"Fast delivery. Good price, Easy installation. These look great on the truck. Wife loves them but wonders why I waited so long to get them." —Carol J from Arvada, CO bought a Steelcraft 3" Round Step Nerf Bars for a 1999 GMC Sierra, Extended cab.
"The overall appearance is very good for my truck. I have a 5" lift and these help with entering and exiting the vehicle. The instructions for this product are weak, at best. I had to go online to the company website to obtain the correct measurements for placement of braces. The printer they used to print the instructions must have been low on toner as they were very faint. If you have a lift to raise your vehicle the installation might be easier. It took approx. 2 hours per side." —Robert R from Temple Terrace, FL bought a Go Rhino Dominator II Cab-Length Nerf Bars for a 1999 GMC Sierra, Extended cab.
"I did not realize these were Factory Seconds.
Shipment arrived without instillation instructions.

"Great looking and install couldnt of been easier. Shipping was very prompt. Completely satisfied with the purchase." —Michael G from Waynesville, MO bought a Tuff-Bar 3" Step Bars for a 1999 GMC Sierra, Extended cab.
"Great buy and very fast delivery ... I had the chrome version on for over 11 years on my 99 GMC ... I ordered the black version this time ... I was able to keep the same mounts so it was just a matter of removing 4 bolts. I had to use air wrench to do this job since the bolts were rusted on pretty good. The older mounts looked to be built better so I ended up leaving them on. My truck is a 3 door but there was no option to pick 3 or 4 door ... but its not a big deal ... just makes cleaning the roof of truck easer by having something to stand on back there.
Look great and built like a rock. Easy install." —Timothy H from Colfax, WI bought a Westin 3" Signature Series Nerf Bars for a 1999 GMC Sierra, 1500, extended cab.
