Rubicon Express Super Flex Bolt Question

[tread684]

I've tried scouring the the specs but I can't locate the the bolt size and threading for the RE3715.

That's the adjustable lower control arm. I'm looking for the frame to control arm side.

Seems like it might be metric and the nut looks special. Nothing in the nut bin works.

Much appreciated!

They should have come with 9/16-18 bolts and lock nuts. RE does indicate that the factory (non cam bolts) M14 bolts can be reused. If there is any question as to what they are I would recommend replacing them with 9/16 grade 8 bolts. I wouldn't want my control arms held on by some unknown bolts.

The only broken control arm bolt I have ever had was from RE. It snapped on the trail which allowed the axle to twist causing the track bar axle and opposite control arm brackets to tear out of their welds, a broken rear driveshaft u-joint, and a broken pinion yoke. It was a several hour repair in >100 degree desert heat.

This is the track bar repair. All from a shitty RE control arm bolt. The trail was Pumpkin Eater in SoCal.

I've wheeled a 3.5" super flex kit since 2003 and haven't had any issues.

Right now I am wrapping up a full restoration of the jeep and cross threaded the described bolt. Looking to get a replacement from mc master. Two years ago I replaced the shocks and springs, the powder coating on the spring seemed to fail prematurely, RE express shipped me out a full set of springs. They stand behind their product even though they've been acquired by a larger company.

Just confirmed with RE 9/16 x 12 thread. overall length is 4 1/2"

I got a loose (or it just fly away when breaking) control arm bolt.. I was around 30 miles per hour and up in the Sierra Madre between Sonora and Chihuahua,it was dark and hundreds of kilometers from civilization, but one of the guys I was wheeling with carried a spare... is now one of my must-to-have inside of my jeep even tho I have grade 5 bolts in all my arms... it was not RE bolt but definitely was not a good quality one... at that time I didn't consider the bolt grades to be critical.... its different now as you may bet...
