Part # 30120  |  Made in the USA  |  Lifetime warranty for the original owner (relocation brackets)

Complete launch upgrade  |  Includes Part #23865 + Part #23885  |  Matching powder coat finish  |  Direct bolt-on

Wheel hop, axle wrap, and soft factory rear suspension holding back your launches? The Stage 1 Launch Kit pairs two proven J&M components that work together: stronger rear lower control arms and adjustable relocation brackets that improve instant center, anti-squat, and rear-end stability on 2005-2014 Mustang S197 models.

This kit includes a matched set of Part #23865 boxed street/drag rear lower control arms and Part #23885 bolt-in lower control arm relocation brackets. Both ship in the same powder coat color (black or red) so you get a coordinated, ready-to-install rear suspension upgrade instead of buying pieces separately.

What's Included

• Part #23865 - Boxed Street/Drag Rear Lower Control Arms - Stronger boxed arms with greaseable fluted elastomer bushings to reduce control arm and bushing flex, improve traction, and cut wheel hop versus stock stamped arms.
• Part #23885 - Bolt-In Lower Control Arm Relocation Brackets - CNC laser-cut 3/16" cold-rolled steel brackets with three mounting positions to increase anti-squat and fine-tune rear geometry for better launches and handling on stock or lowered cars.

Why Run Them Together

• Less wheel hop and axle wrap - Stiffer arms and relocated mounting points keep the rear end planted when you load the suspension on launch.
• Improved anti-squat - Three-position bracket adjustability (2", 2-3/4", and 3-1/2") lets you dial in rear geometry for straighter, more consistent passes.
• Sharper handling on lowered cars - Helps recover control arm angles and reduce roll understeer after lowering.
• Complete matched kit - Arms and brackets are engineered to work together and finish together in your choice of black or red powder coat.
