Longfield Super Finish Toyota 8" IFS Clamshell Ring & Pinion Gears

Looking for a Ring & Pinion that you can rely on even on the most punishing trails? Longfield is proud to offer Longfield Super Finish Ring & Pinion Gears. These are the very same gears that have won multiple championships in professional desert racing & competitive rock crawling circuits and have proven themselves on some of the most grueling off-road courses in the world.

What makes Longfield Ring & Pinion Gears the best on the market?

Better Materials: Longfield use heat-treated 8620 chromoly tool steel for strength and wear resistance.

Better Gear Teeth: Longfield only use the 5-cut process on the ring gear teeth instead of the cheaper 2-cut process used by most other aftermarket vendors. The 5-cut process results in teeth with a tapered tooth profile. This increases contact area and spreads the contact load along a wider area, resulting in less stress on the ring gear teeth.

Better Machining: The gear teeth are cut using Gleason CNC hobbing machines & cutters. Gleason gear-cutting technology produces an unprecedented level of accuracy and surface finish, which allows the gears to transmit more torque and improve fuel efficiency. The higher accuracy and surface finish also produces a quieter-running gear set, which means they will work great on the daily driver too.

Better Finish: Longfield's Super Finish gears allow you to skip the break-in period and get on the trail now! The aerospace-grade REM® Isotropic Super Finishing (ISF ®) process removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 µin average surface roughness. This means that there is less friction between the gears, reducing wear by 95% and allowing the gears and bearings to run cooler and last longer.

Better Value: Longfield go directly to Tier 1 OEM manufacturers to have gears made to Longfield's exact specifications. By cutting out the middlemen, Longfield can offer the highest quality gears at a competitive price.

On Toyota trucks we recommend 4.88's for 33" tires and 5.29 for 35" and larger.

For Toyota 8" IFS Clamshell front axles only. Will not fit 7.5" IFS front axles or 8" solid axles.

Specifications:

• Made from tool-grade 8620 steel and heat-treated for maximum strength and wear resistance.
• The gear teeth are cut using Gleason CNC hobbing machines & cutters. Gleason gear-cutting technology produces an unprecedented level of accuracy and surface finish, which allows the gears to transmit more torque and improve fuel efficiency.
• Gear teeth are cut using the 5-cut process to increase contact area to reduce load distribution and reduce stress on the gear teeth.
• Higher accuracy and surface finish also produces a quieter-running gear set.
• No break-in period.
• Less friction.
• Reduced wear allowing bearings and gears to last longer.
• Treated with REM® Isotropic Super Finishing (ISF) process.
• The REM® Isotropic Super Finishing (ISF) process removes the microscopic peaks in the material and creates a surface on the ring and pinion gears with a roughness of less than 10 µin Ra! This means that there is less friction between the gears, reducing wear by 95% and allowing the gears and bearings to run cooler and last longer.
• Non-directional surface that increases lubricant retention on the gear surface, reducing lubrication requirements.
