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.
FRAME RAIL TIE DOWN BRACKETS help control up and down/vertical movement of your vehicle in your hauler/trailer to reduce wear on your suspension system, including springs and shocks.
3/8″ Raw Steel (to facilitate welding), 90 degree angle to fit frame rail. Must be welded to rail, see photos for recommended weld placements. NOTE: When securing your vehicle to the trailer, compress the vehicle ONE INCH MINIMUM for best results.
Combined with our regular Tie Down Brackets, your vehicle is secured against side to side AND up and down movement within your trailer/hauler to protect your vehicle!
