Product details:

The Front & Rear Spring Assist (Load Carrier) by Gabriel combine shock and spring technology to reduce the loss of ride height in ongoing loaded conditions. The constant-rate front coil springs can help improve stability and restore or maintain ride height, while the variable-rate rear coil springs provide 500 lbs. per pair of load capacity [Not to exceed vehicle GVWR (Gross Vehicle Weight Rating). Product does not increase payload]. And like all Gabriel shocks and struts, Front & Rear Spring Assist feature a super-finished chromed piston rod for superior corrosion resistance and a leak-proof piston seal which extends product life.
