think i might replace the shocks on my 07 qc 4x4 1500 ram, has about 49k miles. Jegs has a set of skyjacker shocks in stock for my truck, are these a good brand of shock? What about removing the shock absorber, they have the coil spring right over the shock absorber, do i need a coil spring compressor. When i purchase new shocks, do i need a set with the coil spring built into them like the oem one's
