TRZ Motorsports Housing Side 4-Link Bracket Kit - Mild Steel - 3" Axle Tube Diameter - 650-220
Track-Proven Mild Steel 4-Link Bracket Kit for 3" Axle Tubes
The TRZ Motorsports Housing Side 4-Link Bracket Kit (Part #650-220) is built from years of data gathered from top-tier X275 and No Time (N/T) race programs. Engineered for strength, adjustability, and big-power repeatability, this mild-steel bracket kit fits 3" axle tubes and provides a wide range of tuning options for small-tire and big-tire applications alike.
The brackets feature 1/4" thick main plates, reinforced with 1/4" doublers for added rigidity. TRZ incorporates multiple critical features, including an upper 1" ID mount support hole, 1.5" ID lower cross support hole, built-in Pro-Jack mount, anti-roll bar mounting locations (three positions), and adjustable shock mounting in 5/8" increments.
Every kit includes billet aluminum double-shear shock mounts, eight doubler plates, support strips, and 2.25" diameter center tube supports - giving builders everything needed for a strong, track-tested rear suspension foundation. Designed for 1/2" ID x 3/4" wide rod-ends. Hardware is optional and sold separately.
Optional upgrades include 1" offset billet shock mounts and 2.5" dropped billet shock mounts to fine-tune shock geometry. AN or NAS hardware kits are available for the rod-end mounts.
