Why pay hundreds more for less??? Top 10 reasons why you should choose RPG over the others!

  • • Over 1,000,000 miles of collective abuse
  • • 3 times thicker than the stock frame
  • • Only production kit to offer actual Baja Winning Fox 2.5″ airbumps
  • • Strengthens whole rear frame, not just the weak sections
  • • Big enough and Strong enough to run 4″ long airbumps to increase payloads and towing
  • • 100% Lifetime warranty on your frame support
  • • Able to run very little air pressure for smooth and controlled ride
  • • Double cross bolt design to eliminate inward frame movement
  • • Doesn’t interfere with aftermarket exhaust options
  • • No gimmicks, just proven results with the offroad miles to prove it

Now for the long story of why RPG over the others:

The RPG system is nearly 4 times the size of other kits out there today.  The frame support is over 3 times thicker than the stock frame, and transfers the energy to a much larger cross section of the frame, and not just the inner weak part that has already proven itself prone to fail.  Unlike other systems that are out there, we also intentionally didn’t enclose the whole frame rail.  We left the inner rail open with the theory that in case of a rear-end collision, the frame still has a path of least resistance to follow.  Another major benefit of going with the RPG Stage 2, 3 or 4 system is the fact we use a full size 2.5” bump stop vs. a 2.0” bump stop that are typically only found in light buggies and mid sized trucks on the racing circuits.

The reasons why you want to run a 2.5” vs. a 2.0” on your Raptor is the following,

A 2.5” bump stop has nearly 100% more piston surface than a 2.0 Airbump, plus has far greater amounts of fluid in the bump stop body itself to help with cooling the bump. This means you can run much less valving, much less nitrogen pressure and a much shorter shaft than a 2.0” inch like found on our competitors kits.  The Fox 2.5” bump stop only requires 2.5” of shaft travel vs. 3.75-4” of shaft travel with a 2.0”.  This results in a bump stop that sits further away from the axle. With the RPG kit you won’t be hitting the bumps around town on every dip, pothole and speed bump, and most importantly, your bump stop wont be the one controlling the ride, the shock will.  The only time a bump stop should be felt is in the last 15-20% of your full bottom out travel.  It should only be a last line of defense, not a ride characteristic tool.  The Raptor is a 6000lbs truck at a minimum, simply put, a 2.0” bump has to nearly max out it’s workable valving stack plus it’s nitrogen psi limits to control the momentum of our trucks on full bump travel. Our rebound valving is setup so it doesn’t interfere with the ride, and comes out fast as opposed to slowly like you will find on our competitors kits.  A fast rebound setup will prevent double bumping in whoop sections and allows for the bump to keep up with the whole suspension.  With our kit, you only need to run 90psi for both on road and offroad. There is no need to ever adjust it from there and it offers displays very little heat buildup which results in a much longer life span.

The RPG Off-Road ’10-14 Raptor Stage 2 Rear Suspension Kit offers a lifetime warranty for it’s original owner and for over two years now has been the most tested, most abused and best selling kit on the market with thus far (knock on wood) zero warranty returns.  We have the video plastered all over the website to prove that the RPG kit paired with a Fox Racing Shox bump stop is second to none. Pair with Deaver Leaf Springs for even better performance.

    Thank You Team RPG,
    I purchased the Stage 2 Rear Suspension kit for my 2011 Raptor with the extra 4″ bump stop kit back in January 2018 to tow an Attitude toy hauler. The RPG kit improved the ride and control tremendously. For me it was a great investment in safety as the Raptor rides nearly level and handles much better with the 4″ bump stops installed, especially at freeway speeds and off-road getting to a camp site over rough terrain. Awesome product !!!
    When finances permit, I’ll be back for the springs and shocks to finish out the Stage 4.
    Extra thanks goes out to Andrew for helping resolve a parts hiccup and getting me back on the road in time for my long journey up north to pick up the Attitude. Awesome customer service !!!

    Night and day difference.

    Bought with king 2.5s and run absolutely perfect. rear end when it comes down is incredibly smooth. Only con is install. If you are not mechanically inclined i would not recommend this install. Amazing product one of the best mods if you want to run your Raptor in the dirt and not to Starbucks lol.
