    • Complete kit installs easily in about 30-45 minutes
    • Fits 2018 & newer Polaris RS-1

    • Made in USA

The Polaris RS-1 has a rear trailing arm suspension with radius rods similar to the RZR XP 1000 & XP Turbo. This design provides camber changes throughout the suspension travel to improve handling. The stock Polaris radius rods are mounted to the frame in a weak single- shear fashion, with a separate sheet metal stiffener plate added to the rear. 

This product is a patent-pending radius rod mount design to upgrade the stock RZR's radius rod suspension from a single-shear radius rod mount to a much stronger double-shear design. The double-shear radius rod mount replaces the original stiffener plate and features additional frame mounting points (at both the top and bottom) to securely mount the double-shear plate directly to the frame, without relying only on the four radius rod bolts for mounting. This double-shear mount creates a second frame mount for the radius rods that 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 strength of the radius rod mounts, eliminating damaging flex and stopping the problem of deforming, elongating (egging-out) & cracking around the radius rod mounting holes in the RZR frame. Thunderhawk's double-shear design provides a major benefit by increasing frame and suspension strength, and is superior to any other rear radius rod plates or cages. Thunderhawk's patent-pending double-shear mounting is the only engineered solution that actually improves the frame design and strengthens the frame to handle the suspension forces encountered in real-world RZR driving conditions, whether racing or just for regular trail- riding.

The double-shear radius rod mount features a differential fluid service access hole and is designed to fit with Polaris-brand and most aftermarket bumpers or rear roll cages that use the Polaris-style mounts. Another nice feature offered by The double-shear design is the fact that this plate is mounted directly to the frame (independent from the four radius rod bolts) making rear suspension work much easier and allowing the radius rods to be removed and re-installed easily. Anyone who has removed their radius rods has discovered what a pain it can be to install the radius rods with the stock set-up.

Whether you are riding wooded trails, desert, or sand dunes, you can experience frame damage at the radius rod mounts, even at slower speeds. We can confidently say that this Double-Shear Plate will benefit almost all RS-1's by strengthening this weak area of the frame. The double-shear radius rod mount installs in about 30-45 minutes. Durable black powder-coat finish. Does NOT fit RZR XP 1000, XP Turbo, or XP Turbo-S (72" wide model). Made in the USA.

* NOTE: This double-shear plate will NOT fit any RZR equipped with Polaris #2879523 high-clearance radius rod kit, or the Polaris high clearance radius rods from the High Lifter or Trail & Rocks RZR models.

Fast and efficient!
Color: Upgrade Black, Size: Rechargeable
These are a very nice set. Our other pair started grinding the salt and pepper as soon as you flipped it over and made a mess. This set here you have to push the button first. Also it is faster at grinding. Recommend!

Who knew laziness could be so rewarding?!
Color: Upgrade Black, Size: Rechargeable
Super happy with this purchase. With the press of a button I have freshly ground salt and pepper...makes a big difference in taste. I appreciate the lighted bottoms which make it easier to see the quantity being dispensed. The charge has lasted a full month so far with near daily use. They are attractive on my counter and the tray they sit in collects the loosened remnants and is very easy to clean. May give as gifts this year!

Poor Grind Mechanisms
Color: Upgrade Black, Size: Rechargeable
Salt grinder fell apart in 6 weeks. The item looks nice, but the grind settings on both the salt and pepper did not yield truly different grind. They always came out the same size, regardless of setting. About 5 weeks in, the clear plastic bottom came off of the salt grinder. I wasn't even using rock salt, just coarse salt. I could not get the piece back in. Then, the entire grind assembly came out as I was cooking. This item did not even get daily use. I purchased a different brand several years ago, I wish I had purchased that one again. I thought I was getting a good deal based on reviews. **UPDATED 9/19** Seller made reasonable accommodations to make it right. Very pleased with how this was handled. Stars reflect customer service,

Color: Upgrade Black, Size: Rechargeable
very well made and super easy to fill and clean. great price and the dial for coarseness is great. i have arthritis and can no longer do the twist version of cracked pepper and salt. This makes it so much easier to use. The light is a nice feature.
