This is an optional Mugen 70mm Front Shock Spring Set, and is intended for use with the Mugen MBX7 1/8 scale nitro buggy. These 1.6 springs provide a softer feel to help tame the buggy. Many racers like running these springs on more wide open bigger tracks in combination with the black springs on the rear. The stock silver 1.5 springs are preferred on tracks with more jumps as they help the buggy to launch in the air better.
