STRONG, DOUBLE-SHEAR UPGRADE
This Thunderhawk double-shear radius rod upgrade kit replaces the original 4-hole stiffener plate and features additional frame mounting points (at both the top and bottom) to securely mount the Thunderhawk double-shear plate directly to the frame. Thunderhawk's double-shear plate creates a second frame mount for the radius rods which is securely attached directly to the frame to support the rear of the radius rods. With the radius rods now supported on both the front (through the stock frame) and the rear (through the Thunderhawk double-shear plate), we have doubled the shear strength of the radius rod bolts and eliminated shear load deflection (flex) of the radius rod bolts. This design upgrades the stock RZR from a weak single-shear radius rod mount to a much stronger double-shear design and eliminates the problem of deforming, elongating (egging-out) & cracking around the radius rod mounting holes in the RZR frame.
WHY CHOOSE THUNDERHAWK PERFORMANCE ?
Thunderhawk Performance was the first company to identify the weakness of the single-shear Polaris radius rod design and developed this tested & proven double-shear upgrade for the RZR. This is not just some "dress-up" part for the RZR. Thunderhawk's patent-pending double-shear radius rod upgrade is the only engineered solution that actually improves the frame design and strengthens the frame to reliably handle the suspension forces encountered in real-world RZR driving conditions, whether for racing or just for every-day trail-riding.

Fitment and Installation
FITS :
- 2014 - 2015 Polaris RZR XP 1000
SPECIAL FITMENT NOTES
- Fits with stock, and most aftermarket radius rods -
- The Thunderhawk Double-Shear Radius Rod Upgrade Kit feature direct
frame mounting, so fitment of these parts are affected by the width of
the radius rods (where the bolt passes through at the frame end). The
factory-installed radius rods on the RZR XP measure 1 3/8" wide.
Thunderhawk Performance makes this Double-Shear Plate to fit this stock
dimension. There are dozens of aftermarket radius rods which may or may
not be built to the stock 1 3/8" width. To assure that you do not have
any fitment issues, you MUST verify the measurement of
your radius rods (see photos above) before ordering.
- Does NOT fit with aftermarket bumpers using four-bolt radius rod plate for lower mounting (see photos above)
