Take your TRX-4Mto the next level by replacing the standard suspension links with these heavy-duty steel links. In addition to being virtually indestructible, steel links add valuable weight to the lowest part of your TRX-4M for improved anti-rollover stability. Links come assembled and ready to mount with rod ends and steel hollow balls. Includes 4×53 mm front lower links (2), 4×46 mm front upper links (2), and 5×56 mm rear upper and lower links (4).
