MaxTrac K330823S GM SUV 2"/3" Adjustable Lowering Strut Kit

Dial In a Lower Stance with Front & Rear Adjustable Struts

Lower your 2021–2026 GM full-size SUV with the MaxTrac K330823S Adjustable Lowering Strut Kit. Designed for compatible models without MagneRide or Adaptive Ride Control, this package combines two 221903 front lowering struts and two 230803 rear lowering struts for a matched four-corner suspension setup.
Configured for up to a 2" front and 3" rear drop, the K330823S delivers a substantially lower stance without relying on lowering coils. The adjustable-height strut design also provides flexibility when setting up the vehicle, but MaxTrac notes that the more aggressive 2"-3" settings affect both alignment and ride firmness.

Key Features

2" Front / 3" Rear Lowering

Provides a 2" front and 3" rear drop configuration for a noticeably lower, more aggressive SUV stance.

Complete Front & Rear Strut Package

Includes four lowering struts covering both axles, giving you a matched suspension package instead of separate front and rear components.

221903 Front Lowering Struts

Two MaxTrac 221903 adjustable front struts provide the front lowering configuration.

230803 Rear Lowering Struts

Two MaxTrac 230803 adjustable rear struts complete the rear suspension setup.

Adjustable Height Design

The lowering struts provide adjustable ride-height capability, allowing the suspension height to be configured for the desired application.

No Lowering Coils Required

Ride-height adjustment is handled through the strut package, making this a strut-based lowering solution rather than a replacement coil spring kit.

Important Notes

Provides a 2" front / 3" rear lowering configuration.
When struts are set at 2"-3" of drop, alignment will be outside factory specification without aftermarket upper control arms.
MaxTrac Part #351900 upper control arms are required for proper alignment correction at these aggressive drop settings. MaxTrac lists availability as ETA Summer 2026.
Lowering struts configured at 2" or 3" of drop will produce a stiffer ride than the same struts set at stock height or a 1" drop.
Does not fit MagneRide or Adaptive Ride Control models.
Does not fit AT4 models.
MaxTrac does not recommend wheels wider than 9" or wheels with less than 4.5" backspacing. Using wheels outside these specifications may void applicable manufacturer warranties.

Why Choose MaxTrac K330823S?

The MaxTrac K330823S offers a four-corner approach to lowering compatible late-model GM SUVs. Instead of mixing lowering springs with separate dampers, the kit packages 221903 front and 230803 rear adjustable lowering struts into one coordinated system.
The adjustable design also gives builders flexibility when selecting ride height. For aggressive 2"-3" drop settings, however, MaxTrac specifically calls for 351900 aftermarket upper control arms to restore proper alignment and warns that ride quality will become firmer.
