The 2026 Can-Am Defender HD11 combines a 95-horsepower three-cylinder engine with the comfort, cargo capacity, and utility features that have made the Defender a popular platform. For owners who want to take the new HD11 Limited into rougher terrain, Cedar Suspension Co. has developed a mid-travel suspension system that adds width, stability, clearance, and room for larger tires.
The CSC Can-Am Defender HD11 Mid-Travel Suspension Kit transforms the Defender into a 72-inch-wide machine with an equal hub-to-hub width at both ends, high-clearance front A-arms, extended axles, upgraded steering components, and clearance for tires up to 35 inches.
The system starts at $4,999.99 and can be configured with different shocks, ball joints, axles, and powder-coat finishes. That flexibility allows owners to tailor the kit to their intended use, performance goals, and budget.

Why Widen the Can-Am Defender HD11?
The Defender HD11 measures approximately 65 inches wide in its factory configuration. That width works well for a broad range of utility and recreational riding, but owners who regularly encounter rough, uneven, or off-camber terrain may benefit from a wider stance.
Increasing track width creates a more planted platform through corners and across side slopes. The additional stability can be especially valuable in a tall, fully enclosed Defender carrying passengers, tools, recovery equipment, or camping gear.
CSC’s mid-travel system adds 3.5 inches per side at the front and 4.5 inches per side at the rear. Although the extensions differ, both ends of the Defender measure approximately 72 inches hub to hub after installation.
A 72-Inch Square Stance
The factory Defender does not have equal front and rear hub-to-hub measurements. CSC accounts for that difference by extending the rear suspension one inch farther per side than the front, creating what is commonly called a square stance.
The finished layout allows owners to use the same wheel offset at all four corners without rear wheel spacers. Matching wheels simplify wheel selection and allow complete tire-and-wheel assemblies to be rotated from front to rear.
More importantly, the wider footprint can improve driver confidence through corners, across ruts, and on uneven trails where the machine is constantly shifting from side to side.

Clearance for Tires Up to 35 Inches
Larger tires can increase ground clearance, improve traction, and help a UTV roll over rocks, ledges, washouts, and deep ruts. CSC designed its Defender HD11 mid-travel system to allow for tires up to 35 inches tall.
Actual clearance depends on the tire’s measured dimensions, wheel width, wheel offset, suspension setup, and steering angle. Tires carrying the same nominal size can vary considerably in actual height and section width, so some 35-inch combinations may experience rubbing. CSC recommends high-offset wheels to maximize clearance.
More Than Extended A-Arms
A proper mid-travel conversion requires the suspension, steering, and driveline components to work together throughout the vehicle’s range of motion. Depending on the selected configuration, the CSC HD11 system includes:
- High-clearance front A-arms
- Extended rear suspension components
- Extended axles
- Upgraded tie rods
- Grooved Delrin suspension bushings
- Integrated steering stops
- Grease fittings on the A-arms
- Required installation hardware
The extended axles accommodate the additional suspension width without relying on axle spacers. Upgraded tie rods provide the length required by the wider front suspension, while the integrated steering stops control steering travel and retain the intended steering geometry.
CSC uses grooved Delrin bushings to distribute grease around the bushing surface. Preinstalled grease fittings make routine suspension service more convenient and help maintain smooth movement.
High-Clearance Front A-Arms
Added width alone does not make a suspension system more capable in technical terrain. Control arms that hang low can still drag across rocks, roots, and the edges of deep ruts.
CSC’s arched front A-arms create more clearance beneath the suspension components. Combined with larger tires, the high-clearance design helps the Defender negotiate rocky trails and deeply rutted terrain without unnecessarily sacrificing clearance at the arms.
Built for the Weight of the Defender HD11
The Defender HD11 is a substantial vehicle, particularly in its fully enclosed Limited configuration. Once passengers, cargo, accessories, recovery equipment, and larger tires are added, the suspension must manage considerably more than the machine’s published dry weight.
As detailed in our Cedar Suspension Co. company profile, CSC develops and tests its products in the demanding terrain surrounding Cedar City and Southern Utah.
The company laser-cuts the primary components for the HD11 kit from specialty steel that CSC says is 30 percent stronger than 4130 chromoly. Critical machined components are made from 4130 chromoly.
The suspension components incorporate internal and external gusseting along with double-pass welds in critical stress areas. Each kit is hand TIG welded in Cedar City, Utah.
Those construction details are important because longer arms create additional suspension leverage, while taller and heavier tires can increase loads throughout the steering, suspension, and driveline systems.

Factory Shocks or SDi Upgrades
The CSC mid-travel kit can be installed with the Defender’s factory shocks, providing a lower-cost entry point into the wider suspension system. However, the original shocks were tuned around the factory suspension geometry. Extending the arms changes the leverage applied to the shocks, and larger tires can add unsprung weight.
CSC offers two SDi shock upgrades for owners seeking greater suspension control:
- SDi Terrain Master 2.1 shocks for the Can-Am Defender HD11 provide upgraded damping, body control, and bottoming resistance for rough-terrain use.
- The premium SDi E-CLIK Active Pro suspension for the Can-Am Defender HD11 adds electronically adjustable damping that can respond to changing terrain, speed, steering input, and vehicle movement.
Owners can retain the factory shocks, select one of the SDi upgrades offered through CSC, or source another compatible shock solution.

Configurable Ball Joints and Axles
CSC also allows customers to select ball-joint and axle options when configuring the kit. These choices make it possible to match the suspension components to the way the Defender will be used.
A recreational trail machine may not require the same component combination as an HD11 running 35-inch tires, carrying substantial additional weight, or regularly encountering demanding rock and desert terrain. The available options let owners prioritize the upgrades that best fit their intended use.
Powder-Coat Options
The suspension can be ordered with different powder-coat finishes, allowing owners to coordinate the components with the Defender’s bodywork, cage, wheels, or other accessories.
Powder coating also provides a durable protective finish for parts exposed to rocks, mud, water, and trail debris. Available colors and pricing may change, so customers should review the current selections on the CSC product page.
Starting at $4,999.99
The CSC Can-Am Defender HD11 Mid-Travel Suspension Kit starts at $4,999.99. The final price depends on the selected shocks, ball joints, axles, and powder-coat finish.
This configurability allows customers to choose the components and finish that fit their performance goals and budget. Buyers can review the current options on the CSC HD11 Mid-Travel Suspension Kit product page or contact Cedar Suspension Co. for help configuring the system.

Fitment and Installation
CSC currently lists the kit for 2025-and-newer Can-Am Defender HD11 Limited models equipped with Smart-Lok. Owners should confirm the model, trim, and drivetrain requirements with CSC before ordering.
The mid-travel system uses the Defender’s factory suspension mounting locations and does not require cutting the chassis. Although it is a direct bolt-on conversion, installation involves replacing major suspension, steering, and driveline components.
CSC strongly recommends installation by a qualified shop or technician familiar with UTV suspension systems. Proper axle installation, brake-line routing, steering setup, fastener torque, wheel alignment, and post-installation safety checks are critical to performance and component life.
