Buying the Perfect GMC Step Bumper for Your Vehicle's Needs
A step or rear step bumper is a bumper variant that you can step on like a stool or step ladder in order to have easier access of the bed or box of your GMC pickup truck from over the tailgate or the trunk and floor-mount of your GMC van. There 's no front step bumper because more often than not, the rear is where you put your cargo at. To access the roof of the front part of your vehicle, there are usually side step ladders or steps instead. It 's a bumper that can double as a one-step ladder, in short.
Different Step Bumper Materials to Choose From
When shopping for a step bumper, it 's important to take into consideration the different materials the bumper could be made of. Pick the one that makes most practical and financial sense to you.
Poly Resin Plastic:Most auto manufacturers nowadays make poly resin plastic bumpers (since it 's the most cost-effective of the bumper material options around), which means a majority of newer vehicles have stock bumper made of poly resin. However, since step bumpers require reinforced or rugged materials, some motorists might prefer sturdier, more impact-resistant step bumpers that could handle the weight of a full-grown adult and whatever he or she could carry. It 's a bumper type that can be popped out easily but cannot be sanded.
Fiberglass:As for aftermarket replacement step bumpers, they tend to be made of fiberglass. It 's a tougher material than poly resin plastic and is known to be easily reparable unlike poly resin, plus it 's every bit as strong and lightweight as some grades of aluminum. However, it 's less flexible than plastic, so it tends to crack even in low-speed collisions.
Carbon Fiber: Carbon fiber is arguably the toughest but most expensive bumper material out there. It 's also durable and lightweight, like aluminum. It also has additional benefits, like the fact that it can be painted or left unpainted and heat resistance. What 's more, the quality of the fiber varies from one maker to another so choose carefully. It 's reparable, but it should be painted in order to conceal the repair.
Metal:Originally, all bumpers (including step bumpers) only used metal. However, despite its durability and strength, it 's a heavy material that 's susceptible to corrosion (painting the bumper can only do so much before rust sets in). Meanwhile, the added weight drags the vehicle and lowers its fuel efficiency. However, as far as step bumpers are concerned, it 's a rugged choice that can support great loads.
Aluminum:Aluminum practically has the perfect combination of quality and price among the step bumper options here. While it 's not as tough as metal, aluminum is not likely to corrode. While stainless steel is also tougher and has anti-corrosive properties, aluminum is lighter. While carbon fiber is just as lightweight and even more durable, aluminum is a lot more affordable. While plastic and fiberglass is cheaper, aluminum is superior in every other way.
The Bottom Line
Your choice of step bumper should depend on how strong of a bumper is required (it should at least be able to support your weight as you step on it) and how much your budget is. There are various other options to take into consideration, like the compatibility or fitment of the step bumper and how solid its design is, but your primary concern should be the material it 's made of.
