MONROE LOAD ADJUSTING SHOCK ABSORBERS
Ideal for light trucks that that tow or carry varying loads, Monroe load adjusting shock absorbers include a heavy gauge calibrated spring that adjusts to road and weight conditions to provide extra control when operating conditions get more demanding.
Hardworking vehicles that tow trailers or carry varying loads can count on Monroe load adjusting shocks to reduce sag when under load. Not just for ride comfort, shocks are necessary for the safe handling of your vehicle. By maintaining vertical loads placed up on the tires, shocks help ensure consistent tire-to-road contact. Shocks also help maintain a balanced ride by providing resistance to vehicle bounce, roll and sway as well as brake dive and acceleration squat.
CAUSES & CONSEQUENCES OF SHOCK FAILURE
Like many parts on your vehicle, shocks are subject to wear. Causes include damaged bushings, exposure to the elements, loss of oil viscosity and deteriorated components. Driving with worn shocks can result in problems ranging from reduced braking efficiency, tire wear, loss of stability and damage to other suspension parts.
IMPORTANCE OF MAINTAINING RIDE HEIGHT
Proper ride height is crucial to vehicle durability, performance and safety. When inspecting a vehicle, don’t just check the static ride height. The dynamic ride height –the ride height of a vehicle in motion –may tell a different story. The cause of dynamic ride height issues is often worn or damaged coil or air springs, depending on the vehicle suspension. Don’t just replace the shock –be sure to also inspect for and replace worn coil/air springs.
IMPORTANCE OF ALIGNMENT
Always perform an alignment whenever replacement shocks, struts or other ride control parts are installed. Camber, toe and caster settings can all be affected by installing new shocks. Failure to make sure the vehicle’s alignment is within factory specifications can lead to problems like premature tire wear.
HOW TO CONDUCT A SHOCK INSPECTION
Shocks may not show any visible signs of wear, make sure to request a ride control inspection every time your vehicle is brought in for service to ensure they’re in optimal operating condition. When inspecting a vehicle’s shocks: assess how the vehicle is used and perform ride and physical evaluations. Get an understanding of the vehicle’s repair history, the way the vehicle handles and its intended use for clues if the shocks might need changing. Next, take the vehicle for a test drive to determine whether the vehicle’s steering, stopping and stability are compromised. Wrap up the inspection with a physical examination for symptoms of wear which may indicate new shocks are required.
Installation Notes
-
Replace both rear shocks (this kit includes 2)
-
Inspect control arms and bushings
-
Verify compatibility with electronic suspension
-
Torque to factory specifications
Because mismatched rear suspension makes things weird fast.
Final Verdict
The Monroe Load Adjusting 58639 Shock & Coil Spring Assembly (Pack of 2) is a smart upgrade for Chevrolet Tahoe owners who tow, haul, or regularly load their SUV. Added support, improved stability, and restored ride height—all in one assembly.
Because sagging rear ends belong in memes, not SUVs.

So far this has been a really great purchase! I came here after Detroit Axles shocks fell apart after only a week and me sounding like crunchy knee caps even going over the smallest bump. Wish Monroe had the front coils like this but I’ll be getting those elsewhere. I could feel the difference right after install they adjust to weight automatically and dont mess with the oem ride height. Just install and go. They are sturdy like the oem A/C Delcos heavy duty towing shocks. Im kinda sad I paid $127 for them to drop 40 bucks the next day but whatevs. Buy them!2004 GMC Yukon SLT 5.3 V8 4×4

This is my second set purchased, both for older model Yukons- amazing results, highly recommended. On the second Yukon, switched air suspension to these and the ride/stability is superb.

Amazing difference! Replaced for 2004 GMC Yukon XL with ZW7 smooth ride suspension and non electric non Z55 autoleveling Novamat shocks. Added about an 1 inches in the rear but it looks better that way. Much cheaper that the Novamat shocks and rides firm and smooth.

First off I purchased these for my 2005 GMC Yukon Denali XL. It had the air ride suspension but I was really sick of repairing that so I tried to figure an alternative. I used coil springs and bilstine shocks at first which was a nice ride but if I put any significant weight in the back it caused sag. After asking around a little bit someone told me about these coilover/strut like shocks. These work amazing! They bolted right in and are much stronger and more supportive then the shocks alone were. If you are thinking about adding these to your Yukon I highly recommend it! I don’t think it said they would fit, but they definitely do.

Easy swap. Will raise your end up almost 2 inches.

Great shocks…. they make a huge difference in the handling. EZ to DYI.

It helped with the extra weight that I was hauling pulling a 7000 pound travel trailer with my 2003 Chevy Tahoe. Plus I was also using airbags that went inside my coil Springs All in all it stabled out the ride for a long haul

Great value for the price. Works well on my Chevy Tahoe towing a 6000 pound trailer. Made the ride smooth with or without tower.
