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, the CURT 571747 MEGA STEP bracket is designed specifically for 2015+ GM 2500/3500HD pickups with gas or diesel engines. It is a body mount application with no drilling required. However, if you have a 1500 pickup, you must also attach a small 90° bracket (Item #14) to the front brackets.
The manual does not explicitly state whether the 571747 bracket is compatible with 1500 pickups. However, it notes that if installing on a 1500 pickup, you must attach a small 90° bracket (Item #14) to the front brackets. Contact the manufacturer or your installer to confirm 1500 compatibility and whether Item #14 is included or must be ordered separately.
No. The 571747 MEGA STEP bracket is a no-drill, body mount application. It uses existing factory body mount bolt holes and requires no drilling into the vehicle frame or body.
The O-MEGA II step includes: 2 aluminum extrusions (silver or black, various lengths), 6 step pads, 4 end caps, 28 square head bolts (5/16"-18 x 1"), 28 serrated flange nuts (5/16"-18), and 30 TEK screws (#8-18 x 1/2"). The manual recommends checking the service parts list before starting installation to ensure all parts are on hand.
The 571747 bracket kit includes: 2 front mounting brackets (LH/RH), 2 front inboard brackets, 1 center mounting bracket (LH), 1 center mounting bracket (RH), 2 rear inboard mounting brackets, 2 rear outboard mounting brackets, 6 rubber cushion washers, 30 serrated flange nuts (3/8"-16), 6 double-ended studs (3/8"-16 x 4.0"), 12 hex head screws (3/8"-16), 2 small 90° brackets (for 1500 applications), 2 flat washers, 2 spring hanger mounting brackets (inboard and outboard), 2 hex head screws (3/8"-16 x 2"), 22 flat washers (3/8"), 4 flat washers (1/2"), and 2 self-locking nuts (3/8"-16).
The manual does not specify required tools. You will need a drill with a 1/8" bit to drill holes for the step pads, and standard wrenches or sockets to tighten fasteners to the specified torque values (5 lb-ft for end cap nuts, 19 lb-ft for mounting bolts). Consult the bracket package instructions for any additional tools needed for bracket installation.
The manual does not specify required tools. You will need standard wrenches or sockets to tighten fasteners to the specified torque values (19 lb-ft for most bolts). You will also need a way to loosen and remove factory body mount bolts, which the manual warns may have excessive thread locker on 2010+ GM Silverado/Sierra models. A torque wrench is recommended to achieve proper torque specifications.
The manual does not mention disconnecting the battery. The O-MEGA II is a mechanical step system with no electrical components, so battery disconnection is not required.
The manual does not mention disconnecting the battery. The 571747 bracket is a mechanical mounting system with no electrical components, so battery disconnection is not required.
The manual does not explicitly state whether step boards must be removed before bracket installation. Step 7 instructs to install step boards after the brackets are mounted and torqued. Consult the step board instructions or your installer to determine the optimal installation sequence.
1. Read instructions and verify all parts are present. 2. Follow bracket package instructions to mount brackets to vehicle. 3. Attach step pads to step plates: drill five 1/8" holes using the pad as a guide, then attach with five #8-18 x 1/2" TEK screws. Mount box step pad first, approximately 1/2" from the end cap, then mount middle step pad. 4. Install square head bolts into slots in bottom of step plates. 5. Install end caps and tighten nuts to 5 lb-ft. 6. Position step on brackets so square head screws are in bracket slots and step is centered front to rear. Install 5/16" serrated flange nuts and tighten to 19 lb-ft.
1. Read instructions and verify all parts are present. 2. Pre-assemble front bracket (Items #2, #4) on left side using three 3/8"-16 x 1.0" screws, 3/8" flat washers, and 3/8" flange nuts, torqued to 19 lb-ft. For 1500 pickups, attach small 90° bracket (Item #14). 3. Pre-assemble load reaction studs with rubber cushion washers and serrated flange nuts. 4. Attach stud assemblies to mounting brackets. 5. Remove factory front, center, and rear body mount bolts. Install front bracket (finger tight), center bracket (finger tight), rear bracket (finger tight), and rear outboard bracket to rear inboard bracket using three 3/8"-16 x 1.0" screws, washers, and nuts, torqued to 19 lb-ft. 6. Attach spring hanger mounting brackets. 7. Install step boards per their instructions. 8. Position load reaction bolt assembly so rubber cushion is snug against frame. Tighten 3/8" flange nuts to 19 lb-ft. 9. Repeat for right side.
