i have a re sf kit on an 05 rubicon. the kit includes f/r re adj track bars, rear upper sdj control arms and 3.5" springs.
the first set of super ride bushings lasted three months and the second set one month. re has a problem with their super ride bushings.
the kit performs very well for a short arm kit.
i will probably end up changing out the lower control arms or cutting off the super ride end of the lowers and welding on johnny joints.
super ride joints sux. |

I got this kit not to long ago and LOVE it! flexes like a demon and i run MX6 shocks from procomp. those of you who want great road manners and the off road manners as well this is the kit for you. they say that you might need a 1 inch body to clear 35s but i do it just fine under full flex and turn. took 22 hours to install and a 5/8 drill bits are hard to find but it was worth it. |

I've read everything I could find about the RE 4.5 Superflex kit. Being that I am not a mechanic, I was quite aprehensive about tackeling the install. Now that it's over, I don't see what all the fuss was about! I'm a 41 yr old, with a bad back, and I did it with no help. If you have the proper tools, and can follow directions, you can put this kit on yourself.
The lift is even better than I expected. Once dialed in, with sye, cv ds, and all angles correct, it rides better than my TJ did stock. I'd recommend this kit to anyone who wants quality, flex, and street mannors. :) |

TJ Kit with 3.5 springs |

This is a very good kit, very nice quality, straightforward install, all the parts were there and decent instructions.
Keep in mind that although very complete you will find yourself possibly buying a few other things in addition to shocks. Depending on your vehicle you might need a new rear track bar and either weld on or bolt on rear spring relocators.
I have a high clearance (Nth Degree) center skid, so I needed both to work with my raised pinion. This was with the 3.5" springs, the 4.5's would make these parts even more necessary.
After getting it all installed, I brought it in for an alignment and all went fine, everything set at the factory specs. I have since adjusted my rear pinion a few times to eliminate vibrations- I can't imagine a kit without adjustable control arms like RE gives you- your jeep would straight up suck to drive if so.
You may hear about short arm lifts riding rough- here's my take: Your TJ with its original suspension rode rough anyway. My newly lifted Rubicon rides almost exactly the same as original. A Long Arm may make it ride better than stock, but don't let someone saying that a SA kit rides rough scare you off. Rubicon Express is great quality, and if you get a good kit, install it properly, and adjust some vibes away, you'll have a good ride. |

I must say a 5 is only for the troubles I have had. The kit works very close to a 10 for what it is. I purchased this kit approx 8 months ago and have been very happy with the performance, but I have had to replace the rear upper arm front bushings 4 times. Rubicon Express were cool enough to replace the first three but I am now on my own at twenty bucks each. The jeep is not a daily drive and has only 6K miles on it and Ive had it a year. Whats happening is the rubber bushing is splitting in half and grinding apart to the point of falling out and the control arm is just banging around the bolt that holds it on. I have never driven with anything loose and I keep it well lubed. I am really happy with the performance of the kit, but I do not want to replace bushings every other trip. I feel Rubicon Express should Johnny Joint both ends to eliminate this problem. Has anyone else had this problem? |

I have been using this lift kit for about 8 months and it performs great. My jeep driving manners got better than stock (i must say that i am using Procomp MX-6 Shocks). But I have to mention that HAD to install the SYE. The only thing I dont like is that It has developed a small noise in one of the 8 arms. |

OK this is how i put my kit together and its incredible. after owning my XJ for about week i ordered my kit. I bought the RE 4.5 inch superflex kit but i had them switch the rear which was 3.5 inch lift springs with a 1.5 inch shackle for just the 4.5 inch spring cuz i figured id want to up grade and this left me more room for that. So after finding that the stock shackle gave me hardley anyflex i put on the 1.5 inch RE shackle they accidentaly send me anyway and added 2 inch coil spacers to the front springs. now sits completely level at about 6 inches, i have no SYE, hardly any vibrations, i fit 33s beautifuly, the RE short control arms from the 4.5 inch kit did pull my front axle back a little bit but it rides and flexes awsome. i like the short arms cuz they dont get in the way like longarms do. ive rident TEllico in NC and Paragon in PA and impressed everyone with my articulation and trail ability, especialy with open differentials. |

Very solid, handles good. The 35s rubbed a bit until I put additional length bump stops in. You "will" feel road vibration that you never felt before. Must have SYE. I now can go wherever my courage will let me. |

Ive been running this for a while and It is a great kit, I would recommend it with an adjustable rear tracbar that way you dont have to mess with the brackets. But I give it 10 stars great articulation solid product. |

I've put three of these kits on mine, my nephew's, and a friends Jeep (2000, 97, and 2004 Rubi). I learned a lot in the process. You must have a SYE, and along with that you'll need to have both rear shock relocators (on the axle) and an angled rear track bar mount to deal with the rotation of the rear axle for the CV driveline. You'll need a good, and I mean Snap-On or Mac Tools, 55mm Torx driver. And last, be very careful in drilling the chassis mount end of the front trackbar. This is my only complaint on the kit, this end is very succeptable to loosening up. You'll have to check it periodically after installation. This design is very common among aftermarket trackbars. As far as function, I ramped 950 with 33" tires. I'm now running 35s and they hit the front fender just slightly under full compression, but I've got extra weight in the front. Also this lift kit runs higher than 4.5" typically, and slightly low in the front. You may need to add front spring spacers. And my last thing, it can be a bit noisy on the trail, clunk noises under max. articulation. |
