Product Details

The TeraFlex Front Axle Inner Knuckle Gusset Kit is an essential reinforcement upgrade for 2007-2018 Jeep Wrangler JK and JK Unlimited models equipped with Dana 30 or Dana 44 front axles. This lower knuckle gusset kit addresses a critical weak point in the factory axle design by adding substantial reinforcement to the inner knuckle area.

Key Features:

  • Reinforces weak inner knuckle joints on factory Dana 30 and Dana 44 front axles
  • Prevents unwanted bending and breakage under extreme off-road conditions
  • Lower gusset design provides targeted reinforcement where stress concentrates
  • Sold as a pair for complete front axle protection
  • Designed specifically for JK Wrangler 2-door and 4-door Unlimited models
  • Ideal for lifted vehicles, larger tires, and aggressive off-road use

This gusset kit is a must-have upgrade for serious off-roaders who demand maximum durability from their front axle assembly. The precision-engineered gussets install directly onto the axle housing, significantly increasing strength and rigidity in the critical knuckle area where factory axles are most vulnerable to damage.

First off, I LOVE my new shipments! These guys had everything at super low prices, and the shipping was phenomenally fast. It's all working great, and imm definitely buying from these guys again.

Like the simplicity so far. Ordered my product on Sunday shipped out Tuesday so we'll see how fast and efficient shipping is.

Shopping was easy and quick

Autoplicity had the lowest price I found on the product I wanted. Also, the item was shipped very quickly. I received 2 days after I purchased it. Great service!

Great Place to shop for Auto Parts Very Fast shipping

I am extremely happy with Autoplicity from start to finish! They had the best prices online on Hawk Performance pads and were shipped the day I ordered. They were at my door step within two days of me ordering them! You can't beat that anywhere. Cheaper and faster, it truely dosen't get any better than that.

Comparable pricing, fast trackable shipping.

Great prices, and much faster delivery than expected. They "over-delivered" on what they said they'd do. Will definitely use them again!

Great prices. Easy order placement through Amazon. Let's see how fulfillment goes.
