N-FAB RKR Rails are perfect for the off-road enthusiast. They are constructed using a .120" wall and 1.75" tubular steel. Then they are treated inside and outside to resist rust and corrosion. The RKR Rails are fully welded to provide maximum strength. The RKR Rails have optional drop-down steps that are sold separately in pairs if you want a unique look while giving you a more helpful step up.


  • Patented detachable step option allows ease of access and installation
  • Direct bolt-on applications, utilizing pre-existing factory mounts
  • Mounting brackets are welded to RKR-Rails for additional strength and durability
  • Non-modular, dual-bar welded assembly with 1.75" main tube diameter
  • Standard color textured black powder coating, using N-FAB's 3-stage powder coating process


N-FAB wheel to wheel RKR Rails will install simply and easily without drilling. Each set has been custom design to bolt on to eliminate flexing. The product comes with easy to understand vehicle specific installation instructions.


5-year finish / Limited Lifetime workmanship.

Love the way they look and it fit great. Little problem with the powder coating, but you can't see it.

FedEx at it again
Ordered the rock sliders and they shipped quickly. FedEx delayed the shipment and when I received it, there were some blemishes on it from the shipping. They’re gonna get more dings and scratches from being used but it’s unfortunate they had some gouges in the powder coating. Overall easy to install and good quality.

Nice rails
Installed these on my 2016 4Runner because I wanted protection from rocks, stumps, etc. These rails are heavy duty and will protect your vehicle from the above but if you're looking for a side step or running board style, these aren't for you, those will just get beat up and bent. Also these look GREAT on my truck!
