TRZ Motorsports Housing Side 4-Link Bracket Kit - Chrome-Moly - 3.5" Axle Tube Diameter - 650-250
4130 Chrome-Moly 4-Link Bracket Kit for 3.5" Axle Tubes
The TRZ Motorsports Housing Side 4-Link Bracket Kit (Part #650-250) is engineered for hardcore drag racers who need the strength and precision of 4130 chrome-moly for extreme power levels. Developed through extensive X275 and No Time (N/T) racing, these brackets deliver exceptional durability and ultra-fine suspension adjustment capability for top-level competitive setups.
This 3.5" version uses 5/8" adjustment spacing - tighter than the mild-steel variants - providing more detailed tuning resolution for instant center and anti-squat geometry. Built using 1/4" thick chrome-moly brackets paired with 1/4" thick doublers, the system ensures maximum rigidity under high load.
TRZ integrates a full suite of performance features, 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 rod-end mounting positions, and 5/8" increment shock mounting. Each kit includes double-shear billet aluminum shock mounts, doubler plates, bracket support strips, and 2.25" center tube supports.
Designed for 1/2" ID x 3/4" wide rod-ends, the kit also supports optional upgrades such as 1" offset billet shock mounts or 2.5" dropped billet shock mounts. AN and NAS hardware kits are available separately.
