Agile, Owl, King, Evictus, Van Compass
Every brand is solving sag, sway, and fade. They just start from a different idea of your van. Once you see each suspension brand philosophy laid out, the brand argument gets quieter.
Each brand is making a bet about your driving style:
- same van on every drive
- mixed highway and dirt
- primarily dirt and washboard roads
This page lets you compare Agile, Owl, King, Evictus, Van Compass and others on the same terms.
Agile Off Road
Agile Sprinter 2500 Pro RIP kit
Agile starts with the finished van’s weight. The Pro RIP kit pairs a weight-matched rear leaf pack with fixed-tune FOX dampers, BILSTEIN B6 front struts, front coil assist, and reinforced rear shock mounts.
- Best fit: Loaded vans whose owners want consistent road manners without adjusting shocks between drives.
- More control: Agile also offers adjustable Performance Elite and Factory Race packages for mixed highway and trail use.
- Warranty: Coverage is component-specific. Eligible BILSTEIN B6 struts have a limited lifetime manufacturer warranty. FOX coverage varies by series and purchase date; qualifying Performance Series shocks have limited lifetime coverage, with exclusions. Wolf Pack’s Factory Race offering carries two-year parts coverage. We confirm spring, hardware, and exact shock coverage with your quote.

Owl Falcon Arrow
Arrow Lifted Pro / Trail Pro 2500 kit
Owl’s approach is that the same van does different jobs on the highway and the trail. Progressive Deaver leaf packs support the load, while adjustable Falcon dampers let the driver change the feel for pavement, washboard, and rough roads.
- Best fit: Mixed highway travel and regular dirt, with an owner who will use the external adjusters.
- The trade-off: The Pro adds lift and upgraded front struts, with a higher price and more driver involvement.
- Warranty: Four years / 40,000 miles for the eligible Owl Arrow system installed by Wolf Pack, whichever comes first. Limited parts coverage; Owl’s terms apply.

King Shocks
King 2.5 front coilovers and rear shocks
King brings desert-racing hardware to the Sprinter: reservoir shocks, compression adjustment, and rebuildable bodies. A shop pairs the dampers with suitable rear leaf springs to make a complete system.
- Best fit: Owners who value rebuildability and heat capacity for sustained rough-road driving.
- Watch for: Spring and shock selection must work together. If the chosen setup adds rear helper coils, their support must be included when selecting the leaf pack.
- Warranty: 90 days from purchase against manufacturing defects. Coatings are covered at the time of sale only. Maintenance and use exclusions apply.

Evictus
Sprinter Prerunner kit shown
Evictus uses large-diameter dampers with a dual-piston, anti-cavitation reservoir design. Its approach is self-adapting damping: control against initial body roll, with compliance over larger impacts, without daily clicker adjustments.
- Best fit: Owners seeking more damper capacity for vans regularly driven on rough roads.
- Watch for: Rear helper coils add spring support. Match the complete spring system to the loaded van rather than stacking spring rates blindly.
- Warranty: Advanced: one year / 12,000 post-installation miles. Prerunner: two years / 25,000 post-installation miles. Whichever limit comes first; original-owner coverage with maintenance and use conditions.

Van Compass
Stage 4.3 Sprinter 2500 kit shown
Van Compass builds staged systems. Owners can start with dampers and spring support, then choose additional lift, brackets, and struts as their needs change. Adjustable Falcon options cover the highway-to-dirt transition.
- Best fit: Owners who want an incremental upgrade path and a package matched to their van’s weight and terrain.
- Closer look: Check the condition of the factory leaf springs before adding a mini-pack. Include the appropriate shock-mount reinforcement and the labor cost of future upgrades.
- Warranty: Falcon shocks: one year, parts only; diagnostic labor, warranty labor, and shipping excluded. Fabricated hard parts have original-owner coverage; springs and other components have separate terms.

