Rear Adjustable Control Arms (96-02 4Runner)
Performance + durability of a race part.
Manners + longevity of a stock part.
The best of both worlds.
After over a year of R&D and trail testing the v1 prototypes on Sandy, we are proud to finally release these rear control arms to the 3G4R community.
Over the past decade or so of wheeling our 3rd gen, we’ve experienced a few different brands on the market. Our adjustable arms equipped with Johnny Joints blow them away... More articulation than heims or poly, and SILENT, rebuildable, greasable, more durable, the list goes on.
The challenge we faced was building a "no compromise" set of rear arms that were better than anything else out there, while keeping build cost low enough to sell them at a similar price as the current (less ideal) products on the market.
We knew that Johnny Joints were the best in the business, and that’s what we wanted on our arms. But they are valued at $60 each (that's $480 in joints alone, between uppers and lowers). On top of that, none of them fit quite right on our trucks. So we had Johnny Joints built specifically for our 3rd Gen 4Runners, to accommodate stock mounts and hardware (perfect fitment!)... It was a challenge, but thanks to the support of the community and the amazing guys at Rock Jock 4x4, we pulled it off.
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.
- Powdercoated textured black for rust protection.
- OPT logo etched in, for fun.
- 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 (then reinstall and check, then uninstall and reinstall until it's right...) Just 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 versus single-adjustable arms.
Johnny Joints® throughout:
- 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).
Pair of Upper Control Arms: $349

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?
Adjustable panhard bars are proven to be less effective than a Panhard Correction Kit, and more expensive at that! We prefer to let people save money where they can, so for now we are not offering adjustable panhard bars. We recommend installing a PCK to solve both the axle recentering issue AND the geometry issue. 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..."
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 wide joint (for cushioning). The 'wide' 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 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 sells some on their site, or we can have some shipped to you if you'd like their specific brand. Just give us a call!
