Expert Buying Guide for 2013 SRT Viper
The 2013 SRT Viper uses a 6x114.3 bolt pattern with a 71.5mm center bore. When selecting aftermarket wheels, hub-centric rings are essential to ensure proper load distribution and prevent vibrations. The offset range is 20-40mm; deviations may cause rubbing or clearance issues. Always use lug nuts with the correct 1/2-20 thread pitch and a conical (60-degree) or ball seat matching the wheel's design. Improper lug nuts can lead to wheel detachment. Verify that aftermarket wheels are hub-centric or use rings, and confirm offset compatibility with your specific suspension setup.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using wheels from other 6x114.3 vehicles (e.g., some Mitsubishi models) as their center bore may differ, requiring hub-centric rings.
- ✅ Check for brake caliper clearance, especially with aftermarket wheels, as the Viper's large brakes can interfere with certain spoke designs.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

What other years of SRT Viper have the same bolt pattern as the 2013?
The SRT Viper uses the 6x114.3 pattern from 2013 through 2014. Wheels from any of these model years are dimensionally compatible with the 2013, provided the offset and center bore also match.
How tight should I torque the lug nuts on a 2013 SRT Viper?
Refer to your owner's manual for exact specs, but always tighten the 1/2-20 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
Why is matching the 71.5mm center bore important for the 2013 Viper?
The 71.5mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
How do I measure the bolt pattern on my 2013 SRT?
The 2013 Viper uses a 6x114.3 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
Can I put aftermarket wheels on my 2013 SRT Viper?
Absolutely. Just ensure the aftermarket wheels have a 6x114.3 bolt pattern, an offset near 20-40mmmm, and a center bore of at least 71.5mm (using hub rings if larger).
