1. Maxima Suspension Grease: Best Overall
Maxima Suspension Grease is formulated specifically for ATV and motorcycle suspension components. Based on owner feedback and the spec sheets, it provides superior adhesion and water resistance, making it ideal for riders who frequently encounter mud, rain, or stream crossings. Its synthetic base and extreme pressure additives meet or exceed NLGI #2 standards, ensuring consistent performance under heavy loads.
However, this grease is more expensive than general-purpose alternatives. If you ride only on dry trails and do not submerge your ATV, a less water-resistant grease may suffice. We recommend this for serious off-roaders who prioritize suspension longevity.
- Synthetic formula designed specifically for suspension and linkage bearings
- Excellent adhesion and water resistance for wet and muddy conditions
- High extreme pressure (EP) rating protects against shock loads
Pros: Outstanding water resistance and longevity; Works well in high-load suspension applications
Cons: Higher price point compared to multipurpose greases
2. Bel-Ray Waterproof Grease: Best Waterproof
Bel-Ray Waterproof Grease is a staple among ATV owners who ride in wet environments. In our evaluation of manufacturer specs and owner reviews, it consistently holds up against water washout better than many competitors. The lithium complex thickener and EP additives provide reliable lubrication for suspension pivots and bearings.
One real limitation is that it becomes noticeably thicker in sub-freezing temperatures, which may increase initial resistance. If you ride in extreme cold, consider a synthetic grease with lower viscosity. Otherwise, this is a solid choice for general ATV suspension maintenance.
- Lithium complex formula with excellent waterproofing properties
- Meets NLGI #2 and ASTM D4950 GC-LB standards
- Suitable for suspension bushings, ball joints, and chassis points
Pros: Exceptional water resistance even in pressure washing; Wide operating temperature range
Cons: Can be stiff in very cold weather
3. Lucas Oil Red 'N' Tacky Grease: Best Value
Lucas Oil Red ‘N’ Tacky Grease is a favorite among budget-conscious ATV owners. Based on our research of owner feedback and the spec sheet, it offers strong adhesion and corrosion protection, making it suitable for suspension joints that are not constantly submerged. The red color helps with visual application tracking.
However, its water resistance is only moderate. If you frequently cross deep water or pressure wash your ATV, this grease may wash out faster than waterproof options. We recommend it for dry-weather riders or as a general shop grease.
- High tack formula clings to suspension components
- Excellent rust and corrosion protection
- Affordable price point for large tubs
Pros: Very tacky, stays in place on vertical surfaces; Great value for the quantity
Cons: Not as water-resistant as dedicated waterproof greases
4. Mobil 1 Synthetic Grease: Best Synthetic
Mobil 1 Synthetic Grease is engineered for demanding automotive and industrial applications. In our comparison of spec sheets, it offers outstanding thermal stability and resistance to breakdown under high loads, which can benefit aggressive ATV riders who push their suspension hard. Its synthetic base resists water washout better than conventional greases.
That said, its price is significantly higher than many ATV-specific greases. For riders who ride occasionally or in mild conditions, this grease may not provide noticeable benefits. We recommend it for competitive riders or those who operate in extreme temperatures.
- Full synthetic PAO base for extreme temperature stability
- Excellent shear stability and oxidation resistance
- Recommended for high-speed and high-load applications
Pros: Wide operating temperature range; Long service life under severe conditions
Cons: Premium price; may be overkill for casual riders
5. Valvoline DuraBlend Grease: Good All-Rounder
Valvoline DuraBlend Grease is a synthetic blend that offers a middle ground between cost and performance. Based on owner feedback and the spec sheet, it provides decent water resistance and EP protection thanks to its moly content. It performs well in ATV suspension bushings and ball joints under normal riding conditions.
However, some users report that it is less tacky than pure lithium greases, which can lead to dripping or slinging in high-speed applications. Also, prolonged storage may cause oil separation. We recommend it for riders who want a modest upgrade from conventional grease without spending top dollar.
- Synthetic blend with molybdenum disulfide for added EP protection
- Good water resistance and mechanical stability
- Adaptable for chassis and suspension applications
Pros: Moly additive helps with extreme pressure; Reasonable price for a synthetic blend
Cons: Not as tacky as some competitors; May separate in long-term storage
6. LubriMatic Extreme Pressure Grease: Budget Pick
LubriMatic Extreme Pressure Grease is a budget-friendly option that meets basic NLGI #2 standards. In our evaluation of owner reviews, many ATV owners use it for routine greasing of suspension fittings with satisfactory results for light trail riding. It provides adequate EP protection for normal loads.
However, its water resistance is limited, and it can wash out quickly in wet conditions. Additionally, it may not hold up under the high shock loads of aggressive riding. We recommend this grease only for casual riders who avoid deep water and who want to save money.
- Affordable extreme pressure grease for general use
- Good rust and corrosion inhibitors
- Available in convenient cartridges and tubs
Pros: Very low cost per ounce; Suitable for light to moderate use
Cons: Water resistance is below average; Not recommended for submerged or high-load suspension
7. Sta-Lube Waterproof Marine Grease: Specialty Pick
Sta-Lube Waterproof Marine Grease is designed for marine applications, but some ATV owners use it for suspension components that are frequently underwater. In our research of spec sheets, its aluminum complex formula offers superior water resistance and corrosion protection, making it a viable choice for mud boggers or riders in coastal areas.
However, this grease is very stiff at low temperatures, making it hard to apply with a grease gun in winter. It also lacks the high-speed performance of synthetic greases. We recommend it only for riders who prioritize water resistance above all else and who ride in warmer climates.
- Aluminum complex thickener for extreme water resistance
- Contains rust and corrosion inhibitors for saltwater environments
- High dropping point suitable for high-temperature applications
Pros: Exceptional water resistance, even in salt water; Good for submerged suspension components
Cons: Stiff and difficult to pump in cold weather; Not optimized for high-speed bearings
Frequently Asked Questions
What type of grease should I use for ATV suspension?
For ATV suspension, use a NLGI #2 grease with good water resistance and extreme pressure (EP) additives. Lithium complex or synthetic greases are preferred. Avoid general-purpose greases that may wash out easily.
Can I use automotive grease on my ATV suspension?
Yes, many automotive greases meet the same NLGI #2 standard. However, ATV suspension often faces more water and mud exposure, so a waterproof or marine grease may be more suitable. Check the grease’s water resistance rating.
How often should I grease my ATV suspension?
It depends on riding conditions. For typical trail riding, grease every 10-20 hours of operation or after every wash. If you ride in mud or water, grease more frequently, such as after every ride.
Is synthetic grease better for ATV suspension?
Synthetic greases generally offer wider temperature ranges, better oxidation resistance, and longer life. They are beneficial for aggressive riders or extreme conditions, but for casual use, a quality lithium complex grease is sufficient.
Can I mix different greases on my ATV?
Mixing greases with different thickeners (e.g., lithium and aluminum complex) can cause incompatibility, leading to separation or loss of lubrication. It is best to stick with one type or thoroughly clean components before switching.
Our Verdict
After researching and comparing specs, standards, and owner feedback, our top pick is Maxima Suspension Grease for its dedicated ATV suspension formulation, outstanding water resistance, and EP protection. For a more budget-friendly option, Lucas Oil Red ‘N’ Tacky Grease offers great value for dry-weather riders. Choose based on your riding conditions and priorities.
