Browse DGT Agri's range of independent rear suspension (IRS) bush kits for ATVs and UTVs, covering popular makes including Polaris, Can-Am, Kawasaki, Yamaha, Honda, Arctic Cat, and more. The bushes in an IRS system take constant loading and flex on rough terrain - worn or cracked bushes are a common cause of rear-end clunking, imprecise handling, and accelerated wear on surrounding suspension components.
