The best Cat 1 to Cat 2 bushings depend on which hitch connection you need to adapt. For Category II lower lift arms connecting to Category I implements, IFERLA, Antrys, and Nvguoes offer lower lift arm bushings; choose a pack size and material that match your needs. Koch Industries makes a different style of reducing bushing for a top link. Check the dimensions and hitch location before ordering, since these products are not all interchangeable.

IFERLA 5-Piece Lower Lift Arm Bushings
This IFERLA set is best for owners who need a smaller supply of Category II-to-Category I lower lift arm adapters. The listed function is to let Category II lift arms connect to Category I implements. The product description lists compatibility with replacement numbers including 302910, 30291E1, EC0NG992AA, and 87760407.
The bushings are described as brass, with a 1-3/4-inch length, 1-1/8-inch outside diameter, and 7/8-inch inside diameter. Those measurements make it easier to compare the part against an existing bushing. Choose this set if its dimensions and replacement numbers match your setup. The listing does not establish fit for every tractor or implement, so verify measurements before purchase.
IFERLA 10-Piece Lower Lift Arm Bushings
This 10-piece IFERLA option is best for buyers who want more bushings on hand for multiple implements or replacement needs. It shares the listed purpose, brass material, dimensions, and replacement-number range of the 5-piece IFERLA set. The stated size is 1-3/4 inches long, with a 1-1/8-inch outside diameter and 7/8-inch inside diameter.
Choose this larger pack over the 5-piece version if the additional quantity suits your work. It is still a lower lift arm bushing, not a top-link reducer or a complete quick-hitch adapter kit. Confirm the required number of bushings and compare the dimensions with your hitch components before ordering.
Antrys 10-Piece Hitch Adapter Bushings
Antrys is best for buyers looking for lower lift arm bushings described as minimizing play between tractor and implement. The product is intended to adapt Category II lift arms for Category I implements. Its listed replacement numbers include 302910, 30291E1, 87760407, P2008GV, and 303000.
The listing says the bushings are designed for a snug connection and that they meet or exceed original manufacturer specifications. It does not provide dimensions or specify a material in the supplied product details. Choose this option if its part-number information matches your application, but confirm dimensions with the seller or product listing when exact sizing is important.
Nvguoes 10-Piece Lower Lift Arm Bushings
This Nvguoes set is best for buyers comparing replacement numbers and seeking a lower lift arm adapter described as iron-plated brass. It is intended to connect Category II lift arms to Category I implements. The listed replacements include 302910, 30291E1, EC0NG992AA, 87760407, FX00351, and other numbers.
The product description says the bushings are designed for a tight, play-free connection and heavy lifting. No dimensions are included in the supplied details, so compare the listing with the bushing currently installed rather than assuming it matches the IFERLA measurements. Avoid choosing by replacement number alone if the physical size is uncertain.
Koch Industries Top Link Reducing Bushings
Koch Industries is best for buyers who need a top-link reducing bushing rather than lower lift arm adapters. The pair is described as allowing Category I implements to be used on Category II tractors. Each bushing has a 1-inch outside diameter and a 3/4-inch inside diameter.
This is a different hitch location and size from the lower lift arm products above. Choose it only if you need a top-link reducer and the listed dimensions match your connection. It is not a substitute for a lower lift arm bushing set.
Buying Guide: How To Choose Cat 1 To Cat 2 Bushings
Which hitch connection are you adapting?
Start by identifying whether the bushing belongs on the lower lift arms or the top link. Lower lift arm bushings connect Category II lift arms to Category I implements. A top-link reducer serves a separate connection, so matching the category labels alone is not enough.
Do the dimensions match your hardware?
Compare the bushing’s inside diameter, outside diameter, and length with the pin and hitch opening. Of the lower lift arm options here, IFERLA lists specific measurements: 7/8-inch inside diameter, 1-1/8-inch outside diameter, and 1-3/4-inch length. The Koch top-link pair lists different dimensions.
How many bushings do you need?
Pack sizes vary from five to ten for the lower lift arm options. Consider how many implements you plan to outfit and whether you want replacements available. A larger pack is useful only if you need the additional pieces.
Should you match a replacement number?
Use listed replacement numbers as a comparison aid, not as the only fit check. Confirm the hitch position and measurements before ordering. Product descriptions do not establish universal fit for every tractor and implement combination.
Frequently Asked Questions
What do Cat 1 to Cat 2 lower lift arm bushings do?
They adapt Category II tractor lower lift arms to connect with Category I implements, when the bushing dimensions and application match.
Are lower lift arm bushings the same as top-link bushings?
No. They serve different hitch connections. Check whether you need a lower lift arm adapter or a top-link reducer before buying.
What dimensions should I check?
Check inside diameter, outside diameter, and length, then compare them with the pin and hitch components where the bushing will be installed.
Do replacement part numbers guarantee fit?
No. Replacement numbers can help identify a possible match, but confirm the physical dimensions and intended hitch location.
What is the difference between the two IFERLA sets?
The listed difference is quantity: one pack contains five bushings and the other contains ten. Their supplied descriptions give the same material, dimensions, and replacement numbers.
