This rear axle breather will stop lube from being flung out of rear axle housing. Allows "breathing" of rear axle assembly. 7/16"-20 thread. Polished!
Install with thread sealant or Teflon tape. Can be used on various applications with appropriate plumbing components.
This driveshaft safety loop holds the drive shaft in place in case of universal joint failure. Made from 2" x 1⁄4" hot rolled steel with grade 5 bolts. Bolt-on installation.
Universal rear sway bar fits frame up to 45" wide, which makes it ideal for many 1928-1948 street rod applications. Both the 1-1/4" diameter shaft and the 2" O.D. weld-in frame tube can be shortened for narrower frames. The billet aluminum arms are not splined - they are held on by drilling the shaft and inserting a bolt all the way through the end of the shaft.
Includes bushings, 3/8" adjustable rod ends and all hardware. Welding required.
Red Line Shockproof synthetic gear oil is designed for heavily loaded racing and street differentials that see heavy shock loading. It contains a unique solid dispersant that cushions gear teeth to help prevent breakage. Red Line Shockproof gear oil provides the protection of a 75W250 with the fluid thickness properties of a 75W90.
Ideal for use in sprint, midget, and dirt late model differentials as well as in rear ends using spools or lockers.
- Fully-synthetic gear oil formula created from polyol ester base stocks offers excellent lubrication under extreme conditions
- High viscosity-index to provide relatively constant viscosity and film thickness with varying temperature change
- Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
- Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oil
- Exceed API GL-5 specifications
- Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
- Not recommended for most synchro applications due to the product's extreme slipperiness
