We'll start by quoting from Luverne's product page which sums it up accurately:
"Stop messing around and start getting the job done with LUVERNE Grip Step™ 7" running boards. These roughneck steps feature a unique expanded metal tread pattern for superior traction and a 7" x 2 1/2" rectangular design for reliable footing. They are built from aluminum alloy for exceptional, rust-free strength, and they are simple to install using high-strength vehicle-specific brackets.
As always, Grip Steps™ are made right here in the USA for quality you can trust and footing you that won't let you down."
We installed the Luverne side Grip Steps as well as the rear step. All components were labeled accurately and the instructions included descent diagrams. Once we had installed the shortest step, the driver's side, we learned the sequence and were able to complete the large passenger side full step as well as the rear step in a fifth the time as the first step took.
Luverne is known for their quality products, and these steps are no exception. The all-aluminum steps are super light, a lot of the hardware was stainless steel and the brackets were made of thick metal -- probably 3/8" steel.
We had to modify the installation a bit as some of the undercarriage of our van did not match that of the instructions but it was just a matter of purchasing some additional large self-tapping bolts.
The steps are functional and we like the look too.
