This Belltech 4230 Coil Spring Set is awesome to make my 2004 chevy avalanche lower around 4" drop. Worth my money for real. When I've been looking for lower for my avalanche but they want lift or stock on my avalanche which is piss me off. But this is only one if you are look for to lower your avalanche. If you want lower on 2000 to 2006 Chevy SUV, Tahoe, and Avalanche you can go with this with Belltech 9513 Shock Set to achieve lower than the stock.

Put these in the rear of my 04 Tahoe. Dropped more than the mcgaughys 3 inch ones I had. Only thing is they bottom out easily as they are for a trailblazer but I installed some helper bags with them 60748 is the part number that fits in these. Rides great an is low. Thinking of cutting a coil an going lower.

Lowered My 2007 TBSS in the rear and deleted the air bags. It sits level with the front and gives a mean looking stance.

I replaced the air-bags with these springs in my '06 and '07 traiblazer SS's. Very little effort or mechanical knowledge required. Jack up truck, support axle, disconnect shocks, drop the axle, twist the bags out, drop the springs in, jack up axle, connect shocks, set truck on the ground. These springs feel a bit more firm than the bags but def not harsh or hard. They take away the sloppy cornering that the bags provided. Also snapping back from a big fishtail feels a little less violent...lol. There is still no wheel hop when spinning which is good and they dropped the rear end about 1/2" for me (fenders sitting at 32").

Bought these as part of the replacement for the airbags in the rear of my Saab 9-7x (Envoy, Rainer). Good product but make sure you are buying the shortened shocks to go with. The rear sits now at 31" which is a little low so spacers will be needed if you want more of a level look.

They work for sure. Be sure to get 20.5" extended length shocks, otherwise the coils can fall out on a frame lift or any other means of over extending the suspension. The grey finish is nice. Be sue to wrap sliced heater hose or something on the body mount end of the coils.I wish they were progressive rate springs as well. Be sure to use the shorter shocks like I mentioned earlier.
