Extended heavy-duty steel links. In addition to being virtually indestructible, steel links add valuable weight to the lowest part of your truck for improved anti-rollover stability. Links come assembled and ready to mount with rod ends and steel hollow balls. Includes 4x55 mm front lower links (2), 4x48 mm front upper links (2), and 4x74 mm rear upper and lower links (4). Does not fit standard TRX-4M.
