SumoSprings Front #SSF-106-40 | Sprinter 2500/3500 + Ford E-Series | Urethane Pair

Take the sag, sway, and harshness out of a heavily loaded front end with SumoSprings Front (Part SSF-106-40). Microcellular urethane suspension helper springs that replace the factory front bump stops — no airlines, no compressor, no maintenance. Supplied as a pair (left + right). Available at The RV Surplus.

⭐ Fitment

• Mercedes-Benz Sprinter 2500
• Mercedes-Benz Sprinter 3500
• Ford E-Series vans — E-150 through E-450
• Manufacturer lists further chassis by year — confirm your exact year and model before ordering
• On Sprinter 3500, pair with SSR-338-47 Rear for the matched set

⭐ Why an RV Owner Fits These

A Class C or van conversion carries most of its weight high and behind the front axle, and that shows up at the front end as porpoising over dips and wandering in crosswinds. SumoSprings work with the factory suspension rather than replacing it:

• Compresses up to 80% of original height with full memory rebound
• Progressive spring rate with superior damping
• Will not leak or rupture (no air components)

⚠️ Helper Springs vs Leveling Systems

Suspension helpers reduce body roll while moving. They do not level a parked coach — that's what a hydraulic leveling system does. For Sprinter 3500 cutaway chassis, the EQ Smart-Level Sprinter 3500 Single Stage is the matched leveling system — patented, no cutting/drilling/welding to the frame rail.

⚠️ GVWR Warning

Never load any vehicle beyond the manufacturer's GVWR. Helper springs improve ride, not payload capacity.
