If you own a high-roof Sprinter, you already know the move: grab the doorframe, hoist yourself up, and hope your knee cooperates. Do it once and it is nothing. Do it forty times on a camping weekend, with a dog and an armful of gear, and it adds up fast. A good side step turns that climb into a single, easy motion.
The problem is that "side step" covers a lot of very different products, and the wrong one will either rust out, hang too low, or feel sketchy underfoot. Here is how to choose, and how the common options stack up.
First, know what you actually need
There are three different products people lump together, and they solve different problems:
- Entry steps (side steps): built to make getting in and out easy while keeping ground clearance. Lightweight, tucked close to the body.
- Nerf bars / tube steps: round tubes borrowed from the truck world. Cheap and easy to find, but the geometry is rarely right for a Sprinter.
- Rock sliders: heavy steel bars built to take impacts on technical trails. Great protection, but heavy and low.
If you want daily access, you want an entry step. If you are running hard off-road trails and need body protection, you want rock sliders. Trying to make one product do both usually gets you a compromise at both.
What to look for
Material: aluminum vs. steel
Steel steps look great until the powder coat chips. Then rust creeps in, and it moves fast if you park near salt water or drive salted winter roads. Aluminum does not rust, period. If you spend any time on the coast or in snow country, this is the single most important spec on the page.
Step width and surface
A skinny tube gives you a round bar to balance on. A wide, solid pad gives you a real surface for a boot, and no gap for a dog's paw or a sandal to slip through. If pets or kids use the van, go wide and solid. Around 6 to 7 inches of usable width is the sweet spot.
Mount type and ground clearance
A flush pinch-weld mount tucks the step tight to the body, so it keeps your clearance and does not catch curbs or trail lips. Low-hanging nerf bars sit lower and take the hits. Look for a mount that bolts to the factory pinch weld and sits high and tight.
Step height
Too high and every entry is a climb. Too low and it drags on driveways and dips. On a stock-height Sprinter, roughly 13 to 14 inches from the ground to the step is comfortable for most people. If you run a suspension lift, factor that in.
Ladder compatibility
If you plan to add a roof ladder now or later, choose a step that lines up as the natural first rung, so getting on the roof is one smooth motion. Steps and ladders that are designed together save you a headache.
Install and support
Check three things: whether it needs drilling, how long the install takes, and whether professional install is available. A permanent bolt-through mount is more secure than a clamp on a vehicle this heavy. And if drilling into your van makes you nervous, having a shop that will do it for you is worth a lot.
How the options compare
| Aluminum flush steps (e.g. SV Side Steps) | Steel tube / nerf bars | Rock sliders | |
|---|---|---|---|
| Best for | Daily access, van life, dogs | Budget, occasional use | Hard off-road, body protection |
| Rust | None (aluminum) | Rusts once coating chips | Rusts once coating chips |
| Weight | Light | Medium | Heavy |
| Ground clearance | High (flush mount) | Lower (hangs below) | Lowest |
| Step surface | Wide solid pad | Round tube | Flat bar, varies |
| Install | Bolts to pinch weld | Bolts on, fit varies | Often needs a lift to clear |
| Dog-friendly | Yes, solid surface | Not really | No |
There is no single "best." A trail-focused rig that lives on rocks is a rock-slider situation. A van you actually live and travel out of is an entry-step situation, and for that, a light, rust-proof, wide-pad step that keeps your clearance is hard to beat.
A note on fitment
Sprinter side steps mount to the chassis pinch weld, which means they fit far more than just factory vans. Many popular RV and upfitter builds are Sprinter-based, including the Winnebago Revel, Storyteller Overland, Outside Van, Airstream Interstate and Atlas, Grech RV, Pleasure-Way, and Leisure Travel Vans. Fitment still depends on your exact model year, any suspension lift, and body kits, so confirm before you order. Not sure about your build? Reach out to our team.
Our take
We built the SV Sprinter Van Side Steps because we got tired of recommending workarounds that did not exist yet. They are 3/16 inch aluminum, so they never rust. The 6.5 inch solid pad is wide enough for a boot or a dog. They mount flush to the pinch weld to keep your clearance, and they pair with the SV Side Ladder if roof access is on your list.
