AEV Conversions’ new Geometry Correction Front Control Arm Brackets for JKs

New Geometry Correction Front Control Arm Brackets for JK – Want to Increase Ride Quality, Improve Braking and Eliminate Cam Bolts?

AEV is proud to offer the single biggest improvement to our JK Suspension since it was released. These new Front Control Arm Brackets are a win-win in terms of performance.

These new brackets will:
• Improve front impact ride quality (expansion joints, ledges)
• Increase Anti-Dive for improved braking performance
• Decrease the operating angle range of the front driveshaft
• Eliminate the need for adjustable control arms or cam bolts for caster correction

Improve front impact ride quality (expansion joints, ledges) – By reducing the operating angle of the front control arms, the suspension is allowed to work in a more natural state.  This means that when hitting a bump, the force applied to the control arms is directed up into the springs instead of back directly into the frame. In effect an AEV 3.5” lifted JK “thinks” its lifted only 1.25”.

Change the instant center to increase Anti-Dive for improved braking performance – By increasing the anti-dive geometry of the suspension, you’ll notice the front of the vehicle will barely drop under hard braking when the drop brackets are utilized. They also increase force on the front wheels, increasing traction for better straight line braking.  Further, they reduce the shifting weight and inertia under braking in curves, so handling is greatly improved.

Decrease the operating angle range of the front driveshaft – This one is often overlooked.  Aftermarket double cardan joints do not have the torque rating (1850lb/ft for the 1310 double cardan, 2150 lb/ft for the OE CV Joint) and they can’t run as smoothly, so it’s advantageous for most JKs to keep the stock CV units. The Front Control Arm Brackets rotate the pinion up as the axle drops to eliminate torn boots on the CV for long life in a lifted application.

Eliminate the need for adjustable control arms or cam bolts for caster correction – We’ve been touting the benefits of using the stock control arms for a long time because of the quality of the pre-loaded rubber OE Bushings that the factory uses, and because that quality has yet to be rivaled in any aftermarket bushing. These new brackets allow for the proper caster ranges to be achieved without the need for custom control arms.

The new Geometry Correction Front Control Arm Brackets are now standard in all AEV JK Nth Degree Suspensions and are available as PN Nth20410AA to upgrade all older AEV Suspensions. They can also be used on other manufacturer’s kits, however the springs must fall into an acceptable height range for the correct caster to be achieved. Please contact the AEV Tech Dept for more details.

    I installed this on a friends JK and they work great!

  3. [...] In addition to adjustable control arms, you also can use the AEV control arm drop brackets. These brackets remount your stock arms at different angles. IMO, PROS: cheaper than control arms (US$99 vs US$300+) addresses camber issue ("flightly" feel) caused by bigger lifts increases anti-dive, which helps with braking performance helps ride-quality by directing more of the force from impacts (bumps, etc) into shocks vs. the frame CONS: leaves your front control arms mounted about an inch lower than the stock position designed for 3.5"/4.5" lifts, not adjustable if you decide to run a lift that's bigger/smaller There's some more detailed info over at http://jeepin.com/news/aev_brkts [...]

    This site is great. This is going to help us immensely, we do repairs for companies making jeep tours, and Wrestling with Cam bolts adds so much wrenchtime. Will be recommending this.
