JK 4 Door "Rash Guards" for GR Rocker Guards

1 review Write a Review

GenRight Rash Guard caps the high impact area of the aluminum rocker guard


This is the "Rash Guard" for the GenRight 4 door Aluminum Rocker Guards.

It is the answer for the weight conscious Jeep owner who wants lightweight but off-road capability!

It is a formed steel "cap" to protect the high contact area of the rocker guard when off road.

Since steel has a higher surface hardness, it allows your vehicle to slide along trail obstacles with little or no damage.

This is a great upgrade for anyone looking for a "functional" slider on their JK along with our lightweight aluminum rockers.


  • Fits the GenRight RCG-8104 Aluminum rockers for the 4 door JK like a glove.
  • Laser cut and CNC formed from high strength 3/16" thick cold rolled steel.
  • Wraps around to protect the high contact area on the Rocker from damage.
  • Maintains high ground clearance.
  • Design ties into existing bolts on top portion of the rocker guard.  
  • Bottom edge used flat head stainless bolts to attach the rash guard to the rocker.
  • Sold in pairs (as a kit).
  • Includes all necessary flush mount Stainless Steel hardware.
  • Aluminum color is from Zinc plating for corrosion protection (no painting required).
  • Made in USA!



  • Installation requires removal of the Rocker Guards.
  • To mount this product it requires drilling four 1/4" diameter holes per side in the GenRight aluminum rocker to secure the lower edge of the Rash Guard.
  • Also available for the 2 door JK model also (RCG-8202).
  • This product can be painted or powder coated directly over the zinc plated finish.
  • We also offer Rash Guards for the Aluminum Front (FBB-8224) and Rear Bumpers (RBB-8224 & RBB-8225) too.

    Super easy installation and provides extra strength just where you need it. I love that it is zinc plated and ready to go with no extra painting or coating required. Awesome product!
