Kenny Hubbard showing off his new Mark Williams floater setup paired with his fabricated housing. Cars continue to get faster and heavier and one huge upgrade for both safety and consistency is a floater axle setup. We are seeing a lot of great results as some of these small tire cars convert from fl**ged axles. At the weight and 60’ times of these modern class cars they experience fl**ge axle distortion which can create not only a chance for breakage but will distort the axle and cause erratic 60’ time differences from pass to pass and even aborted pass situations. Switching to a floater helps remove that stress from where the fl**ge meets the axle so you have a wheel that moves without deflection from the axle for smoother power application. Customers with big power commonly report faster and more consistent short times and less aborted runs when upgrading to a floater and often report “I didn’t even realize I was having this issue previously”. Safety, durability, and tuning benefit! Mark Williams offers floater kits and axles for 5x4.75, 5x5, and 5x5.5 bolt patterns in both steel and carbon rotor options and as well as Mark Williams and TBM Brakes

A best kept secret! The Mark Williams pinion support kits are used by many of the best builders and third member setup folks of all time. These 7075 billet aluminum pinion supports are strong but also known for their efficiency and low friction. The reason we offer these as a kit is because we preset the pinion spacer for you taking the guess work out of using a non optimal crush sleeve or a less than ideal shim able spacer. We install bearing races and bearings and machine the spacer to exact specs so you can have a low friction pinion setup without the guess work. If you check on our site we offer pinion supports for 9”, 9.5”, and 10” gear sets and also for taper / taper bearing combinations, taper / roller bearing combinations, and dual ball bearing offerings. We also offer in steel and ceramic bearings. Every car and its intent and needs are unique from power level to efficiency needs, we can help steer you in the right direction if you’re wondering what’s best for you. This is another crucial part of what makes Mark Williams third members so smooth and “slippery” and an example of Mark Williams going the extra mile for top quality results!
