Axle BELOW Leafsprings

Designed by Drag Race legend John Calvert. Bolt On traction system. Full pre-load adjustability, keeps axle from rotating/maintains pinion angle, improves 60′ times. Black powder coated for durability. Low Pro, 2, 3, and 4 hole pivot plates available (hole count refers to link/bar adjustment holes, not the top two install holes).

MADE IN USA

NOTE: U-bolts NOT included in the kit unless specified. Some applications require additional hardware.

CalTracs were designed for high performance drag racing . Running your truck on the street may produce a rattle, especially if you are not running any weight in the back. 

DEFINITIONS:

(w/flip): Trucks that have had a flip kit installed and the axle is now ABOVE the Leafspring. Please call if you have any questions.

(staggered): Trucks with Staggered Shock placement, ie: driver’s side inboard behind the axle and inboard in front of axle on the passenger side. Please call if you have questions.

***

Detailed full color illustrated Installation Guide included with every kit.   PLEASE READ COMPLETELY BEFORE INSTALLING CAL TRACS.

CAUTION: Do not over-tighten the bolts or rod ends; these need to move freely for CalTracs to work without binding.

Starting at $419

Kits w/required U-Bolts: $469
