Before studding, first determine the type of riding style which best describes you (trail, aggressive trail, competition racing). Also consider the amount of horse-power your machine produces. Under-studding will cause excessive wear or damage studs, over studding will not allow studs to penetrate, causing them to float.

For best results the studs should be 1/4" - 3/8" above lug of your track. The studding pattern is determined by the number of studs that are being installed. Choose a pattern that will obtain the greatest number of penetration lines. Remember: the centre belt has the greatest effect on acceleration; the outside belt has a greater effect in cornering.

Stud patterns shown are just suggested patterns: you can change them to suit your needs.


1. Work off the top of your track, near rear mud flap. (Pulling two rear suspension bolts on the tunnel greatly helps to provide more working area.)

2. Using the original ACS aluminum washers*-lay out a pattern on the track.

3. Using ACS track cutter, drill out holes as per lay out of washers. (ACS track cutter tool cuts cleanly and leaves the perfect size hole without overheating track.)

4.a) ACS PUSH THRU STUDS Insert the stud through the track, slip washer over stud, install lock nut and tighten until the stud's shoulder bottoms out on the washer. Locktite is not needed when nyloc nuts are used.

4.b) ACS T-NUT PULLER Insert in hole and pull T-nut in place. Hold from back and remove tool. Insert stud through washer and put a small drop of red locktite on threads of stud and tighten in place.

5. Install ACS tunnel protectors to prevent studs from damaging tunnel.
