Calvert Racing Suspension Components Now Available at Summit Racing

| October 4, 2019 More

You probably know Calvert Racing best for the famous CalTracs Traction Bars, but the company also makes leaf springs, shocks, and suspension components designed to help cars hook up better and run quicker.

CalTracs Traction Bars
Slapper-style traction bars keep axle rotation in check by applying force upward on the spring, preventing spring wrap-up and maintaining the proper pinion angle. CalTracs Traction Bars work better. They bolt to the front spring eye and the bottom of the rear axle, and use axle rotation to create downward force on the front of the spring. That prevents wrap-up and maintains the proper pinion angle, but more importantly, it applies forward motion at the front spring mount. This moves the instant center of the car further forward and shifts weight from the front to the rear of the vehicle. More weight at the rear means better traction off the line and improved 60-foot times.

We also have low-profile CalTracs bars for street-driven vehicles. The bars are adjustable, but have just one height setting for extra ground clearance. Summit Racing carries CalTracs for many leaf-spring cars and light trucks including:
• 1964.5-73 Mustang
• 1960-70 Falcon
• 1967-81 Camaro and Firebird
• 1962-77 Nova
• 1955-57 Chevy passenger car
• 1962-78 Mopar B-body
• 1982-2004 GM S-Series truck
• 1999-2017 GM Silverado/Sierra 1500
• 1999-2017 Ford F-150

Split-Mono Leaf Springs
Designed for use with CalTracs Traction Bars, the Split-Mono Leaf Springs are much lighter than factory multileaf springs, reducing your vehicle’s unsprung weight. The split design features a heavier front portion for stability, especially with high-horsepower cars. The back portion is lighter and is available with spring rates from 200 to 255 lbs.-in. to match the weight of your car. The Split-Mono springs are also available in various ride heights to fine-tune the suspension.

Calvert Racing Split-Mono Leaf Springs come with heavy-duty alignment clamps, aluminum front spring eye bushings, and urethane rear spring eye bushings. They are recommended for race use only as the springs stiffen the rear suspension considerably, which can adversely affect ride quality.

Complete your CalTracs suspension setup with Calvert Racing shocks. The CR Series rear shocks have an external dial to set rebound to one of nine settings, which helps you control excessive rear body separation at launch. The CF Series 90/10 front shocks are designed for maximum weight transfer. They have very fast separation and feature dual-stage valving on the compression side to help the car settle on the top end of the track.

Summit Racing also carries Calvert Racing spring sliders, shackle bushings for Mopar Super Stock, GM mono leaf, and Calvert Split-Mono leaf springs, pinion angle correction shims, and spring spacer kits.
