Hello, everybody. This is Jeff at etrailer.com. Today, I'm gonna take a look at this Spacer Kit for the Timbren Suspension Enhancement System. Now this spacer kit is designed to adapt your Timbren Suspension Enhancement System to your lifted vehicle. Now, this kit will include everything laid out here on the table. It'll include two of the one inch thick rubber spacers, two of the 1/2 thick rubber spacers, does include the bolts, and there's three different size bolts.
You got two of the 2 3/8 inch long bolts, two of the 2 9/16 long bolts, and two of the 3 1/8 size long bolts. It does come with a nice set of instructions that'll describe how these install. But basically, to determine if you need this spacer kit for your application, What you'll do is measure between the frame of your trunk when it's empty and the rear leaf spring. And this spacer kit is required for measurements that'll measure between six inches and 7 1/2 inches. This will help fill the space between your suspension system and the lifted frame.
Now, you can mix and match the spacer sizes to fit your vehicle, but you wanna make sure to use the correct length bolt for the correct spacers or spacers that are gonna be used. So basically, if you're just gonna use the 1/2 inch thick spacers, what you'll want to do is use the smaller 2 3/8 inch long bolts. If you're gonna use the two one inch size spacers, you'll use the 2 9/16 long bolts. And then if you're gonna use a one inch and a 1/2 inch one combined, then you'll use the longer bolts which are the 3 1/8 inch long bolts. But that should do it for the review on this Spacer Kit for the Timbren Suspension Enhancement System..
A Yah , be careful with this one, the bimbos at etrailer said oh, yah . Reality check , be careful this is a adder to basic kit, Do not use if it prevents a min. of 1" of free space from rubber to frame. I got some BAD advice from e trailer on this, contacted manufacture, they said must have free movement from bumper to frame, will close on loading
After receiving my initial order of bump stops that I was told were the correct ones for my truck I learned only after installing them that they were not correct. I was subsequently told that on a rare occasion some of my model truck have a larger space then expected and to solve it I’d need to buy the extra spacers I just got those today and was expecting two sets of 1” thick spacers. Instead I received one 1” and one 1/2”
The instructions state after installing these that I should have a gap m o bigger than 1 1/2”
I will have at least 2” of gap because the spacers are not big
Enough
Have 2022 GMC 2500 HD AT4. Because it sits higher I had to buy the spacer kit for the Timbrens that I purchased from e-trailer. I added an extra half inch spacer and that was perfect for towing fifth wheel
Hardware didn’t match the previously installed Timbren GMRG25C kit. I had to purchase my own hardware which wasn’t a problem but makes the kit purchase irrelevant.
After my initial purchase, I determined the kit needed an additional spacer for my 2023 F350 Dually. I contacted customer service and they immediately shipped me the spacers I needed. Thank you etrailer.
They are heaven. Im so happy with them. They do exactly what they say they do. I love them. Ive been recommending then to every person with a truck or van. Thank you. They are amazing. Wish I would have know of timbrens years ago.

Works great fit just right and just as good as much more expensive air bag systems.
Works as expected and shipping was quick
Spacer kit made for easy set up. I set mine with a 1” gap to the axle pad. Helpful when pulling my boat with the 1/2 ton.
I ordered the bump stop spacer package cause I forgot to order it originally and I tore the bump stop bracket off when I was out offloading and so I ordered the space kit and for some reason it skip my options for shipping so I reached out to Jason and he upgraded to second day shipping they arrive Thursday because tomorrow they’re going to weld back on the bump stop bracket and put the bump stops on
Every thing was great from customer service to product received
Fit perfect
Definitely helps compared to the oem
Great kit came exactly as ordered easy to install and made the Truck handle so much better when towing!
Very good quality and easy to install. Needed the extra 1 1/2 shims because my tundra has a factory 3" lift.
Nice kit. Good components solid hardwar e.
Daylon and the team were an incredible help! Got me the product very fast!
The spacer product is fine, I just didn't need it. The return process was sent to me, but it's too costly to send back. I would give the product a 5 star if not for the return issue.
Bought this because I had a leveled and adda block to the rear if my truck. It should work well to keep the proper distance and keep from looking nose up.
Bought these for my 13 toyota tundra with spacer kit because of the lift, used them for hauling my camper, did not need weight distribution bar anymore pulled good, also use this for my 7x14 dump trailer hauling gravel made a big difference, dump trailer weighs 4400lbs and would haul 3yards of rock regularly
The bolts that come with it is not long enough to use both of them together
Worked for what intended

I had been having problems with both the factory bump stops and replacement stops lasting for any longer than a year or two. They would completely come off from just daily on/road use. Replaced them with the Timbren stops and my ride has been the best it’s ever been since I have had the truck. On road or off didn’t matter. Has done particularly well this winter off/road while working on a construction site. No bottoming out or heavy swaying while hitting those ruts and bumps onsite. The truck was lifted 6” and I had to get spacers which I forgot but etrailer sent them very quickly and I installed them with very little effort. Was surprised how little time it actually took me. Didn’t have a lift so had to use jacks which took up the most time on the install. I’ve had them on for a year now and would say it’s one of the best products I've ever put on my truck. Wish I had done it years ago.
Super fast service. Super easy install!
Work great
I paid extra shipping to receive it before I needed to haul my boat to Lake Powell. It didn’t show up until the day the free shipping date was. So I had to have my friend tow it for me.

I have used the Timbren helper springs on 3 of my trucks now, including last year when I bought them for my 2023 F350 Super Duty 4wd from etrailer. Before that I had 2 Super Duties with air bags. After buying my first Timbrens, I was hooked! They are simple, affordable and work great. I just bought my 3rd set for my 2024 Tacoma Off Road. I also am a fan of etrailer!