Belltech
Sprinter 2500 two-inch lift / coilover kit shown
Belltech’s Sprinter systems combine coilovers, lift hardware, and chassis-specific brackets. This is a different route to ride height and support than replacing the rear leaf pack with one selected for the van’s loaded weight.
- Best fit: Owners considering a coordinated lift and damper package for the exact Sprinter application.
- The test: Check the spring range, resulting geometry, and kit contents against your axle weights. Belltech and third-party bundles can contain different parts.
- Warranty: Belltech lists three years / unlimited mileage for Street Performance, Trail Performance, and Nitro Drop 2 shocks and struts; five years / unlimited mileage for Street Performance and Trail Performance coilovers. Authorized-dealer purchase and other conditions apply.

Replacement Shocks & Struts
BILSTEIN B6 struts shown; individual components
BILSTEIN, KONI, FOX, and OEM replacement dampers can be a sensible refresh when the van’s springs still provide the right support and ride height. A damper controls movement; it does not add spring rate.
- Best fit: A van with healthy, correctly loaded springs and worn or poorly matched dampers.
- The limit: Replacing shocks alone does not correct inadequate spring support or restore travel when the rear sits on its bump stops.
- Warranty: Varies by manufacturer and exact part. Eligible BILSTEIN B6/B8 products carry a limited lifetime manufacturer warranty; FOX coverage depends on series and purchase date. We confirm the applicable terms for KONI, OEM, or other quoted components.
| Approach | Primary job | Usually right when | Usually wrong when |
|---|---|---|---|
| Full progressive leaf + matched shocks (Agile / Owl style) | Restore rate and control as a system | Finished, living weight van, highway plus mixed dirt | You need 4 to 6 inches of lift or 35s more than you need composure |
| Owl Falcon / Agile Fox adjustable | Same, with day to day clickers | You will actually change settings | Knobs will stay at the factory mark forever |
| King 2.5 / 3.0 + leaf or rear coil | Heat capacity, rebuildability, trimmable height | Hard dirt, serviceable hardware mindset | Coil stacked on an already correct max pack |
| Evictus Advanced / Prerunner | Large piston digressive control, optional helper coil | Serious off pavement, budget matches the parts | The spring rate conversation gets skipped |
| Van Compass staged kit | Incremental, adjustable, lift friendly retail system | Lighter 4x4, owner wants a catalog ladder | Heavy living weight treated with a mini pack |
| Add-a-leaf / mini-pack only | Cheap sag band-aid | Mild squat, short horizon, tight budget | Pack is flat, build is heavy, you want this done |
| Sumo / urethane helper only | Helper bump stop rate | Light van, secondary to a real pack | Used as the entire rear upgrade |
| Frame rail airbags | Adjustable height | Side to side imbalance or light tow rake | Used instead of correcting the spring support on a heavy camper |
| Sway bar only | Reduce body roll | Springs already correct, roll still bothers you | Van is on bump stops and you were told to start here |
Wolf Pack: lifetime installation labor
Our lifetime installation labor warranty covers labor to correct our suspension installation errors. It transfers to future owners of the van. Manufacturer parts warranties are separate and subject to their applicable terms.

Nobody wins. Agile is the set and forget rate matched system. Owl is the adjustable mixed use system. King is rebuildable race hardware that needs a thoughtful leaf pairing. Evictus is large piston capability at a large piston price. Choose the job, then the tool.
Start with the manufacturer's baseline for your exact shocks, then make small changes and test on a familiar route. Firmer isn't always better, and fully soft isn't automatically right for washboard. On FOX DSC systems, high-speed and low-speed refer to suspension movement, not van speed. If you won't use the adjusters, we usually recommend a fixed-tune setup.
Yes. Raising ride height generally raises the van's center of gravity. Correctly matched springs restore support and usable suspension travel, which can improve control, but they don't lower the center of gravity. That's why we match the suspension to the van's loaded weight instead of adding height for its own sake.