On the short threaded end of the load reaction stud (Item #12), install a 3/8" serrated flange nut (Item #11) backwards to the bottom of the thread. Then install a 3/8" flat washer (Item #19) and rubber cushion washer (Item #10) tight against the serrated flange nut. The end of the stud must be recessed in the rubber washer approximately 3/16". On the long threaded end of the stud, install a 3/8" serrated flange nut (Item #11) backwards to near the bottom of the threads.
Loosen the spring hanger bolt just enough to slide the inboard spring hanger mounting bracket (Item #16) up behind the bolt flange. Position it behind the flange with the channel open to the outboard side. Using a 3/8"-16 bolt, 3/8" washer, 1/2" washer, and 3/8" lock nut (Items #19-21), install the outboard spring hanger mounting bracket (Item #17) so its inboard vertical portion fits inside the channel of the inboard bracket. Leave fasteners finger tight at this time. After the load reaction bolt assembly is positioned and tightened, the spring hanger bolts will be fully tightened.
Use the Step Pad Location Guide on Sheet #2 of the manual. The guide provides suggested pad positions (Pad A and Pad B distances from the front) for specific vehicles including Silverado/Sierra (double, extended, and crew cabs), Chevrolet Express/GMC Savana vans, RAM quad/crew/mega cabs, and Ford F150/Super Duty models. Note: these locations are suggestions only and may be placed at the purchaser's discretion.
Yes. You must drill five 1/8" holes through the step plate using the step pad as a guide. The step pad is then attached with five #8-18 x 1/2" TEK screws (Item #6). This drilling is required for each step pad.
No. The 571747 is a no-drill application. It uses existing factory body mount bolt holes and requires no drilling, cutting, grinding, welding, or permanent modifications to the vehicle.
The end cap nuts (Item #3) must be tightened to 5 lb-ft.
The 5/16" serrated flange nuts (Item #5) on the square head screws (Item #4) must be tightened to 19 lb-ft.
The three 3/8"-16 x 1.0" screws, 3/8" flat washers, and 3/8" flange nuts used to assemble the front bracket (Items #13, #19, #11) must be torqued to 19 lb-ft.
The three 3/8"-16 x 1.0" screws, 3/8" flat washers, and 3/8" flange nuts (Items #13, #19, #11) used to attach the rear outboard mounting bracket (Item #7) to the rear inboard mounting bracket (Item #9) must be torqued to 19 lb-ft.
The 3/8" serrated flange nuts on either side of the load reaction stud assembly must be tightened to 19 lb-ft after the rubber cushion is positioned snug against the frame side.
The O-MEGA II step is available in five lengths: 95.0", 99.0", 105.0", 111.0", and 122.0". Each length is available in silver or black aluminum. The step is 6" oval in profile.
You must drill five 1/8" holes through the step plate for each step pad. Use the step pad as a guide to locate the holes.
Due to excessive thread locker in the body mount bolt area on 2010+ GM Silverado/Sierra vehicles, use caution when removing the body mount bolts. The thread locker may make removal difficult.
The rubber cushion washer (Item #10) is installed on the short threaded end of the load reaction stud and must be recessed approximately 3/16" into the stud end. It provides a cushion between the stud assembly and the vehicle frame to absorb shock and vibration. The rubber washer must be positioned snug against the frame side before final tightening.
The mounting brackets must not touch the inside wall of the body mount housing. Ensure proper clearance during installation.
After installation, verify that the mounting brackets do not touch the inside wall of the body mount housing. Torque the body mount fasteners to manufacturer specifications.
