UMI Performance 3622-R Rear Extended Lower Trailing Arm | DOM Steel | Red Powder Coat

The UMI Performance 3622-R is an extended-length rear lower trailing arm engineered to optimize wheelbase geometry and improve wheel-in-well appearance. Built with precision manufacturing and premium materials, this arm is a direct upgrade over weak factory stamped steel components.

Key Features:

• +5/8" Extended Length — Optimizes wheelbase to improve the visual positioning of the wheel within the wheel opening
• 0.120" Wall Thickness Rectangular Mild Steel Tubing — Heavy-duty boxed construction provides superior strength and rigidity over OEM arms
• MIG Welded DOM Steel Bushing Holders — Drawn Over Mandrel steel ensures precise bushing fitment and long-term durability
• CNC Machined for Precision Tolerances — Ensures accurate fitment and consistent geometry across every unit
• Modern Formulation Greaseable Polyurethane Bushings — High-quality poly bushings reduce slop and can be re-greased for extended service life
• UMI Red Powder Coat Finish — Durable, long-lasting finish resists chipping, rust, and corrosion for a clean underhood appearance

UMI recommends pairing these extended lower trailing arms with compatible extended-length upper arms such as the UMI 3619, 3620, or 3624 for optimal suspension geometry correction and performance.
