MOOG 81069 Coil Spring Set for Chevrolet Tahoe

This spring is the equivalent of the one used on the Tahoe/Suburban/Yukon "Z71" packages. This gives you about and extra 1” lift from a measurement standpoint on a suburban. To my knowledge this is the only Heavy Duty spring you can get without getting into increased suspension lift. Air bags are another option if you want to deal with it. The LS, LT and other models use a softer spring that is a bit wider in the coil configuration and less coils overall. This 81609 has a tighter coil package and the steel coil is thicker, I want to say the standard coil is 5/8 and this one is 3/4 . A tahoe/trailblazer website discussion forum has details/pics on it if you wish to search the web for further details.Install is pretty simple on a suburban, disconnect lower shock bolt and sway bar bolt holding axle. Jack frame of vehicle up high enough to pull old spring out and insert the new spring. Reverse order of putting everything back together… Keep an eye on the rubber brake lines while you jack up the vehicle that you don’t put too much tension on them that they rip apart. They will get tight so be careful on how high you raise the vehicle during this process. If you don’t know what I’m talking about go somewhere and have it done for you. I'm not liable for the instructions I'm providing.Comfort of ride did not change in my vehicle,, maybe not as of a spongy ride,, but really hard to feel any difference. Definitely did not provide a harsh ride afterwards. My use was for mainly for towing so I wanted the ride height of the vehicle to hold the trailer tongue weight better than the stock softer coils.

Perfect fit, easy install and my truck has a great stance now. I removed my factory 17 year old worn out springs and garbage air shocks (which I replaced 3 years ago and they’re shot again). Jacked the back of the truck up a little; removed both shocks and disconnected the sway bar links. Jacked the truck up higher. Pulled the springs out by hand. Placed the new springs in, lowered the truck down a little. Installed a set of Billstein 5100 shocks and bolted the sway bar links back up. Tucked away the air and electrical connections for the old air shocks. Lowered the Jack all the way down. Deleted the autoride by disconnecting the battery negative, pulling the RTD fuse and reconnecting the battery.I got a full two inches by doing this and now my 285/75/r16 (33”) tires look perfect. Stance is great. The ride is AMAZING. No more mushy bouncy ride. It’s not harsh at all, just firm. Handles great, on the road and in the woods. The ridiculous compressor doesn’t randomly kick on and I don’t get any lights on the dash- because I properly deleted autoride. No problema. Highly recommended. If you have a vehicle equipped with autoride and are afraid of it, don’t be.

These coil springs are very nice. Got 2.25 inch lift increase on the rear of my Tahoe. Ride is a lil bit stiffer but still pleasant. Super happy with these springs. Highly recommended

The springs on my 09 Tahoe were shot. Wheel opening on drivers side 5.5 inches from tire to fender, 4 inches on pass side. Installed these now 7 inch clearance both sides. Install time about 2 hours. Plenty of videos on youtube. Make sure to use new lower spring pads because they are usually beat up and you don't want metal to metal. Ride is a little more stable with less rear sway. Install by jacking up both sides of car until rear tires are off ground, springs are extended and loose in the pocket. Place jack stands on frame rails. The items needed to be removed are wheels, lower shock bolts (use jack under rear differential to remove pressure from shocks and sway bar links) sway bar links upper bolts, wheel speed cable from frame rail so as not to break it, and bolt from brake line bracket on top of rear end.

Recently put 4” lift spindles and 3” spacers in the rear of my Tahoe. It sat about .5” lower in the rear. These springs were recommended on many Tahoe forums, installed them and it added 2” to the rear. Gave me the factory 1.5” rake in the rear. Springs ride good and very satisfied!

Even though these springs are supposed to be a heavier spring rate than stock, they are pretty soft.

Well it was time to replace the tired stock coils on my Z71. After 12 years and 152,000 miles, they seemed a little softer than before, and possibly started to sag a bit. I was worried that these would not carry the load or be as tall as the Z71 springs(taller and more load) than standard coils. After days of searching the web, I was confident enough to get them, and boy am I glad I did!First: These ARE the Z71 equivalent coils....I have a Z71! My old coils measured at 16 3/4" tall, these are 17 1/2" tall, which is probably what the OEM Z71 coils use to be many many many miles ago. So if you are looking for a Coil to replace/upgrade to give lift......these are the ticket!In comparison, there are a few differences between the two, such asStock= 8 coils, Moog= 9 coilsStock are thicker.......BARELY!!! (I could see a difference, but i don't have a gauge to tell you .....it was MAYBE 1/16-1/8)Stock are Wider in diameter measured at the middle coils. Top and Bottom plate coils are the same.Stock= 16.75" tall, Moog= 17.5" tall (could be due to age/mileage)Stock was softer.....as in easier to push down on.(could be due to age/mileage)Overall super happy with these. Truck stands much taller now (39.5" at fender with stock tires). I did change my shocks at the same time as well, so the ride was much better. I notice less bounce than before and there is much less give under load on the bumper.

These seem to be doing great one month later and I pull 2000 to 4000 pounds every other day on my tahoe. It has done great on the horrible pot holes every where in Alabama!
