By Jeremy P in MO on 4.23.2016
If you want pure beef to use to install that new 8.8, then look no further. Comes with everything you need, and nothing you don't. Customer service is second to none. Only way shipping could've been faster, was if i had picked it up. Came withing 2 days. Great products, great company

Some of the best quality & service with ruffstuff. Can't beat the price or quality on this kit.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Heavy duty product
By Thomas Condon in MN on 1.26.2016
This kit is beefy. I bought this to put an axle from a 98 explorer under my B4000, and it is great. The only thing it doesn't include is mounts for the sway bar. The shipping was incredibly fast. I would definitely recommend this to anyone swapping an explorer axle under a RBV.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Perfect girth and fitment
By Brett Pollard in VA on 1.24.2016
These parts are nice thick material. 3/8" spring perches and u bolt plates. 1/4" shock mounts. Everything fit great and I was very happy with the final product. My only suggestion for Ruffstuff would be that the shock mounts could come longer and the customer could cut them down to size. If you are staying spring under axle but don't want to go to shorter shocks (because they will limit travel), you will have a hard time getting your eye-to-eye measurement the same as with your Dana 35 without relocating the upper mount. I ended up making my own lower shock mount on the u bolt plate. I don't see this as a flaw, but rather a hiccup to be expected with an axle swap. Still a great product that serves its purpose well.

By Rob Block in MT on 11.26.2015
So BEEFY. Such a good price. Perches fit perfect. U bolts are Massive with lots of length for your application. Couldn't ask for anything more. RUFF STUFF kills it again, just like all the previous reviews say. Thanks

By Dylan Dickey in CO on 8.30.2015
Super fast shipping, kit looks super beefy and high quality production. Cant beat this kit for price

5 out of 55 out of 55 out of 55 out of 55 out of 5 Awesome!
By Dallin Peterson in UT on 7.10.2015
Bought this kit a year and a half ago for the 8.8 swap on my ranger. I could't have made a better kit myself! It made the swap so much easier and faster. Even after a year and a half of abuse its still holding up fine! Highly recommend for any 8.8 swap.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Excellent quality, made the job easier
By Lewis Funk in CO on 5.4.2015
I loved this kit. The perches are beautifully made and fit perfectly, and the U-bolts are great quality - the heavy-duty nuts are great. In the past I've fabbed my own perches with 2" square tubing and bought the u-bolts from the auto parts store, but this was faster, easier, looks better, is more accurate, and much stronger - well worth the money.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Seriously Legit.
By Johnathan Abrams in CO on 4.1.2015
RuffStuff has nailed this swap, and it installed like a breeze. The way the spring perches are machined allows you to get a tiht fit on the axle housing to get it positioned perfectly prior to welding. WAY MORE heavy duty than the old 8.25 junk. If coming from stock, U will need a NAPA ujoint part # 353 to fit jeep driveshaft to 8.8.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Wow! More than exceeds expectations!
By Sheldon Belden in ID on 3.28.2015
I purchased this kit for my axle swap on my Ranger, not only was the shipping faster than expected, the quality of the product was outstanding! I actually called customer service to make sure it was the right kit for me, it's made of durable steel and will always be reliable! Thanks ruffstuff my ranger is happy!

5 out of 55 out of 55 out of 55 out of 55 out of 5 heavy duty stuff
By Joseph Clews in PA on 2.28.2015
Well built and thought out. This is heavy duty material and other areas of my Jeep are now weak points. I feel confident that this product will give many miles of worry free use. Thanks.

By Charley Brown in TN on 9.12.2014
This kit is absolutely "Heavy-Duty" and the quality has to be second to none! Dan at RuffStuff shipped the parts out quick and we had a great line of communication throughout my order process. I will not hesitate to order from him in the future.

Question:

Jarrod S. on 11-15-2017 Asked: Does this kit install spring under or over axle?

Answered: This kit is designed for spring over axle applications. These spring perches are 8" long and would interfere with the arc of the spring if mounted under the axle. We do have a "deaver" spring under axle kit that comes with shorter perches.
