Raceline RT81 Rock 8 Wheels – Gloss Black | 17x9.5 | Jeep Wrangler 5x127
The Raceline RT81 Rock 8 is a purpose-built gloss black cast aluminum off-road wheel engineered for serious Jeep Wrangler trail and rock crawling use — available in 17x9.5 at -44mm for the 5x127 (5x5.00) bolt pattern. The RT81's aggressive -44mm negative offset is among the most extreme outboard specifications available for the Jeep Wrangler in a standard production wheel — placing the 9.5-inch-wide face dramatically outboard for the wide, planted stance of lifted JK and JL builds running large all-terrain and mud-terrain tyres. The Rock 8 name references both the eight-spoke geometry and the rock crawling application this wheel is purpose-built for.
Cast Aluminum – Gloss Black Finish
The RT81 Rock 8 is manufactured from cast aluminum alloy with a gloss black finish. The Rock 8's spoke architecture is bold and heavily reinforced — each spoke provides substantial cross-section for strength at the extreme -44mm outboard position. The eight-spoke layout with open spacing allows mud, rocks, and trail debris to clear the wheel face effectively during off-road use, maintaining traction and reducing the debris accumulation that can create imbalance on extended trail drives.
- Cast aluminum alloy: Lightweight, strong construction engineered for rock crawling and serious trail applications
- Gloss black finish: Commanding gloss black on the Rock 8's eight-spoke off-road geometry
- RT81 Rock 8 eight-spoke design: Purpose-built spoke architecture with open debris clearance between spokes
- Size 17x9.5 at -44mm: Extreme wide outboard for maximum Jeep Wrangler stance and tyre width
- 5x127 bolt pattern: Jeep Wrangler JK / JL and Jeep Gladiator JT exclusive fitment
Rim Specs – Size, Offset & Bolt Pattern
The RT81 Rock 8 is available in 17x9.5 at -44mm for 5x127 (5x5.00). At 9.5 inches wide and -44mm offset, the wheel face extends significantly outboard from the hub mounting surface — creating a dramatically wide track on lifted Wrangler and Gladiator builds. This specification targets 3.5-to-5-inch suspension lifts running 37-to-40-inch mud-terrain tyres where the wide stance and maximum tyre footprint are functional off-road requirements. Fender clearance verification is recommended for lower lift configurations before fitment.
RT81 Rock 8 for Extreme Jeep Wrangler & Gladiator Rock Crawling Rigs
The RT81's -44mm at 9.5 inches wide is a specification for purpose-built rock crawling Wrangler and Gladiator builds — where the widest possible track width, maximum tyre contact patch, and aggressive outboard stance are functional requirements alongside a bold custom appearance. Raceline's performance off-road heritage makes the RT81 an authentic functional choice for builds targeting serious rock crawling and hard trail use, not merely an aesthetic one.
Compatible Vehicles – Raceline RT81 Rock 8 Fitment Examples
- Jeep Wrangler JL Rubicon (2018–present, 5x127): The 17x9.5 at -44mm suits seriously lifted JL Rubicon builds on 3.5-inch-plus suspension with 37-to-40-inch mud-terrain tyres. The RT81's extreme outboard position creates the dramatically wide, aggressive stance of a purpose-built rock crawling Wrangler — placing the gloss black eight-spoke face at maximum practical reach on the JL platform for maximum track width on technical terrain.
- Jeep Wrangler JK Unlimited Rubicon (2007–2018, 5x127): The 17x9.5 at -44mm suits lifted JK Unlimited builds on 4-inch-plus lifts. The RT81 provides an extreme stance for JK rock crawling rigs where the widest possible tyre footprint and most aggressive wheel position are the functional objectives — a serious off-road wheel for the most capability-focused JK builds.
- Jeep Gladiator JT (2019–present, 5x127): The 17x9.5 at -44mm suits lifted Gladiator builds. The Rock 8's extreme specification at the Gladiator's bolt pattern creates a powerful, wide-stance appearance appropriate to the Gladiator's heavy-duty trail character — the truck platform's longer wheelbase accommodating the extreme offset within standard lifted arch clearance.
Why the Raceline RT81 Rock 8 Is the Extreme Outboard Jeep Rock Crawling Wheel
Buyers building seriously lifted Jeep Wrangler JK/JL or Gladiator rock crawling rigs who need 17x9.5 at -44mm outboard in 5x127, a purpose-built off-road wheel from Raceline's performance range at the most aggressive standard Jeep specification, or a functional extreme-stance gloss black wheel for 37-to-40-inch tyre builds on maximum-lift configurations find the RT81 Rock 8 to be a purpose-engineered and correctly specified choice.
