Megawatt™ Performance Rock Sliders with Step for Gen 1 R1S

$2,199.00

The Rivian R1 is the perfect vehicle to tackle the outdoors. It's high ground clearance and individual wheel control enable it to navigate rocky terrain with ease. Even the most capable vehicles and drivers, however, can get hung-up on rocks and logs, which can result serious rocker panel damage or worse. Rock sliders help guard against this off-road hazard to keep your truck protected.

Unsatisfied with current Rivian offerings, a team of early owners and longtime off-roaders assembled to engineer the strongest rock slider on the market that can serve as an R1S running board, yet stand up to even the most punishing abuse. What they arrived at is the latest product from Megawatt™ performance products.

Make no mistake, this product is a rock slider first with the added benefit of serving as a convenient Rivian step. Given the weight of the Rivian R1S, and the potential for extreme forces while off-roading, we felt a purpose-built protection solution be crafted first. Only then could added features like a running board step be added.

The Rivian R1S has a curb weight of almost 7,100 lbs. That is close the weight of a Dodge RAM 3500 MegaCab. As such, we used proven slider methods for vehicles like these to benchmark the Megawatt™ Rivian R1S rock slider. We then adapted this formula to fit the lines and unique architecture of the Rivian. The result is not only a rock solid, highly functional slider, but a side-step that looks great.

This product fits 2024 and older R1S vehicles only

COMPETITIVE ADVANTAGE ANALYSIS
Feature MEGAWATT™ COMPETITOR 1 COMPETITOR 2 COMPETITOR 3
🔨 Construction ✅ Fully enclosed tubing ✅ Fully enclosed tubing ❌ Press broken sheet metal ❌ Press broken sheet metal
Why It Matters: Sheet metal is often used because it costs less than enclosed tubing. Unfortunately, this folded structure relies on just a few corner welds that can split apart on impact.
🔩 Mounting Points ✅ Two rows of bolts ❌ One row offset ✅ Two rows of bolts ✅ Two rows of bolts
Why It Matters: Single row mounting allows the slider to flex when pushed upward, leading to body damage.
⚙️ Rail Mounting ✅ Inline with frame ❌ Cantilevered outside ✅ Inline with frame ✅ Inline with frame
Why It Matters: Offsetting mounts creates additional outside leverage when the rail is pushed up, which can cause flex and frame damage.
📏 Rail Thickness ✅ .188" ❌ .134" 🤷‍♂️ Undisclosed 🤷‍♂️ Undisclosed
Why It Matters: Thicker rails withstand more force without crushing or bending.
⚡ Weld Type ✅ TIG ❌ MIG ❌ MIG ❌ MIG
Why It Matters: TIG welding results in cleaner, stronger welds than MIG.
🛡️ Coverage ✅ Full wheel-to-wheel ❌ Mostly wheel-to-wheel ❌ Mostly wheel-to-wheel ❌ Mostly wheel-to-wheel
Why It Matters: Partial coverage leaves vulnerable areas open to rock damage.
👢 Kick-out ✅ Yes ❌ No ❌ No ❌ No
Why It Matters: Provides stepping platform, additional protection, and obstacle pivot point.
🔧 Underside Cover No No Yes No
Why It Matters: Underside plating traps debris while providing only marginal protection.
💰 Price Point $$$ $ $$ $$
Why It Matters: Premium price reflects premium materials and construction.

FINISH

Each slider is enveloped in flat black via a unique four-stage process.

  1. Each slider and its top plate is coated in primer.
  2. Top plates are welded to the slider
  3. Assembled sliders are powder coated in a high-heat oven
  4. A probe is inserted and run the length of the tube to coat the inside with paint

We realize this might sound like a lot of work to coat a piece of metal. (It is)! However, this process ensures maximum coverage, which in-turn improves corrosion resistance and longevity.
