Shock Therapy - Polaris RZR Limit Strap Kits

Shock Therapy Billet Front Fork Limit Strap Kit

A great addition to the RZR Pro R/RZR Turbo R front suspension system, highly recommended for upgraded tires and wheels.

• Stop clunk: Eliminates the metal-on-metal clunking sound caused by shocks dropping out when upgraded to bigger tires and wheels. Factory internals are insufficient to arrest extension with aftermarket upgrades.
• Save the shock: Prevents damage from excessive clunking. Over time, repeated impact can cause the shock shaft nut to shear off at the washer, allowing the piston to pop off and the shaft to exit the shock entirely.
• Completely adjustable: Shock Therapy limit straps are adjustable at the shock body mount to account for natural strap stretch. Straps typically stretch 1 to 1½ inches after 200-300 miles of use. Adjustment allows precise length control without sacrificing suspension travel.
• Bolt-on installation: Patented billet aluminum upper clamp attaches directly to the shock head without welding. Clamps are clock-able to avoid body panels, radiator hoses, and other clearance obstacles.
• Minimize leverage: Straps remain parallel to the shock for optimal geometric alignment and extended strap life. Clevis design positioned close to the shock works on more models with less system leverage.
• Prevent strap interference: Patented extension tether design keeps slack in position, preventing the strap from catching on sway bar links, brake lines, or other components during suspension extension.
• Save CV joints: Limit straps prevent over-extension beyond maximum CV angle, reducing wear and potential failure of the joint.

Important Notes:

• Limit straps are a wearing item with a lifespan similar to brake pads and will need replacement when worn out.
• Rear shock kit not yet available for Turbo R models.
• Rear Pro R Kit features a new Lower Mounting Bracket design for outside shock mounting. The Upgrade Kit is available for customers with previous rear limit strap kits who wish to update to the newest design.
