Like many LUVERNE side steps and running boards, O-Mega II 6" oval side steps are made to work hard and to do it with style. They are constructed from strong, lightweight, rust-free aluminum, and to truly make them a step up from the rest, we shield them in a highly durable powder coat finish. This ensures maximum corrosion resistance and excellent protection against scuffs and scratches. The side steps are available in two powder coat finish options, including textured black and silver powder coat. O-Mega II side steps are also made to provide saf e, comfortable entry and exit from your vehicle. They feature tough aluminum step pads with protruded circular treads that will never wear or crack. The step pads offer a non-skid surface, and they are finished with a textured black powder coat for lasting corrosion resistance. Also unique to our O-Mega II step pads is their customizable positioning. The pads are packaged unattached from the tubes and mount with self-tapping screws. This allows you to precisely match the layout of your vehicle to suit your preferences. You can mount them to the provided factory specifications or adjust them to a custom placement. The 6" x 2-3/4" tubes are fitted with black TPO plastic end caps, adding a modern, professional look. The end caps are also paintable to allow for even further customization. Each set of O-Mega II side steps is designed for vehicle-specific installation and fitment, using a unique set of mounting brackets. This particular set of side steps fits specific years of the Chevy Silverado 2500 HD or 3500 HD and GMC Sierra 2500 HD or 3500 HD (see application info to verify fitment). NOTE: Mounting brackets are included but ship separately.
LUVERNE O-Mega II 6" oval side steps are made to work hard and to do it with style. They are constructed from strong, lightweight, rust-free aluminum and shielded in a highly durable powder coat finish of textured black or smooth silver.
LUVERNE has manufactured truck accessories in the United States since 1963, specialising in grille guards, running boards, side steps and mud guards for pickups, commercial vans and SUVs. Products are built primarily from stainless steel, aluminium and mild steel, with model-specific mounting kits that use existing frame locations for a bolt-on installation.
LUVERNE has been manufacturing automotive accessories in the United States since 1963, and six decades of continuous production have made it a nationally recognised name in the truck accessory market. Now a Lippert brand, it concentrates on a defined set of products rather than spreading across the whole aftermarket: front-end protection, step access and spray protection for pickup trucks, commercial vans and sport utility vehicles.
Step products are the largest part of the catalog and the range is unusually deep, because the right step depends on the vehicle's ride height, the width of the rocker panel and how often people get in and out. The O-Mega II six-inch oval steps give a wide, flat standing surface in polished stainless or black powder coat, while the Regal 7 seven-inch oval steps go wider still for full-size crew cabs and lifted trucks. The broader running board and side bar range covers round tube, oval and boxed profiles across cab configurations, with treads positioned at the door openings where they are used.
Grille guards protect the front end against impacts, brush and road debris, built in tubular stainless or steel with model-specific brackets that tie into factory frame mounting points. Because the fit is engineered per vehicle, installation is a bolt-on job that does not require drilling or cutting on most applications.
Rounding out the line, LUVERNE mud guards and mud flaps shield rocker panels, paint and following vehicles from stones and road spray, in widths matched to the tyre and fender they sit behind. Material choice runs through everything the brand does: stainless steel where appearance and corrosion resistance matter most, aluminium where weight is the priority, and mild steel with protective coating where strength and value lead. Customers include contractors, fleet operators, van upfitters and truck owners.

Yes, model 571743 MEGA STEP Brackets are designed for 2015+ GM 2500/3500HD Crew Cab and Double Cab Pickups with both gas and diesel engines. The brackets use a body mount application and are a no-drill installation. Confirm your truck is a 2500 or 3500HD model and either Crew Cab or Double Cab configuration.
The O-MEGA II 6" Oval Steps (models 583072, 583078, 583088, 584072, 584078, 584088) are listed as a universal application. However, they must be paired with a vehicle-specific bracket package. The step pad positioning varies by vehicle model and cab style—consult the Step Pad Location Guide table on page 2 for your specific vehicle to determine correct pad placement.
For a Silverado Crew Cab, position Pad A at 14-3/4 inches and Pad B at 54-1/4 inches from the reference point. Note that the manual states these locations are suggestions only and may be placed at the purchaser's discretion.
Yes. The MEGA STEP Bracket model 571743 is designed specifically for 2015+ GM 2500/3500HD Crew Cab and Double Cab Pickups. For a 1500 model, you will need a different bracket package. Additionally, if installing 571743 brackets on a 1500 pickup, you must attach the small 90° bracket (item #16) to the front brackets.
The O-MEGA II steps include: 2 extrusions (available in silver or black, in three lengths: 69.0", 75.0", or 85.0"), 4 step pads (item #552970), 4 end caps (item #107956), 24 square head screws 5/16-18 × 1" (item #106880), 24 serrated flange nuts 5/16-18 (item #102680), and 20 tek screws #8-18 × 1/2" (item #107958) for attaching step pads.
The 571743 bracket kit includes: front, center, and rear mounting brackets (left and right), load reaction studs (6 double-ended studs, 3/8-16 × 4.0"), rubber cushion washers, flat washers, serrated flange nuts, hex head screws, and optional 90° brackets for 1500 applications. Refer to the Service Parts List on page 4 for complete part numbers and quantities.
The manual requires a drill with a 1/8" bit to drill five holes in the step plates for step pad attachment. A wrench or socket set is needed to tighten nuts and bolts to the specified torque values (5 lb-ft for end caps, 19 lb-ft for serrated flange nuts on square head screws). The manual does not specify other tools required for bracket installation—refer to the instructions included with your specific bracket package.
Required tools include a wrench or socket set to tighten fasteners to 19 lb-ft torque. The installation is described as a no-drill application, so no drilling is required. You will need a tool to remove the factory body mount bolts, which may require extra caution due to excessive thread locker on 2010+ GM Silverado/Sierra models.
Before starting installation, read the instructions completely and verify that all required parts listed on the Service Parts List are on hand. You will also need to follow the instructions included with the specific bracket package for your vehicle, as bracket mounting is a separate process from step installation.
