so heres the skinny, the top plate is different. the tundra bolts are about 1/8" more separated. the good news is, i was able to use the DR perch on the king shock. the UCA is at an angle more like stock (i managed to find a stock 4runner to compare). i will have to crank up the coils cause the tires are rubbing against the mud flaps at full turn and i want a bit of a cali lean GNAR!! hopefully i can get the UCA angle to come down with the coil cranked a bit. the truck feels great. stiffer than the DR's, feels more like the bilstein 5100's. theyre used so maybe thats why the feel great.
