TRZ Motorsports Housing Side 4-Link Bracket Kit - Mild Steel - 3.25" Axle Tube Diameter - 650-230
Track-Tested Mild Steel 4-Link Brackets for 3.25" Axle Tubes
The TRZ Motorsports Housing Side 4-Link Bracket Kit (Part #650-230) is built for serious racers who demand precision, durability, and adjustability in their rear suspension setup. Developed from extensive testing in top-running X275 and No Time (N/T) programs, this mild steel bracket system fits 3.25" axle tubes and provides the adjustability needed to dial in both small-tire and big-tire combinations.
The mild steel version uses 3/4" adjustment spacing and features 1/4" thick mounting brackets paired with 1/4" thick doublers for increased strength. TRZ integrates multiple key components into the bracket system, including a 1" ID upper mount support hole, 1.5" ID lower cross support hole, a built-in 1-1/4" Pro-Jack mount, three anti-roll bar mount locations, and adjustable shock mounting in 5/8" increments.
Each kit includes double-shear billet aluminum shock mounts, upper and lower doubler plates, bracket support strips, and 2.25" diameter center tube supports. Designed for 1/2" ID x 3/4" wide rod-ends, this bracket kit forms the foundation for a serious competition-grade 4-link setup.
Optional equipment includes 1" offset billet shock mounts or 2.5" dropped billet shock mounts, plus AN or NAS hardware kits for rod-end mounting.
