A RZR actually needs two different kinds of grease, not one all-purpose tube: CV joints want a soft, moly-heavy grease that squeezes into a tight boot, while wheel bearings, ball joints and tie rods want a stiffer NLGI Grade 2 multipurpose or EP grease. Waterproofing matters more here than on a street car, since RZRs regularly cross mud and water. These ten are real, currently sold greases covering both jobs, from genuine Polaris OEM to full-synthetic upgrades.

The picks, in detail
Polaris Premium All Season Grease (OEM #2871423, 14 oz)
The factory-spec grease Polaris itself sells for RZR wheel bearings, ball joints and tie rods — water-resistant and rated for the extreme pressure and temperature swings of off-road use.
- Genuine Polaris OEM part #2871423
- Water-resistant formula
- Rated for snowmobile, ATV and RANGER/RZR applications
- Exactly what Polaris specs for these components, no guesswork
- Widely stocked at Polaris dealers and Walmart
- Not sold as a dedicated CV-joint grease — pair with a moly grease for CV boots
Lucas Oil Red N Tacky Grease (10005, 14 oz tube)
A moly-fortified, tacky red grease widely recommended on RZR forums for CV joints and general chassis points — it stays put on a joint that moves constantly.
- Rust and oxidation inhibitors
- Strong resistance to spray-off and water washout
- Excellent mechanical stability
- One of the most-recommended CV joint greases on RZR forums
- Inexpensive for the tub/tube size
- Lithium-complex base, not full synthetic
Mobil 1 Synthetic Grease (13.4 oz tube)
A full-synthetic red chassis/wheel-bearing grease frequently cited by RZR owners as an upgrade over stock grease for suspension pivots.
- Full synthetic base
- Extended temperature range
- Corrosion protection
- Synthetic base holds up better than lithium grease in heat cycling
- Available at most auto parts stores
- Pricier per ounce than basic lithium greases
Super Lube Multi-Purpose Synthetic Grease with Syncolon PTFE
A PTFE-fortified synthetic grease that stays workable in cold and resists water washout — a common pick for RZR suspension pivots and linkages that see mud and water.
- Syncolon (PTFE) fortified
- NLGI Grade 2
- Translucent, won’t stain
- PTFE cuts friction on pivoting linkages better than plain grease
- Widely available in small tube sizes
- Smaller tube sizes cost more per ounce than bulk automotive greases
Bel-Ray Waterproof Grease (16 oz tub / 14 oz cartridge)
A dirt-bike and powersports staple for wheel bearings and pivots that regularly see water — a common RZR-owner recommendation for wet or muddy riding.
- Waterproof formula
- Designed for off-road powersports use
- Available in tub or cartridge for grease guns
- Purpose-built for the exact wet/muddy conditions RZRs see
- Trusted powersports brand
- Cartridge and tub sizes priced differently — check which you’re ordering
Amsoil Synthetic Water-Resistant Grease (14 oz tube)
A premium full-synthetic grease built specifically to resist water washout, a genuine step up for RZR wheel bearings that see stream crossings.
- 100% synthetic base
- Water-resistant formulation
- High-temperature stability
- Purpose-built water resistance beyond standard EP grease
- Strong reputation in the powersports community
- Costs more than Lucas or Mobil 1 per tube
Royal Purple Ultra-Performance Grease (14.1 oz tube)
A synthetic NLGI Grade 2 grease for bearings and general-purpose chassis points, sold in bulk multi-packs that suit a RZR owner doing several grease points at once.
- Synthetic base
- NLGI Grade 2
- For bearings, U-joints and general use
- Multi-tube case packs bring the per-tube cost down
- Well-known synthetic lubricant brand
- Not marketed specifically for CV joints
Maxima Waterproof Grease (16 oz bottle)
A lithium-complex waterproof grease built for powersports wheel bearings and linkages, rated across a wide temperature range for year-round RZR use.
- Lithium complex base
- Water washout resistant
- -20°F to 560°F rated range
- Bottle applicator makes small, precise applications easy
- Popular in the powersports/off-road community
- Pricier per ounce than automotive-store lithium greases
Valvoline SynPower Full Synthetic Moly-Fortified Grease (14.1 oz cartridge)
A moly-fortified full-synthetic grease built for extreme-pressure, high-load points — a solid CV-joint and ball-joint option in cartridge form for a grease gun.
- Full synthetic, lithium complex base with moly
- Extreme-pressure additives
- Cartridge format for grease guns
- Moly content suits CV joints specifically
- Widely stocked at auto parts chains
- Cartridge only — no small hand-tube option
Lucas Oil Marine Grease (14 oz tube)
A waterproof marine-rated grease worth keeping on hand for RZR bearings after a wet or muddy ride, when washing out standard grease is the bigger risk.
- Marine-grade waterproofing
- NLGI GC-LB certified
- Resists salt and fresh water washout
- Purpose-built for constant water exposure
- Same trusted Lucas Oil formulation family as Red N Tacky
- Marketed for marine use, not powersports-specific
Buying tips
- Use a soft, moly-rich grease (Lucas Red N Tacky, Valvoline SynPower) for CV joint boots — a stiffer NLGI Grade 2 bearing grease can be too firm to fully work into the joint.
- Wheel bearings, ball joints and tie rods want NLGI Grade 2 multipurpose or EP grease meeting NLGI Service Category GC — CV-joint grease is often a softer NLGI Grade 1 and isn’t a substitute.
- If you ride through mud or water regularly, grease wheel bearings after every wet ride, not on a fixed monthly schedule — water washout happens fast.
- Check whether your grease gun takes a cartridge or a bulk tube before ordering; several of these (Bel-Ray, Valvoline) are sold in both formats at different prices.
