 Performance + durability of a race part.
Manners + longevity of a stock part.
The best of both worlds.

Over the past 10+ years of building and breaking 4Runners, we have experienced a lot of different rear arm kits. There were lots of options on the market, but there just wasn't anything that checked off all the boxes. So we decided to build our own set of arms, using overkill steel tube, top quality machining, and the industry's gold-standard Johnny Joints®.

Description:

Thick-walled DOM steel:

  • No more breaking and bending rear arms! 1.625in tube lowers, 1in tube uppers for the best balance between strength and clearance throughout travel.
  • Wrench flats for easy adjustment and torquing of the lock nuts.
  • Powdercoated textured black with etched-in OPT logo.

Double-adjustable design:

  • Correct your pinion angle to prevent premature u-joint wear and vibrations (if you have a lift then this applies to you).
  • Move rear axle position for easier tire clearance (if you have 35in+ tires then this applies to you).
  • Superior to other "single-adjustable” arms: no need to uninstall anything to adjust the length. Simply loosen the jam nuts, dial in your lengths, and then tighten the jam nuts back down. Double-adjustable arms also have twice the adjustability length (3in) versus single-adjustable arms.

Johnny Joints® throughout: (valued at $66 each, or $528 for a full set!)

  • Custom machined for our trucks specifically, for perfect fitment with stock mounts and hardware. To our knowledge, these are the first and only set of rear uppers and lowers that utilize nothing but Johnny Joints! If you aren't familiar with their reputation, click here (short version: they're the best).
  • Sealed, greasable flex joints with ultra-low maintenance and none of the clanking, moaning, or squeaking of polyurethane, heims, and other flex joints. (our V1 prototypes have never been greased or serviced, for testing purposes. Spoiler alert, they're still flawless and silent). They're serviceable and easily rebuildable, so it's money saved in the long run.
  • More articulation than stock, polyurethane, heims, and other flex joints. Johnny Joints have an impressive 34-42 degrees of articulation depending on the joint (other brands claim up to 33).

Pricing:

  • Pair of Upper Control Arms: $399
  • Pair of Lower Control Arms: $499
  • Full Kit, Uppers and Lowers: $869 ($29 bundle discount)

FAQs:

Without a poly/rubber bushing at one end, shouldn't I worry about damage to my truck's lower link mounts?

No! We designed the lower arms to include one narrow joint (for articulation) and one standard joint (for cushioning). The standard model JJs have as much built-in cushion as a conventional poly bushing, due to the 2-piece construction of their proprietary urethane bushings. Regardless of your setup, we recommend installing a Lower Link Reinforcement and Upper Link Reinforcement kit on any trail rig, as the potential for mount damage increases the more you upgrade the truck and push the limits.

What should I use to grease the joints?

Any standard Moly Grease will do just fine, but Rock Jock 4x4 has a proprietary Moly Grease that is available in our Rebuild Kit menu.

Is hardware included?

No, we had these Johnny Joints custom built so they are specifically sized for our factory bolts! This helps keep your cost lower and makes installation easier.

 Why no adjustable panhard bar?

First and foremost, we recommend a Panhard Correction Kit before upgrading your panhard bar. Adjustable bars are proven to be less effective than a PCK, and more expensive at that. The PCK will solve both the axle recentering issue AND the geometry issue, unlike an adjustable bar by itself. Per eimkeith: "The Panhard Correction Kit returns the panhard bar to horizontal (per original design), eliminates the need for an aftermarket adjustable panhard bar to recenter the axle, and in most cases (up to 4 inches of lift) raises the roll center for improved handling..."

If you are in need of an adjustable panhard bar, check out the Double Adjustable Panhard Bar from KDK Fab.

Winner of the aggressive chew competition
Color: No Stuffing Blue Eel
I bought several toys for an insane Jack Russell and this is the unlikely winner. It is a softer toy, but it is stitched together nicely and there are various components that distract the dog and keep him busy. First, it can be rolled up and stuck with small but strong Velcro patches, so it’s not just a sitting duck, the dog has to figure out how to unroll it which is fun. Next there are five little pockets on one side that you can put treats inside, which draw attention to the toy and give him another task. He did partially rip some of the flaps on the pockets in his zeal to get the treats. Then there is the squeaker, which he dispatched of in like 4 seconds (somehow without ripping the fabric(?)), then there are all sorts of crinkles and textures on both sides. All of this and the good stitching make it a toy he wants to play with but that he doesn’t annihilate in one day. The hard plastic toys are also good but I feel like I need to watch him carefully for fear that a sharp chunk will come off. The medium chew toys are cool but he’s just not into them. So this wins!

My dogs favorite toy!
Color: Blue & Yellow Eel Bundle
This is my Jack Chi and Yorkies favorite toys (it helps when they get 5 mini milk bones). It is a tough toy, but not impervious to a Jack Chi determination to remove all squeekiees! Squeekie or not, it's still their favorite toy for tug-a-war.

Fun Toy
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
My dog loves this toy. It has 2 squeaky & also has crinkly sound along with the slots for treats. However it is not very durable. The treat slots were pretty much destroyed with the first use. I'm still giving it a 4 star because it is so fun & entertaining for my GSD.

Kept puppy interested!... Till she chewed it apart in 5 minutes
Color: No Stuffing Blue Eel, Color: No Stuffing Blue Eel
I'll start off by saying this is a really unique toy. You really can hide treats in the pocket and the velcro is strong enough to roll it up that it won't come undone easily. The different textures and sounds interest my puppy! And she LOVES it! But it didn't last long with her. She LOVES rope toys and ripping them apart and eating it. I literally had just given it to her and not even a minute later (not joking), she had torn off a row of the rope-like part. 5 minutes later, the tail is already in shambles lol So long story short, great and interesting toy to keep the doggy from being bored. Maybe not so great for aggressive chewers/rippers in the long term. More than likely will be torn to shreds by the end of the day.

Great quality, fun design.
Color: No Stuffing Blue Eel
Wonderfully durable.. We have a 3 y/o australian kelpey and a 2 y/o pitty.. both are incredibly playful and tear up toys like nobody's business. A lot of the time under a day.. We're on day three with this eel, they love it and its holding firm (no tears or missing pieces). Squeakers are their favorite and these ones are perfect ( prominent but not too loud)
