Frequently Asked Questions
Do I really need a rear frame stiffener on my Defender HD11? If you are running oversized tires or heavy upgrades like portals gear lifts or long travel suspension, we recommend you also install a frame stiffener. A frame stiffener will help protect your frame from the added stress of these heavy accessories.
