Couldn't figure out how to add Pass Side Stiffener work to previous review so posted this additional review. The pic associated with this one shows Pass Side Stiffener welded with weld locations seam sealed prior to using Eastwoods xtreme Platinum product (4 hr flash time) But needed to wait 48 hours to fully cure before next step. After 48 hr cure, used Eastwoods xtreme Chassis Black, 2 coats (15min flash time). And Finally will rubberize.
Any Salt Belt driven xj will benefit from rust mitigation. This frame stiffener is just what my auto body technician needed. The most common issue seen in the review pictures (seen here and elsewhere like naxja and jeepforum) is a rusted out Fuel Hose Frame Pass-Thru (if that's what they call it). Luckily, only the oval shield insert on the Fuel Hose Frame Pass-Thru needed to be re-fabricated. Frame steel good but stiffener's definitely needed. Opted against using Dirtbound's custom Leaf Spring plate that relocates axle snubber but had to deal with a broken snubber bolt (re-drilled and tapped) so had to enlarge stiffener relief hole for that snubber bolt. (will post pass side soon)
Good quality steel, great customer service, couldn’t be happier.
Awesome Purchase.. My son's 2001 Jeep frame started to show some age with rust here and there. These Stiffeners fit like a glove, did some rust cleanup with a grinder and placed the stiffeners, welded them up and primed and brushed on DIY bed liner and it looks great! Not to mention firmed everything up! Thanks for a great product!!
excellent quality! manufacturing and shipping took longer than expected however was worth the wait
I purchased these to put on following some major unibody rehab on my 01 XJ. These fit the frame shape well and look nice and heavy duty. i did have to widen the very rear 7 vertical plug weld slots by drilling a couple holes in a row up the slot. Not a huge deal but I feel 3/8 wide would be perfect.
Love the product was In awesome shipping box packaging really good. It was a bummer there was no instructions and for spending a few hundred dollars not to get any awesome stickers or a hat or t shirt was a little disappointing
Awesome product. Chose your company after watching several installs on YouTube.
Fit and worked good my jeep didn’t have a rear frame left or a shackle mount, these added enough strength to buid my new frame and connect it up to a solid frame
Great product!!! Highly recommend to anyone with a jeep xj!!!
