjustable shocks if you’re investing in an upgrade. The ability to switch between highway and trail running pays for itself on every trip.
Anatomy of an Adventure-Ready Suspension System
When building a premium adventure van, focus on:
Helper leaf springs: Engage as your van gets loaded, increasing support and preventing premature bottoming-out.
Double shear shock brackets: These hold the shock on both sides (instead of one), preventing flex and early failure.
Bump stops: More clearance before hitting these means you get a smoother, less jarring ride, even fully loaded.
Compare a factory shock with an aftermarket upgrade, and you’ll see the difference—the tube diameter, integrated reservoir, and tinted finishes all point to serious engineering.
On-Road vs. Off-Road Tuning
What works on one surface may not work on another. On pavement, limiting body roll with firmer shocks feels secure, especially with high-roof vans. Off-road, increased compliance keeps tires planted and handling predictable. Adjustable shocks let you have both.
Quick Scannable Takeaways
Factory suspension = compromise. It won’t handle a fully built van or aggressive terrain.
Leaf springs = reliable but basic. Coils and upgraded shocks offer next-level comfort and control.
Remote reservoir shocks outperform basic designs by managing heat and performance under load.
Adjustability is king for balancing on-road security and off-road compliance.
Brands like King and Van Compass deliver purpose-built solutions for adventure vans.
