The RipTide APS Magnum Bushings are designed for trucks that feature a slightly larger bushing seat. The Magnum performs similar to the Chubby by providing a stable and predictable lean with a solid level of rebound to set your trucks back to centerline.
Try combining the APS Magnum with an APS Canon bushing. This application is ideal for riders looking for stability at higher speeds but still maintaining a predictable lean for spread out turns.
When tuning your Magnum Bushings, RipTide recommends tightening the kingpin nut to the point where it is difficult to turn the bushing in the bushing seat by hand. Use a flat washer to lower resistance and a cupped washer for higher resistance. The APS does not change much when you tighten the kingpin nut past snug.
The APS Magnum measures .60" tall with a slightly larger bushing foot making them perfect for trucks that feature a slightly larger bushing seat such as Paris, Caliber, Kahalani Cast, and Gullwing Charger 2 (Boardside).

RipTide describes their APS Formula as follows: "As the name implies, this compound is very lively and offers higher rebound with lots of control and lean. For the same durometer, the APS will turn 10% to 15% more than the same durometer of other brands." This formula produces a very stable feel near centerpoint yet requires very little lean effort to produce desired turns.
