At last! Attention iron head pilots! It's time to switch to rigid frame. The whole thing can be done without much difficulty and without messing up the original frame too much. Made by hand in the USA, Ohio, from 1" x 0.125" thick steel tube, and 5/16" thick axle plates. Fits all 1967-1978 ironhead sportsters (1967-1969: only XL and XLH). All stock installed components remain. Rear wheel, chain tensioner, axle and brake can be remounted as before. A frame mounting kit is also supplied. For correct assembly, 2" of the rear fender struts must be cut off, otherwise the frame remains untouched. The bike's dimensions will change by 4" in length and -2" in height. This means that you will need a longer secondary chain and longer brake rods.

In addition to the straight leg style bolt-on hardtail sections, that are mostly used for chopper projects of Ironhead Harley-Davidson motorcycles, Lowbrow Customs now offers rigid bolt-on hardtails sections that are inspired by the early KR race bikes with the looped frame. So if you are looking for something special for your next Ironhead Bobber project and are nostalgic about racing, you can kill two birds with one stone by using this hardtail. The frame tubes on these tail sections are bent in one piece, just like back then, and the axle plates are welded into the loop.

One great way to save money at the pump is to buy less at every fill-up. At just 1.8 gallons, our new P-Nut is about as small as a chopper tank can get. Lower fuel capacity means you'll have more time for bumming smokes and shooting the shit at every gas stop. The Lowbrow P-Nut tank features heavy gauge steel construction, 1/4" NPT petcock bungs and undrilled DIY mounting tabs for custom installation.

Nothing changes the look of your hand-built custom motorcycle like a bobber gas tank such as this. The Lowbrow P-Nut gas tanks are based on the old Wassell peanut gas tanks available in the 1950's - 70's. The Lowbrow versions are made from heavy gauge (1mm, approximately 19 gauge) steel, which translates they are much thicker, and the fabrication is of higher quality, than the originals. The Mid Tunnel Peanut has a tunnel that runs about midway through the gas tank, bringing it higher off the backbone than the original (deep tunnel) version.
