installation

[buicfrank]

I was going to install Timbren on my 06 Yukon Denali XL. From what I understand 1500s have leaf springs. My vehicle has coils and air suspension. Were coils installed on 1500s? I already have small snubbers there already. I'm just trying to keep the rear up when I tow. Frank

Yukons and Tahoes (suvs) have coils. Silverados and Sierras (pickups) have leaf springs. Your denali xl, like my wife's 2005 Yukon Denali XL, should have the auto air ride which levels the rear. I've never hooked hers up to more than 2500lbs but the stock system kept that load level.

Should I just forget about the Timbren parts? Thanks Frank
