Important Notes & Pro Tips
Factory Door Width Variance: Due to manufacturing tolerances in Mercedes-Benz Sprinter sliding door frames,opening widths can vary by up to 22 mm. While most steps drop right in without issue, narrower door openings may require minor edge trimming for a flush fit.
Weather Seal Clearance: Test-fit the step before final fastening. If the outer corner contacts the rubber weather seal around the sliding door, lightly grind or file the corner down to create sufficient clearance.
Subfloors Thicker Than 1 1/4": If your insulated subfloor exceeds 1 1/4" in height, place shims between the bottom of the storage step and the factory stepwell for solid structural support, and add a trim strip to bridge the gap beneath the lower lip.
Fastening Options: For a quick, clean install, apply a generous bead of automotive or marine-grade silicone adhesive underneath the step. For permanent mechanical retention, bolt the step directly to the factory stepwell (always inspect underneath the van for fuel lines, wiring harnesses, or tanks before drilling, and treat bare metal holes with rust-inhibiting primer).
