Product Features:
- REDUCES SAG UNDER LOAD - Ideal for occasionally hauling or towing varying loads; heavy gauge, calibrated coil spring reduces sag when loaded up to 1,200 lbs. (capacity limited by suspension, tires and transmission; see owner's manual)
- EXCEPTIONAL HANDLING - Tuned specifically for each application, full-displaced valving automatically adjusts to road extremes to provide ride consistency

- IMPROVES PERFORMANCE - Nitrogen gas-charge maintains tire-to-road contact for improved ride and handling by reducing aeration and shock fade
- Nitrogen Gas Charged: For Improved Ride & Handling, Helps Maintain Tire To Road Contact By Reducing Aeration - On Most Applications

Most Liked Positive Review
Surpassed my expectations
The Monroe sensatrac shock absorbers were easier
to install than I had planned on. Being a fulltime rver I made this purchase to add stability while towing our fifth wheel trailer.
I expected the ride to stiffen and maybe even be harsh when not towing. After installing these shockabsorbers (which took about 30 minutes) the
truck was much more stable and amazingly the ride was less harsh than before. I would highly recommend this product to any one who hauls loads
with their truck, tows a trailer, or just wants a
little more stable ride. My shopping experience
online and delivery of the product could not have been easier.

works well at first
installed on my truck 5000 miles ago and for the last 2000 miles they have been very noisy from the spring rubbing on the insulator that is over the shock and now the insulator is gone and the spring is cutting into the shock body making an awful screeching noise. They did work very well at first. I will replace today

Leaks/Rusts
These shocks are surprisingly the worst shocks I ever purchased. The paint finish appears to be a thin top coat without primer, causing to rust very quickly. The piston rod, which appears to be chrome plated is rusting and has caused the shock to fail, by leaking oil. Everything about this shock is a failure, including the price I paid for them. Unfortunately I can't find my receipt to get something to replace them with through the manufacturers warranty. But, on second thought, why would I want to. A total piece of junk. Monroe,your fired!
Bottom Line No, I would not recommend to a friend
2004 F150 Lariat 4x4. 316000 miles. 5.4
These coil over shocks are GREAT!!! Easy to install. This truck had , what I'm assuming were original shocks. The shocks went on with no trouble, other than having to jack up the truck so the extra length would allow aligning the mounting holes with the shock length. Made the truck ride like my wife's 2011 RX350 Lexus.
Bottom Line Yes, I would recommend to a friend

Nice Lift
Verified Buyer -
Just what I wanted, truck no longer squats under trailer load. Rides good unloaded. Easy to install. Finish was poor. Had to paint shocks before install. Unpainted welds would have rusted and failed prematurely.
Bottom Line Yes, I would recommend to a friend
My 2nd set, great price, great delivery.
Verified Buyer -
These increase the height by 1/2" just what I needed to match the 2.5" steel level kit for the front. This is my second set and I can increase the bed load as well as trailer my UTV without much sag! I can also fit 35" tires all the way around on my F-150.
Bottom Line Yes, I would recommend to a friend
