SPRING PERCHES FOR 2.75″ AXLE TUBE
Set of (2) Two Perches. Fully enclosed for added strength, pedestal tabs ensure heat penetration when welded to housing. Perch extends to center line of axle tube for more surface area. Precision laser cut. Requires welding to axle, see graphic for info.
Check out the comparison graphic to see how Calvert’s patented Heavy Duty Perches compare to other manufacturer’s stock perches.
Patented HD Axle Perches. Universal design fits nearly every application. Available to fit the most common axle tube diameters; 2.25″, 2.5″, 2.75″, 3″, 3.25″ and 3.5″
WELDING ONTO AXLE: Pinion angle recommendation is -2 to -4 degrees when used with CalTracs. NOTE: This is the angle of the pinion in relation to the angle of the output shaft of the transmission, NOT the driveshaft. Add the angle of the pinion yoke to the angle of the output shaft with the vehicle sitting at rest with weight on the tires.
SET OF TWO SPRING SLIDERS
Designed to fit Calvert Leafsprings installed on ALL CARS & TRUCKS (except Chevy Bel Air). Outside diameter aluminum bushings: 1″.
May also fit most Chrysler factory springs due to rear bearing size.
Heavy Duty roller bearings keep the leafspring and body from binding up during suspension movement. Replaces the existing shackles.
