LEFT MX Rear Mount and hardware to upgrade your current CalTracs to CalTracs MX without sacrificing ground clearance
Chevrolet S10 with shock mounts.
***To get the most out of your CalTracs, we recommend that your installed CalTracs bars are close to parallel to the ground when fully loaded. Sometimes that configuration is difficult to achieve depending on the mods or equipment you have installed on your drag race car. CalTracs MX helps solve that!
Made with 5/16″ mild steel to withstand the correct torque on your u-bolts and keep your rear-end from moving. UPGRADED HARDWARE included. Black gloss powder coated for extra durability.
RIGHT MX Mount available, part # MTX-37R

Designed with dual compression valving, Calvert’s CF Series 90/10 Drag Shocks were engineered for cars with mid-range power for softest rate of rebound on the market to allow for better weight transfer and more weight over your rear tires.
Built-in high-speed valving keeps your front end from bottoming out on hard landings. Once you’re out of the hole, low speed compression is active, and a softer valving allows the front end to settle at the top end. Every application has been evaluated for best length, assuring that each vehicle has sufficient travel for maximum traction unlike other manufacturers who model their shocks after factory length shocks. No adjustments are required; designed to perform right out of the box. Lightweight, industrial design.
