034 Motorsport - Solid Rear Sway Bar Adjustable for Audi B5 A4/S4/RS4 Quattro - 034-402-1001.

034 Motorsport is proud to offer the ultimate rear sway bar upgrade for the B5 Audi A4/S4/RS4 Quattro! The 034Motorsport Adjustable Solid Rear Sway Bar is made from high-quality spring steel for maximum rigidity, and is designed to combat understeer while reducing body roll under hard cornering.

Pair this with: rear subframe reinforcement

* please note all 034 motorsport sway bars are made from solid steel. Do not choose your sway bar on thickness alone.

This product was tested thoroughly on the street and track on our shop B5 Audi S4 before release. The 034Motorsport Adjustable Solid Rear Sway Bar substantially reduces understeer and body roll on B5 Audi A4/S4/RS4 Quattro vehicles without compromising comfort on the street.

In addition, the 034Motorsport B5 Audi A4/S4/RS4 Quattro Rear Sway Bar is engineered to be used effectively with the stock front sway bar. No upgrade in the front is needed or required. The addition of a stiffer front bar introduces even more push, requiring an even bigger bar in the back.  With the stock front sway bar and upgraded 034Motorsport Solid Rear Sway Bar, body roll is virtually eliminated while turn in and off throttle oversteer are greatly improved.

Features:

  • 213% - 330% Increased Sway Bar Rate (Over Stock B5 Audi S4 Rear Sway Bar)
  • 142% - 220% Increased Sway Bar Rate (Over Neuspeed 19mm Rear Sway Bar on the Stiff Setting)
  • 25.4mm Diameter
  • Solid Spring Steel Construction
  • 2-Way Adjustable
  • Designed to be used in conjunction with the stock front sway bar.

What's Included:

  • 034Motorsport B5 Audi A4/S4/RS4 Quattro Adjustable Solid Rear Sway Bar
  • Graphite-Impregnated Urethane Bushings
  • High-Strength Billet Aluminium Sway Bar Brackets

Fitment:

  • B4 Audi S2/RS2
  • 1996 - 2001 Audi A4 Quattro (B5)
  • 2000 - 2002 Audi S4 (B5)
  • 2000 - 2002 Audi RS4 (B5)

Installation Instructions:

Please Note: The use of a rear subframe reinforcement bracket is required with this sway bar. The rear subframe is prone to cracking with an upgraded sway bar, and will likely crack if you attempt to use this sway bar without subframe reinforcements. If you do not already have a subframe reinforcement kit, you must purchase the 034Motorsport Billet Rear Subframe Reinforcement Bracket. This sway bar fits Quattro vehicles only.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.
