MOOG 81069 Coil Spring Set for Chevrolet Tahoe

Ordered the springs Sunday, received them on Wednesday. Installed them today, Friday. It mad a drastic change to the ride quality. Last year I replaced all four shocks with AC Delco brand, but the ride was still squishy. These new springs lifted and stiffened the rear of my 2002 GMC Yukon Xl. Great price, great fit. I changed them in my driveway by myself. Jack up the rear and put jack stands on the frame. Take off both back wheels. Take the bottom shock bolts out and the upper sway bar bolts out on both sides. Take the brake line bracket off of the center off the rearend so you dont damage the brake line. I used a bottle jack on top of the axle and pushed the rearend down one side at a time to change the springs out. Then repeat on the other side. Once the springs are in, use the bottle jack to lift up each side one at a time to connect the shock and sway bar link. Then same on the other side. Once bother sides were together, then I tightened everything up. The new springs are taller than the old ones. Use the top and bottom rubber isolators from the old springs on the new. If your suv feels bouncy or spongy this is the fix. It rides like a new vehicle.

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.

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

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 as Stock= 8 coils, Moog= 9 coils Stock 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 work great definitely nice stiff springs for towing on my 05 yukon

Great deal, old springs were sagging bad and these gave me probably 2 plus inches

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.

I put these on the rear of my trailblazer to get about 1.5 inches of lift and a stiffer rear end for towing. I couldn’t be happier. This is much cheaper than buying rear spacers and stiffer stock springs, and it’s just as easy to install. Having the one solid piece is also more reassuring than having some Chinese plastic spacers back there. I really couldn’t be happier. Just FYI, these are replacements for Tahoe Z71 rear springs. They will make your ride much stiffer, but in the boat that is the Trailblazer that isn’t a bad thing. Being stiffer also means less butt sag when hauling weight or a trailer. It also seems to corner better.
