Review on 🚗 Enhance Your Vehicle's Suspension with Firestone W237604138 Coil-Rite Kit by Joseph Harkins

It also takes about 2 hours to install. The 2016 Sedona had a 5/8" groove under the spring seat, which allowed me to drill a 1/2" hole with just the rear wheels off the ground. With springs uncompressed, there was enough room to remove the bump stop, install the bracket, and compress the bag through the coils. The hardest part was drilling the hole in the middle. The burrs from the hole were difficult to remove, but everything worked out. At 15psi, the unloaded tail is about 1/4 inch higher.
