Pro Touring Street Floater Kits
When it comes to hardcore corner carving, piston knock-back can be a big time issue with braking. To combat this, Strange Engineering offers an optional Pro Touring Street Floater kit, which was a joint effort with Wilwood Brakes. Imagine if you will, traversing through a series of turns, followed by a long straightway. As you setup for the next turn and get on the brakes, you have no pedal pressure and have to start pumping the pedal to get it back; not exactly the most secure feeling in the world. To combat this, Strange Engineering offers a complete Pro Touring Street Floater kit that comes with chrome-moly spindles, chrome-moly hubs, 35-spline drive plates, and will work with 3- and 3 ½-inch diameter tubes. This package will require a quality shop to machine and fit the floater assembly, but it's well worth it by keeping the brake feel consistent.

Pro Touring Street Floater Kits 2/22
Pinion Races Installed Without 3/22

8. Pinion races are then installed without the use of any shims.

Measured For Pinion 4/22

9. Using a depth mic, we measured for pinion depth, installed the pinion, and put preload on it; the recommended depth is 3.125-inch, measuring from the saddle bore to pinion.

Installed Rear Pinion 5/22

10. We then laid a strap across the carrier bearing saddles, which is subtracted from the final depth; our application required 0.018-inch shims. From there we installed the rear pinion brace.

Measure Crushed Wire To Get Shim 6/22

11. To set the front pinion bearing preload we used a 0.090-inch thick soldering wire on the pinion shaft, where the preload shims would be installed. Once the pinion is installed, we used an in-lb torque wrench to get a 20-25 in-lb reading. From there, we removed the pinion and measured the crushed wire to size up the correct shim pack. Ours showed that 0.050 was needed.

Corresponding Caps Are 7/22

12. To eliminate any confusion, the corresponding caps are marked to help ensure proper installation.

Torque Caps To Measure Proper 8/22

13. To measure for proper backlash, we first torque the caps to 90 ft-lb; ours measured 0.009, which is well within the recommended 0.004-0.010 tolerances.

Applied Grease Paint On Ring Gear 9/22

14. In order to determine proper pinion depth, we applied grease paint on the ring gear teeth. Once on, we spun the gear with a drill to reveal the contact patch.

Install Pinoin Seal And 10/22

15. Up next, install pinion seal and yoke for the final time.

Carrier Set In For Final 11/22

16. From here, the carrier can be set in for the final install and the lock tabs will keep the adjuster from working its way loose.

Permatex Blue Sealer Applied To 12/22

17. Permatex Blue sealer is applied to the case and the differential cover is set into place and tightened. No gaskets are necessary.

Wheel Studs Bolted Onto 13/22

18. Wheel Studs were then bolted into the flange with a small amount of red Loctite and torqued to 90 ft-lb.

Axle Bearings Pressed 14/22

19. Axle bearings can be pressed on at this time using no more than 100 psi of pressure.

Axle Locking Into Retainer 15/22

20. Once the axle is set, it’s then locked into place with the retainer plate to complete the build. CHP
