Factory Hurst master rebuild kit for 1966-and-newer Competition/Plus four-speed shifters, for a stick that flops between gates or fights reverse.
If the four-speed in your muscle car has a Hurst Competition/Plus shifter that flops between gates, hangs on the 1-2, or lets reverse go in too easily, the mechanism inside the housing is worn out. Hurst's own master rebuild kit, part number 3327303, carries every wear part needed to rebuild a 1966-or-newer Competition/Plus, so the shifter comes back tight and positive without hunting down a used core.
A Comp/Plus is a stack of three shift levers (1-2, 3-4 and reverse) sandwiched with thin plates inside a steel housing. The stick rides in a receiver and carrier that pivot on a bushing, and a selector plunger picks which lever the stick is driving. The interlock plate keeps two levers from moving at once, a reverse safety plate and spring-loaded reverse plunger make you deliberately lift or push to get reverse, and a wave plate keeps the stack tight. Hurst's parts list for this kit is the neutral alignment pin, pivot bushing, two 0.008 in wave plates, the 0.042 in interlock plate, the 0.015 in reverse safety plate, dust cover, stop screws and jam nuts, selector and reverse plungers, bridge plate, nylon washer, locknut, spring washer, reverse spring washer, stick return and reverse springs, carriage bolt, roll pins, a tube of grease and a jackscrew with nut for spreading the housing. You reuse your housing, cover plate, carrier, receiver and the three shift levers.
Disconnect the shift rods at the shifter and work the transmission levers by hand. If each gear selects cleanly at the transmission, the trouble is in the shifter or its rods and bushings. If the box still grinds or jumps out of gear with the shifter off, look at synchros, the clutch and the gear set instead; for a GM four-speed that may mean a Muncie synchro and bearing kit rather than a shifter rebuild. Our manual versus automatic repair cost guide shows what each kind of repair usually costs.
Hurst lists this kit for Competition/Plus four-speed shifters from 1966 on. The shifter mechanism is common, but the shift levers differ between models, and the brackets and rods that suit a particular transmission come in a separate Hurst installation kit. This rebuild kit does not include levers, rods or a bracket. Look for the Competition/Plus name on the housing before ordering, photograph your lever positions before you take it apart, and if you are not sure what you have, send us a photo. For other gearbox hardware, see our hard parts category.
If you are refreshing the whole drivetrain on a GM four-speed car, a Muncie four-speed bellhousing and the McLeod hydraulic release bearing are the other pieces that wear in the same area.

No. Hurst's parts list covers plates, plungers, springs, the pivot bushing, hardware, grease and an alignment pin. You reuse your shift levers, housing, carrier and receiver, and rods and brackets come from the Hurst installation kit for your transmission.
Hurst lists the kit for Competition/Plus shifters from 1966 and newer, so a 1969 shifter is covered. Check that the housing is a Competition/Plus and not a different Hurst model.
The reverse safety plate, reverse plunger and reverse spring create the lockout. When they wear or the spring weakens, reverse can be selected without the extra effort it should take. All three are in this kit.
Hurst recommends new shift rod bushings if you reuse an existing installation kit. Worn rod bushings cause the same sloppy feel as a worn shifter.
Basic hand tools, a vise, a punch, safety glasses and vise-grip pliers. The kit includes the jackscrew for spreading the housing and the pin for setting neutral.
