The JackJaw peg puller jaws are made from case hardened steel and will offer years of service. However, metal against metal will invariably wear over time and the jaws may need replacing. It’s quick and simple to replace the jaws on your JackJaw peg puller. Simply remove the bolts securing the jaws, remove the circlip at the rear of the jaw pivot, and the jaws can be removed and replaced. Peg puller jaws come in a set of 4 as all peg pullers require 2 jaws on either side to give the peg puller its tremendous gripping power.
