Description
The Mopar Front Lower Control Arm for the JL Wrangler is a replacement for the extended, redesigned control arm that is included with the Mopar 2" Performance Suspension. Control arms are integral to the Jeep suspension and with the proper length control arms, your front axle maintains its position under heavy abuse while on the road and on the trail. Engineered to maintain the wheel's caster, with the wrong control arms you may notice shorter tire tread-life as well as wheel and tire oscillation at higher speeds. Wrangler JL owners with stock suspensions have benefit from the redesign, choosing to swap OE arms with these longer arms for better control.

Hello Quadratec question on Mopar control arm i have 3 inch lift kit does Mopar control arm will benefit me for geometry issue? have a 2021 Jeep wrangler JL unlimited rubicon 4door with 4cyc engine thanks.

Quick answer: No, these won't work for your lift.
Understanding why and what you do need:
When lifting a 2021 Jeep Wrangler JL Rubicon to 3 inches or higher, the factory-length Mopar control arms (even the extended ones from the Mopar 2" lift) are not enough to fully correct your suspension geometry.
The Mopar Front Lower Control Arms (found in the Mopar 2" lift kit) are fixed-length and slightly longer than stock. While they are a great budget fix for a 2" to 2.5" lift to restore caster, using them on a 3" lift often leaves your caster angle too low, which can cause "flighty" steering or a wandering feel on the highway.
Since you are at the 3-inch mark, a set of Adjustable Front Lower Control Arms is the most important upgrade. If you want the best possible geometry, a full set of 8 arms (uppers and lowers) is ideal, but the front lowers are the "must-have" for safety and drivability.

This is stated for a 2" lift. Is it good for a 2.5" or 3.5" lift? Thanks

With that size lift, a control arm geometry bracket would be suggested or using an adjustable control arm that is more appropriate for the 2-6" lift range. Yes, the control arm will still work, but your handling and geometry may not be at it's best if used with larger lifts. Thanks for your inquiry.

I used your system to see if it fits 2023 gladiator spot s but it says it does not fit. I am installing a BDS 2 inch lift kit and these are supposed to be the arms in the gladiator mopar 2 inch lift as well. Will this fit the gladiator models with 2 inches of lift?

These are not compatible with Gladiator JT models. Sorry for the inconvenience.
