Features
- Direct replacement: IR bushings replace factory-style control arm bushings directly.
- 360-degree rotation: The inner sleeve turns a full 360 degrees for free movement at full droop.
- Hardened bearing surface: The rotating sleeve runs on a hardened bearing surface.
- Less bushing bind: Removing rotational stress reduces the bind a twisting rubber bushing creates.
- Serviceable arms: Fresh bushings and the press tool keep TeraFlex arms in service.
- Simple press tool: TeraFlex's tool kit presses bushings in with two open-end wrenches or sockets; a bench vise helps but is not required.
Description & Fitment
Kit 1952800 rebuilds a full set of eight TeraFlex short control arms on a 2018-2026 Wrangler JL with IR bushings. TeraFlex explains that a rubber bushing must twist as well as rotate, which causes bind; the IR sleeve turns a full 360 degrees on a hardened bearing surface instead. Bushings only: the press tool is sold as 1952900.

About TeraFlex
TERAFLEX.
TeraFlex describes itself as a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the range.
The company traces its roots to the 1950s and MEPCO (Military Equipment Parts Company), an early supplier of Jeep parts. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and today's catalog runs from full lift systems and the Falcon shock line to axles, steering and armor.
Authorized TeraFlex dealer. Prestige Truck is an authorized TeraFlex dealer, so what we sell is new and genuine TeraFlex. In TeraFlex's words, its limited warranty extends "only to the consumer who originally purchased the product," so keep your receipt with your build records.
Frequently Asked Questions
Will this fit my 2018-2026 Jeep Wrangler JL?
Yes, if your Jeep matches a row in the fitment table. If you're unsure, send us your VIN and we'll check.
What else do I need?
The 1952900 press tool, two wrenches or sockets, and ideally a bench vise.
Do I need new control arms after a lift?
Lifting a Jeep changes caster and pinion angle. TeraFlex sizes each kit for a lift range: preset Sport arms and Sport frame brackets suit moderate lifts, while adjustable Alpine arms let you set the length for your exact height. Plan on an alignment after any control arm change.
What is the difference between Alpine and Alpine IR?
Both are adjustable-length arms. Alpine arms use maintenance-free factory-style bushings; Alpine IR arms use TeraFlex IR (Independent Rotation) bushings, which rotate freely so the arm binds less as the suspension flexes.
Short arms or long arms?
Short arms bolt to the factory mounts and TeraFlex rates them for 0-4.5" of lift. Long arm kits are for JL Wranglers with 3-6" of lift and need the factory control arm brackets cut off the frame to fit the long arm brackets, so they are a much bigger job.
Can I replace just one pair?
Yes. Arms are sold by position as well as in 8-arm kits. TeraFlex's instructions say that if you replace a single pair to correct caster and pinion angle, it recommends the lower arms.
Installation

TypeBolt-on short arms and bracketslong arm kits need the factory brackets cut off and holes drilled
Tools
- Metric Sockets and Open End Wrenches
- Factory Service Manual
- Torque Wrench
- General Mechanics Tools
- Mineral or PAG oil
Afterwardalignment required
Here's the short version. Follow TeraFlex's install sheet (below) for your Jeep's exact steps and torque values.
- Remove one control arm from the Jeep (best done with all four tires on the ground).
- Fit the bushing replacement tool to the arm, oil the new IR bushing with mineral oil and press it in by tightening the tool with a 19mm socket and wrench.
- For axle-side bushings, disconnect the breather hose and wiring as needed, remove the old bushing with a ball joint press and press the new one into the axle until fully seated.
- Reinstall each arm and torque the bolts as printed before moving to the next.

Game changer on the trail
Made my 392 a whole new experience on the trail!!!

Worth the Money
Bought after hearing so many great things about the IR bushings and their longevity, could definitely see more flex opposed to using stock arms. For anyone running under 4.5" of lift, this is the way to go.

Installed on 2020 Jeep 4d Rubicon
Installed on 2020 Jeep 4d Rubicon with a TeraFlex 3.5 inch lift. Completed install in my driveway with jack stands. It was a little difficult to torque the nuts due to body position. Otherwise, all parts fit perfectly, no issues at all. Product is very well made and allowed me to adjust the pinion angel and wheel base. The instructions were pretty good as well. I would have preferred to know the end torque value rather than torque plus add degrees (i.e. 74ft lbs + 185 degrees).
