NOW ONLY $29.99 with free standard shipping...You cant beat that with a stick!

****This kit will only fit the Losi Trail Trekker****

 These wideners offset each side three millimeters for a total of six millimeters total.  Each spacer and barrel nut add approximately nine (9) grams to each wheel (scale in picture not included) adding a respectable 27 grams at the lowest point possible resulting in a much improved CoG. The barrel nut is flush with rim and should fit under any washer type weights. They are for sure compatible with the stock Losi wheels and Hot Racing Bead Lock alloys. The spacer is precision machined brass and the barrel nut is aircraft grade 303 stainless.  Steel is real!  Gone are the days of stripped out plastic nuts.  The stainless barrel nut are also compatible with the stock wheel wrench.  This kit is not for the Losi Micro Crawler, We have a separate kit for the Micro Crawler.  We know of no other single after market improvement to a Trail Trekker that enhances performance as dramatically as this kit. If you have or know someone who has a Losi Trail Trekker, you cannot go wrong with this custom part. We are the only producers of this product and we have just completed our fourth production run.  The first, second, and third run of over 100 kits sold quickly so don't wait.
