They're installed blue thing up in the Tahoe, but I pulled mine off for more clearance to the fuel tank. The blue thing is a clank-reducer because the Tahoe springs are progressive-rate. Our OEM springs are constant-rate. The Z71 springs are designed so some of the coils will collapse to solidity (and touch) before the others, then the effective spring rate goes up due to the smaller number of coils being deflected.
