Black powder coat steel; Ford F-150 SuperCrew, 5.5-ft bed.
Identify TrailFX 5-Inch Wheel-to-Wheel Step Bars by MPN
An unboxed set of TrailFX step bars can be difficult to identify from its black or polished surface alone. Part numbers A7051, A7058, A7062 and A7083 describe different Ford and Ram cab/bed installations; their B and S suffixes distinguish the finish and construction within each family.
Identify bars by exact part number
These are four distinct mounting families. The suffix B identifies the black steel bars and S the polished stainless version within each listed family. Fitment is not established by the suffix alone.
| Manufacturer part | Truck family | Bed length | Finish | Construction |
|---|---|---|---|---|
| A7051B | Ford F-150 SuperCrew, 5.5-ft bed | 5.5 ft | Black powder coat | Steel |
| A7051S | Ford F-150 SuperCrew, 5.5-ft bed | 5.5 ft | Polished | Stainless steel |
| A7058B | Ram 1500 / 2500 / 3500 Crew Cab | 6.5 ft | Black powder coat | Steel |
| A7058S | Ram 1500 / 2500 / 3500 Crew Cab | 6.5 ft | Polished | Stainless steel |
| A7062B | Ram 1500 / 2500 / 3500 Crew Cab | 8 ft | Black powder coat | Steel |
| A7062S | Ram 1500 / 2500 / 3500 Crew Cab | 8 ft | Polished | Stainless steel |
| A7083B | Ram 1500, newer-body Crew Cab | Confirm exact bed | Black powder coat | Steel |
| A7083S | Ram 1500, newer-body Crew Cab | Confirm exact bed | Polished | Stainless steel |
TrailFX family notes: A7051 is the F-150 SuperCrew short-bed application; A7058 is the Ram Crew standard bed; A7062 is the long-bed Ram Crew; A7083 belongs to the newer Ram 1500 body. The B/S suffix does not change the required cab and bed measurement.
Installation requirements differ. These are model-specific rocker-panel kits with mounting brackets. Some applications may need drilling; follow the current instructions supplied for the exact vehicle and part number. Do not assume the newer-body Ram 1500 and older Ram 1500 Classic use the same brackets.
What to check on the truck or removed bars
- Identify the cab: the Ford example is an F-150 SuperCrew with a 5.5-foot bed. Ram examples require the listed Crew Cab layout.
- Measure the bed: A7058 and A7062 serve different Ram bed lengths, 6.5 versus 8 feet, even though both are 5-inch oval step bars.
- Check the truck generation: A7083 serves the newer-body Ram 1500; do not assume the same mounting as an older-body Ram 1500 or Classic.
- Choose material: B denotes black powder-coated steel, while S denotes polished stainless steel; brackets are vehicle-specific.
- Check your installation: factory rocker-panel attachment points, underbody equipment and the current kit instructions determine whether drilling is needed.
