If you drive a 2005-2015 Toyota Tacoma Double Cab SR5 V6 Off-Road Package you need these front shock absorbers. The truck comes with a Bilstein 4600 which is an instant upgrade. I leveled the truck by setting the shocks to 1.5 inches, it raised the front just enough to make it look good, but it's not "moonshine" (front bumper is higher than rear) . Simply find a tire dealer near you. with a spring compressor and let them switch places; These springs are thick and I wouldn't trust them to a McPherson strut compressor.
