About this part

This is a set of two JConcepts Hazard Wheels with a 12mm Hex, and 3mm Offset. These wheels fit the Associated SC5M and SC10 4x4 with no modification, as well as SC10 trucks with 12mm hex adapters.

Short Course trucks have evolved into high-performance racing vehicles and adjustability is always the key to success. Introducing the Hazard 12mm hex wheel for the SC10 4x4 and SC10 by JConcepts. A powerful new look that combines the winning combination of a 10 spoke design, bead-lock appearance and center lug nut detail with a hint of inspiration from yesteryear. The Hazard will make an immediate impact on the performance of the SC10 trucks by widening the stance of the truck by 6mm in overall width. The increased width will maximize the SC10 and bring it up to the ROAR maximum legal limits in dimensional width.

Already a champion, the Hazard wheel earned the top qualifying position and 1st place at the 2011 ROAR Off-Road Nationals in the Pro 2 modified class in the hands of Ryan Maifield. A dominating performance taking the TQ in the first 3 rounds of qualifying and 1st place in A-main #1 and 2 to take retain the title for JConcepts.

By nature, Short Course trucks have a high center of gravity and tend to feel light or tippy in high-speed sections. There is no better way to improve on-track stability than to add width, and with the Hazard wheels, sweeping through the high-speed corners gets a little easier. Wheel profile, interior and exterior ribbing and spoke design were all areas of focus while creating the combination of durability, clearance, functionality and appearance. With the black color and a matte face appearance, being unique is worry free as practically any paint scheme can be matched to these exciting wheels. The hassle-free and lightweight 1-piece design creates the ultimate race and show wheel for any competition.

NOTE: To use the 12mm hex wheel on the SC10 requires JConcepts part JCI2081 for the rear, or the Team Associated inboard hub hex conversion components for the front and rear (ASC9883, ASC9880, and ASC9881).

Features:

  • Original 1:1 inspired JConcepts Hazard 12mm hex design
  • 3mm per side additional width in offset
  • Direct bolt-on fit for the SC10 4x4
  • Bolt-on fit for the SC10 with 12mm hex adapters
  • Durable design, finish and material
  • Black in color with matte face appearance
  • Hassle free and lightweight 1-piece design
  • Devastatingly handsome

12mm hexes are undersized. Does not fit well on the SC10. Wheels wobble on the truck (I blame on the poor fit). Even after tightening them to the point I thought I'd break something, wheels still wobble on the front. And, good luck getting them off. NOT recommended!

I have these wheels, the added track width is definitely noticeable. Yes the hexes are tight, but they are supposed to be that way!! I think all wheels should be +3, these are good wheels at a great price.

I run these on my Sc6.1, and have had no issues with cracks or the hex tolerance problems people have mentioned from years past.

I'm not sure what everyone is talking about when they say the rims are too tight on the hex or they've cracked and split. I've had no problems at all and I have them on all four wheels on my SC10. I just bought four more of these too. FYI the 3mm offset makes a big difference in handling.

What reviewers say

Several report that the hex fit is very tight, with some saying the hexes pull out of the wheel when removed and need a screwdriver or pliers to pry off. Others say the tight fit is expected and cause no problems. Reports of cracks and splits appear in some reviews, including one describing brittle plastic after a single qualifier, while others report no cracking. Multiple reviewers praise the added track width and handling from the 3mm offset, and several say it suits their SC10 or similar trucks. Fit and durability experiences vary, and some reviews describe the wheels on different chassis.
