Put them in a 97 F350. Only been in for about a year and 10k. So far so good. Did not notice the ride get and harder, definitely tightened up the steering a bit and took a lot of axle sway out of the front. Going to do my other 97 soon with the same!!

Made my truck ride and handle great, brought the front back up at least an inch. Easy to install once the old parts are out. Check out the parts before you begin, I had the center diameter wrong on one of the steel pieces in this kit and one in my pivot bushings.
5 out of 5 - Great product.

95 f250 powerstroke ttb 4x4. I was having severe tire wear and extremely rough ride and front end wandered badly. I replaced all the front suspension bushings with factory style rubber ones from a local parts store. It corrected my ride height and alignment for only a week before the new bushings started cracking and sagging again. Right away I ordered this poly bushing set. The installation was very simple. It has been over a month and my truck rides and handles better than it ever has. Smooth ride, drives straight down the road and no clunking over speed bumps. Im very satisfied and will use this product again!

Firmer ride.Not the easiest install but worth the effort.

noticing some give and flex in them. The mag-chloride (road clearing chemicals) looks like it is eating away the metal centers. Perhaps stainless steel centers would be better for road salt resistance? Editors note: The anodized to provide rust prevention in normal operating conditions. Road clearing chemicals will degrade any steel product over time.

Hi.it seems to work just fine the year i have been driving on it . but id rather would have them a little bit wider and then harder to get them in the leafs, that way they will last much longer on such a heavy car as my 350 ford xlt ,other than that OK, thanks G.G.

They were easy to install had the press old wore bushings out which is a given. I sold the truck but could definitely tell a difference in the front end :)

Dwain A. Wagoner - . Energy Suspension 4.2121
When i changed the bushings i noticed the leaf bushings have been changed before. But my shackle bushings were still stock.Beyond normal wear and tear. I was quite impressed on the test run because the handling and overall ride quality was 100 X better.

I ordered these along with the axle pivot bushings. I should have done this a long time ago. These were installed on a 1995 F250 4X4. Even with the bad design of the TTB front axle, these bushings make all the difference in the world and in my opinion are an absolute requirement. Without these bushings you will have trouble holding an alignment if you can align it at all. My truck never drove so well.
5 out of 5 - Outstanding
Dale A Schrock - . Energy Suspension 4.2121
I re-did my whole front suspension bushings, these are top of the line and worked perfectly. I am very happy how it turned out!
5 out of 5 - great quality perfect fit!! couldnt have asked for better!!
Craig Reinhart - . Energy Suspension 4.2121
Installing these new bushings was easy. Getting the old stock OEM rubbers out was a PAIN. Just use a torch to heat up the leaf spring "eyelet" until the old rubber is HOT and they pop (push) right out. Cut out the OEM steel liner and use a wire brush to clean the leaf spring eyelet. The new bushings slide right in with the silicone lube. They do not sage like the old rubber bushings. Definitely tightened up the front suspension. Other brands require the new bushing to be pressed in, these are DIY bushings.
5 out of 5 - Great
Adam King - . Energy Suspension 4.2121
My F250 has 76000 miles on it and the factory rubber bushings were worn out. The energy suspension bushings are well made and won't wear out in 76000 miles.
5 out of 5 - Very good proudct
mark gattoni - . Energy Suspension 4.2121
Only complaint might be better instruction on the need to reuse steel shell or not. With average customer, it might not be an issue, but I have sold/installed many different part numbers over the years and some have required reuse of original shells, which really makes the job difficult.
5 out of 5 - pleased

Very good quality. Hardest part was getting the old bushings out. Cured my squeaking problem. Overall very nice. Highly recommend.
5 out of 5 - awsome
joe kramar - . Energy Suspension 4.2121
After ordering energy suspension products once before, its about the only suspension products I'll buy now! High grade products, easy installation, oil resistant materials. Wayyyyy better than oem rubber or rubber at all! I recommend to anyone.
5 out of 5 - Very great product! Easy to install and 10x better than own rubber.
Travis Burris - . Energy Suspension 4.2121
Yes, the parts have been installed and I am very pleased with the product. I will be ordering bushings for the rear suspension soon.

I am very pleased with the product. I had read good reviews on them before. I was very happy with the service as well.
5 out of 5 - very well made
Ritchie Putnam - . Energy Suspension 4.2121
I went all out and installed all new bushings on our 93 F350 4X4 7.3 on the front and rear springs. Made a huge difference in the driving feel. A lot less wander on the road. Tighter feel at the wheel. Don't have to fight the truck to keep it on the road. The metal shims can be a pain to remove from the old springs but be patient. The results are worth the effort.
