FAQs

Many Calvert Racing parts are shipped with illustrated Install Guides. Please read these guides before starting your project. 

A press will be required to press in the aluminum bushings. DO NOT USE A HAMMER or any other tool that might cause damage to the bushing.

A pair of 1-1/8″ wrenches is required to adjust the pivot assemblies. Calvert Racing offers a set of CalTracs wrenches with a shorter, rubberized and angled handle/grip  designed to make this job easier.

CalTracs do not require welding for most applications.

Standard trucks have the axle BELOW the leafsprings. FLIPPED TRUCKS will have the axle ABOVE the springs. See Graphic below for photos. If you have any questions, please call us at 661-728-9600 Monday-Friday, 8am-4:30pm PST before you order.

Low Profile pivot plates offer 1.5″ more clearance while street driving or strip racing. See below for graphic.

Standard racing two hole (and three and four hole plates for some lifted and Monster applications) allow for adjustments to be made depending on your application’s requirements for desired results during the stresses of hooking  while racing.

For your baseline adjustment, use the hole that keeps your transfer links most parallel to the ground when the application’s weight is full on the tires. Experiment and make any adjustments as success varies from one application to another.

This information, with illustrations, can be found in the CalTracs Installation Guides that come with every set of Calvert Racing CalTracs sold.

We suggest a pinion angle to be between 2-4 degrees negative, measuring off the transmission yoke and pinion yoke.

The HEX end of the bar is for the RH rod ends (silver colored nut) and goes toward the FRONT of the vehicle within the pivot assembly. The SMOOTH end of the bars are for the LH rod ends (gold colored nut inscribed LH) and goes toward the back of the vehicle on the rear mount. Do not attempt to force the threads or you could strip or seize the rod end and/or force transfer bar.

This information can be found in the CalTracs Installation Guides that come with every set of Calvert Racing CalTracs sold.

Standard U-Bolt (1/2″ diameter) torque should be in the 65-70 foot pound range for standard CalTracs.  Truck U-Bolt (9/16″ diameter) torque should be set at about 100 foot pounds. 

NOTE: Re-torquing may be required after break in period. This is normal.

This information, with illustrations, can be found in the CalTracs Installation Guides that come with every set of Calvert Racing CalTracs sold.

Some MOPAR and S-10/S-15 products used two different sizes from the factory. We send both sizes to make sure you get one that fits. The extra set is NOT FOR THE REAR SPRING EYE.

This information, with illustrations, can be found in the CalTracs Installation Guides that come with every set of Calvert Racing CalTracs sold.

CalTracs were designed to use most existing factory u-bolts. To keep the cost to you as low as possible, we only include u-bolts in kits for applications that require them for correct installation. If you would like to purchase new u-bolts, the are available in Parts & Accessories and CalTracs Replacement Parts pages.

CalTracs were designed for high performance drag racing. Running your vehicle on the street may produce a rattle. If this bothers you, before preload adjustments, install a piece of 3/4 inch heater hose fit to the length of the roll pin. This will cushion it against the bar to help reduce rattle.

CalTracs for Trucks have a rubber bushing installed to reduce this effect without interfering with the effectivity of our Traction Bars. If you run your truck without weight in the back, you may still notice a slight rattle on acceleration. This is normal.

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

Replacement parts for CalTracs, including pivot plates, rod ends, force transfer links, rear mounts, u-bolts, and Big Link kits are available separately on the CalTracs Replacement Parts Page.
