A Jeep Wrangler 392 (the 6.4L V8 Rubicon) on a MetalCloak 3.5-inch Game Changer suspension with Fox shocks clears 35x12.50R22 tires with no trimming — with an upgraded front driveshaft to handle the steeper driveline angles the lift creates.
This Jeep Wrangler 392 came into Juggernaut USA in Wheat Ridge (Denver), CO as a truck that mostly street-drives but needs to be trail-ready when the owner wants it. It is the 6.4L V8 Rubicon, so the power is already there — what it needed was height, the geometry to go with it, and a tire to match. We installed a MetalCloak 3.5-inch Game Changer suspension with Fox shocks, replaced the front driveshaft, added a Fox steering stabilizer, and finished it on TIS Offroad 22-inch wheels and 35x12.50R22 Comforser tires.

What's in the MetalCloak 3.5 Game Changer — and why we run it
The Game Changer is a full coil system, not a spacer. It comes with MetalCloak's Duroflex control-arm joints — Kevlar-reinforced, self-centering joints that add articulation and damp vibration — True Dual Rate coils for a ride that is both comfortable and stable, adjustable Durotrak track bars to re-center the axles, height-adjustable bump stops, and Fox shocks tuned to the dual-rate coils. Two things make it our go-to on a JL: MetalCloak kits consistently drive well both on-road and off, and they are pretty much maintenance-free over the long term — the Duroflex joints do not need the periodic greasing or the wear-part replacement that heim and poly joints demand. On a 392 that mostly street-drives, that combination of good manners and low upkeep is exactly right.
Why the front driveshaft got replaced
Lifting a Wrangler 3.5 inches steepens the angle the front driveshaft has to work through. The factory CV-style front shaft can fail at those more extreme angles, so we replaced it with a stronger driveshaft built to run at the lifted geometry. On a truck putting the 392's power through the driveline, that is not a corner to cut — it is the difference between a lift that lasts and one that fails on the trail.
Why the Fox steering stabilizer
Solid-axle Wranglers on 35-inch tires are prone to bump steer and steering feedback over rough ground. A Fox steering stabilizer damps that out so the 392 tracks straight and stays settled through washboard and rocks instead of fighting the wheel.
Do 35s fit a JL 392 with a 3.5-inch lift?
Yes — the 35x12.50R22 tires cleared on this 392 with the MetalCloak 3.5-inch Game Changer and no trimming required. They fit without any issue. That is one of the reasons a 3.5-inch system is a common target height for a JL that wants 35s with room to flex.
How the install went
Clean. The Game Changer bolts to factory mounts, and the driveshaft and stabilizer went in without a fight. The work on a build like this is doing it in the right order — set the lift, correct the driveline, dial the steering, then the wheels and tires — so the geometry is right before it rolls out.
Common questions on this build
Do 35s fit a Wrangler 392 with a 3.5-inch lift?
On this build, yes — 35x12.50R22 tires cleared with no trimming.
Does a lifted 392 need a new front driveshaft?
We replaced it here. At 3.5 inches the factory CV-style front shaft can fail at the steeper angle, so a stronger driveshaft keeps the driveline reliable.
Why MetalCloak on a JL?
They drive well on-road and off, and they are close to maintenance-free long term — the Duroflex joints do not need the greasing or wear-part replacement that heim and poly joints do.
