What does a rear differential cover do? In addition to providing access for changing gear lube, differential covers help dissipate heat that can damage differentials, and they protect gears from contaminants like dirt and water, as well as rocks and other large obstacles encountered when off-roading. SPELAB aluminum differential covers are designed to protect your ring and pinion from impact and help cool your gear oil for prolonged bearing life. Made from high-strength, heat-treated aluminum to withstand direct hits.

It is better to adjust the free travel of the clutch pedal to less than 50% of the free travel of the two pedals of the brake Correct operation, smooth start, avoid impact start, try to reduce sudden brake, sharp turn, etc., so as to keep it in good technical condition FAQ Q1: How does the SPELAB rear differential cover prevent overheating of the differential? A1:The SPELAB rear differential cover features an advanced heat sink design that maximizes heat dissipation by increasing the contact area with the surrounding air. This design helps to reduce the temperature of the gear oil, preventing the differential from overheating during heavy use, such as towing or off-roading. By maintaining optimal operating temperatures, the cover helps to extend the life of the gears and bearings. Q2: What benefits does the internal diversion groove offer in the SPELAB rear differential cover? A2:The internal diversion grooves within the SPELAB rear differential cover help optimize oil flow throughout the differential. These grooves direct the gear oil to the critical areas, ensuring consistent lubrication of the gears and bearings. This enhanced oil flow minimizes friction, reduces wear, and improves the overall efficiency of the differential, which is crucial for performance and longevity. Q3: Is the SPELAB rear differential cover compatible with off-road applications? A3:Yes, the SPELAB rear differential cover is designed to...
