Can-Am Defender HD11 & Defender MAX HD11 Atlas Pro 1.5" Rear Offset A-Arms, 38 mm Tubing, Adjustable Camber, Preinstalled Bushings, Up to 34" Tires, Lifetime Warranty

Bigger tires need more room, and factory A-arms take a beating on logs and rocks. These Atlas Pro rear offset A-arms move the Defender HD11's rear ball joints back 1.5" for more tire clearance and a longer wheelbase, and their thick-wall tubing is built to take hard hits.

Highlights

• 1.5" rear offset
• Up to 34" tires in the rear when paired with forward offset A-arms, no lift required
• 38 mm tubing
• 1/4" thick outer structural tubing
• 3.5 mm thick cross tubes
• High-clearance bends
• Adjustable pivot blocks for camber
• Preinstalled double-bonded bushings
• UV-resistant powder coat
• Lifetime warranty

Thick-Wall Strength

Three tube sizes do different jobs: 38 mm main tubing, 1/4" outer structural tubing and 3.5 mm cross tubes. The result is an arm that resists bending from rocks, stumps and hard landings.

Longer Wheelbase, Bigger Tires

Moving the ball joint back stretches the wheelbase for more stability and opens room for bigger tires. Pair them with forward offset front A-arms to fit up to 34" tires.

Camber Your Way

The pivot blocks come set to stock, but you can adjust camber for a lift or heavy loads to reduce tire wear.

Bushings Already In

Double-bonded automotive-style bushings come preinstalled, so you skip the hardest part of an A-arm swap.

Who It's For and What Pairs Well

For HD11 and MAX HD11 owners running bigger tires or rough terrain. Pair with forward offset front arms in Defender A-arms, Defender axles and CVs and Defender suspension.

FAQ

Do I need a lift for 34" tires?

No, when paired with forward offset A-arms.

Can I adjust camber? Yes, with the adjustable pivot blocks.

Why Offset Arms Instead of a Lift?

A lift raises the whole machine and changes how it handles. Offset arms make room for bigger tires by moving the wheels, not raising the body, so the Defender keeps a lower center of gravity and stays stable on side hills and with heavy loads. For many owners, offset arms plus slightly larger tires are the best mix of capability and handling.

Planning Your Build

• Pair with forward offset front A-arms to make room for 34" tires
• Check axle angles and consider stronger axles when running big tires
• Re-check camber after the install, especially if you carry heavy loads
• Plan an alignment once everything settles

Care Tips

• Inspect bushings and ball joints at each service
• Check pivot bolt torque after the first few rides
• Touch up chips in the powder coat to prevent rust

Are bushings included? Yes. Double-bonded bushings come preinstalled.

What's the warranty? A lifetime warranty on the A-arms.

Built for Real Abuse

Rear arms on a Defender take hits from logs and rocks the front wheels already climbed over, plus the weight of whatever is in the bed. The high-clearance bends lift the arms away from obstacles, and the thick-wall tubing resists bending when you do make contact.

Can I use them without forward offset arms? Yes. They add rear tire clearance and stretch the wheelbase on their own; the 34" tire fitment applies when paired with forward offset front arms.

Installation Notes

Support the machine, remove the rear A-arms and install the new arms with bushings already pressed in. Set camber and torque all bolts at ride height.
