Pro-Tek SAB-20 – Chain Adjuster Two Bolt Repair Kit


(SAVE Now!)

as of 06/24/2024 (Details)

This Pro-tek SWING ARM BUDDY double repair kit (Pro-tek Part No. SAB-20) replaces 2 chain adjuster bolts after they seize and break off in the swing arms of most off road motorcycles. During normal cleaning and/or operating in moist environments, water enters and migrates to the rear of the swing arm causing the bolt to rust and seize. Consequently, at the next chain adjustment interval, the bolt can break off in the swing arm. This is becoming an increasingly common problem with today's motocross, street and enduro bikes. Rather than removing the swing arm from the bike, the SWING ARM BUDDY will allow the average rider to fix the broken stud in approximately 10 minutes without the expense of a machine shop, normally required for this repair. It comes in two distinct kits. A SAB-10 single kit includes one 3/8" extractor drill bit and one special thread fitting. A SAB-20 double kit includes one 3/8" extractor drill bit and two special thread fittings.
