Do not assume it fits a bike or engine that is not named here; ask the store first. - [TB Parts > Z50 79-87 > Z50 79-87 Chassis Parts](https://tboltusa.com/store/z50-79-87-z50-79-87-chassis-parts-c-68_1064_74.md) Where a fitment line says "All", it means all years of the model named on that line, not all bikes. ## Description (the store's own text) TBparts Extended body kit #2 for K3 and up z50. This kit will not work with the first 2 hard tail models, soft tail Z50s only. This kit includes the following for the best price possible: **TB Front Fork Kit – Z50 72-99** TBparts Upgraded Z50 Front fork kit. Includes everything in the picture – High Quality KLX110 style forks with Heavy Duty Springs, billet triple clamps, billet risers, longer axle, brake cable, cable bracket, and billet hub stop. **Key Features:** - +5″ and adjustable down to +3″ - Fits all 1972-99 Z50s, but recommend using with our Plus 3” extended swing arm and our 330mm rear shocks. Will work with +1.5″ swingarm and 280mm shocks - Kit reuses stock hub and spacers – Includes 4 M12 washers as spacers for a perfect fit. - See last 3 product pictures of TBW9151 for installation reference **TB Swingarm, Plus 3″ – Z50 K3-78 & Z50R 79-99** Its a very high quality aluminum swingarm that increases strength and improves handling on the Z50. The old version was used on our Vegas Mini Moto winning Z50s (as well as in many other races) and this new version is even better suited for racing or backyard fun. Unlike many other similar looking Z50 swing arms on the market this one uses solid billet aluminum sections, the pivots use bearings instead of the stock type rubber bushings, and it was purposely designed for adult abuse. Please compare closely to the competitors. These are definitely not the cheaper poor quality aluminum Chinese $75.99 ebay specials you see around that will snap after a couple jumps. **Key Features:** - Uses solid billet aluminum sections for increased strength - The billet center section is notched into the billet side sections and then bolted on for increased strength (Most are hollow and welded on) - The shock mounts have been redesigned for increased strength - The chain slider is easily removed and replaced with two screws (was previously riveted on) - Its 9 5/8 inches from the cross member to the centerline of the axle when adjusted all the way back. This clearance allows you to run the most aggressive knobby tires. **TB Rear Shock Set – 330mm Chrome** For adults/teenagers riding mod Z50 or CT70s in the dirt or on the street, you are going to want heavier duty shocks and these fit the bill at an affordable price. **Key Features:** - Preload Adjustments - Oil Damping - High quality surface finish - 330mm **TB High Rise MX Handlebar kit, Silver- 7/8″** TBparts 7/8″ High Rise Silver Handlebar. We have been racing with these for years and recently started supplying Nitro circus race bikes with them as well. You cannot beat them for the price and we have put the testing in on them! **Specifications:** - 6″ rise - 7/8″ OD (Will not fit factory XR/CRF50 bar clamps) - 29″ wide **Handlebar kit includes (besides handlebars):** - Grips - TBW1186 - Throttle Assembly - TBW1051 - Lever Set - TBW1165 - Throttle Cable - TBW0301 ## Shipping and returns - Flat rate shipping is $8 for parts orders under $75 and free for most parts orders over $75, within the continental 48 states.
