STAGE 3 - FALCON 2.1 SHOCKS, 2015-2018, LIGHT/MID/HEAVY TUNE, OPTI-RATE - SPRINTER 3500 4WD

Looking to correct rear sag and upgrade the handling of your Mercedes Sprinter 3500 4x4? The Van Compass SPRINTER 3500 4WD - STAGE 3 - FALCON 2.1 SHOCKS, 2015-2018, LIGHT TUNE, OPTI-RATE (7023-3500-L) is purpose-built for 2015–2018 Sprinter 3500 dually models, offering dramatically improved ride control, stability, and comfort for lightly built Class B RVs, adventure vans, and passenger vans operating near GVWR.

At the heart of this system are Van Compass–tuned Falcon 2.1 Monotube Shocks (Light Tune), delivering exceptional control over both large and small bumps. With increased damper volume and precision valving, these shocks reduce sway, corner lean, and harsh impacts — ideal for Sprinters traveling rough roads or occasional off-road terrain.

The included Opti-Rate rear leaf spring pack restores lost ride height — typically adding ~1.25” of lift — and is designed to flex appropriately across a range of loads. This corrects sagging rear suspension, helps maintain proper geometry, and contributes to a smoother, factory-like ride with increased stability under moderate weight.

Also included are Van Compass Bump Buddy jounce bumpers — progressive foam replacements for factory rubber stops. These increase bottom-out resistance and smooth spring progression, helping to reduce clunking and sway for a quieter, more composed driving experience.

Need a robust suspension upgrade for your Sprinter 3500 4x4? The Van Compass SPRINTER 3500 4WD - STAGE 3 - FALCON 2.1 SHOCKS, 2015-2018, MID TUNE, OPTI-RATE (7023-3500-M) is designed specifically for 2015–2018 Sprinter 3500 dual rear wheel (DRW) models. Ideal for heavier adventure builds, Class B/C RVs, and passenger vans operating near or at GVWR, this system boosts ride control, corrects sag, and improves handling without sacrificing comfort.

The system is built around Van Compass–tuned Falcon 2.1 Monotube Shocks (Mid Tune), delivering greater damping force for heavier rigs. With increased piston volume and precision valving, these shocks minimize sway, smooth out harsh impacts, and reduce corner lean—providing confidence and comfort whether you're hitting broken pavement, winding highways, or venturing off-road.

The included Opti-Rate rear leaf spring pack restores lost ride height—typically around 1.25"—while supporting varying weight configurations. These springs correct suspension geometry, stabilize load handling, and maintain a smooth, factory-like ride under demanding weight conditions.

Bump Buddy jounce bumpers round out the kit, replacing the stiff OEM bump stops with progressive foam units. These absorb impacts more smoothly, improve spring progression, and reduce sway—resulting in a quieter, more refined ride with enhanced bottom-out resistance.

• HD Rear A/C Package: Extra care is needed when installing front shocks—refrigerant lines may need gentle repositioning.

• Not compatible with Sumo Spring Rebel series (SSR-327-47-2 & SSR-327-40-2), which interfere with rear shock placement.

• VC-tuned Falcon 2.1 Monotube Shocks, Mid Tune (Front & Rear)

• Opti-Rate Rear Leaf Spring Pack (~1.25" lift for ride height recovery)

• Enhanced damping for heavier rigs and rough conditions

• Reduced sway, corner lean, and harsh impacts

• Improved bottom-out control with smoother progression

• Restores proper stance and geometry under load

• Reduced driver fatigue and improved overall ride quality

For serious van builds running at or near max capacity, the Van Compass SPRINTER 3500 4WD - STAGE 3 - FALCON 2.1 SHOCKS, 2015-2018, HEAVY TUNE, OPTI-RATE (7023-3500-H) is the ultimate upgrade for your 2015–2018 Sprinter 3500 4x4. Tailored for heavily built adventure vans, fully loaded Class B/C RVs, and passenger vans pushing their GVWR, this system transforms ride quality, handling, and suspension performance across any terrain.

At the core of the Stage 3 system are Van Compass–tuned Falcon 2.1 Monotube Shocks (Heavy Tune)—engineered specifically for vans carrying significant weight. These shocks feature oversized pistons and aggressive valving to combat body roll, reduce wind sway, and tame harsh road impacts. From broken pavement to off-grid trails, they deliver superior control, improved stability, and less driver fatigue on long journeys.

The included Opti-Rate rear leaf spring pack corrects rear sag and brings back proper ride height—typically offering a 1.25" lift. Designed for flexibility across high-load applications, these springs maintain suspension geometry, minimize wallowing under load, and deliver a quiet, controlled ride—no matter how much gear you’re carrying.

The Bump Buddy jounce bumpers replace stiff factory rubber stops with progressive foam units. These bumpers improve spring progression, enhance bottom-out resistance, and absorb sharp hits without introducing noise or harshness—giving you a smoother, quieter ride.
