TRZ Motorsports Frame Side 4-Link Bracket Kit - Chrome Moly - 650-260
4130 Chrome-Moly Frame-Side 4-Link Bracket Kit for Serious Drag Race Applications
The TRZ Motorsports Frame Side 4-Link Bracket Kit - Chrome Moly (Part #650-260) is built for high-horsepower drag race cars needing maximum strength, rigidity, and precise suspension tuning. Developed using years of real-world performance data from leading X275 and no-time programs, these brackets offer exceptional adjustability with 5/8? hole spacing - ideal for fine suspension control.
Each bracket is constructed from 1/4? thick 4130 chromoly for superior durability while maintaining a lightweight profile. The kit includes matching 1/4? thick upper and lower doubler plates that reinforce the mounting area and improve long-term chassis stability. A split double-hole layout provides expanded tuning capability for both small-tire and big-tire combinations.
Integrated features include a 1? ID upper mount support hole, 1.25? lower support hole, and a 1-1/4? Pro-Jack mount, making the system compatible with advanced rear-end setups. Designed for use with 1/2? ID × 3/4? wide rod-ends, the system does not include hardware - but AN or NAS kits are available as options.
